The invention relates to a workwear as described in the preamble of claim 1.

In the field of welding technology remote control devices for communication with components of a welding system are known from the prior art, which are designed in the manner of a mobile control panel that is portable and portable carried by a person. Such a remote control device is known for example from WO 03/022503 A1.

Furthermore, garments are already known in the art, in which a variety of electrical systems are integrated. Such workwear is disclosed, for example, in EP 1 253 695 A2.

EP 1 253 695 A2 describes a system for the wireless transmission of electrical power, as well as a garment with such a system. In this case, electrical circuits in garments with electrical devices and / or electrical circuits in other garments wirelessly, preferably inductively coupled, being transmitted through the coupling electrical power and, where appropriate, information. The electrical appliances are portable devices such as e.g. Audio players, mobile phones, data storage devices, navigation devices, etc., which are powered by electricity. According to EP 1 253 695 A2, however, it is only possible to operate equipment specially equipped for inductive signal transmission in the vicinity of a receptacle or an inductive coupling device of a garment.

A disadvantage of the solutions known from the prior art is that in the field of welding different components of a welding system, such as a welding power source, an input or output device for a welding machine, a control device for the welding system, etc., so far only about a structurally independent, stationary control panel are accessible, so that there are significant limitations in his freedom of action for a person. Further, in the prior art electronic garment systems, the establishment of a direct communication link with various components of an industrial manufacturing facility, such as an industrial manufacturing facility, e.g. a welding system, to influence on this without an additional device not possible.

Further, in the field of welding technology, workwear is known which has one or more protective zones of heat- and / or UV-resistant material for shielding or reducing these radiations. A disadvantage of these workwear for welding that protection of a person from other types of emissions generated by a welding system in welding processes, in particular electrical and / or magnetic fields, is not possible. In the field of electrical welding systems, electrical and magnetic radiation in the area of the current-carrying lines occurs to a greater extent, for which reason welding personnel are particularly exposed to the effect of these potentially harmful fields. With the work clothing known in the prior art attenuation of these fields, in particular the magnetic fields, due to the lack of suitable devices not possible and it is the person unabated exposed to the acting, magnetic or electric radiation. In welding systems is particularly problematic that a reduction of the magnetic field strengths by maintaining a distance to the field generator is not possible or only with uncomfortable measures, since the current-carrying lines open into the area of the welding torch, which is often performed manually by the person.

Sensors for detecting different types of parameters, such as temperature, sound, etc., which are parts of independent measuring systems or measuring devices, are also known in the state of the art. It is a fact that in the field of welding systems there is a strong change in the environmental conditions, with state variables or parameters, such as the gas composition in the room, the temperature, a sound level, electrical or magnetic radiation, suspended particles etc. change the environment and these 3 AT 503 678 B1

Environmental parameters cause an increased physical stress for a person in the area of the welding system at inadmissible concentrations or values. Failure to comply with preventive measures to avoid health-damaging environmental conditions therefore increases the health risk for persons in the area of welding equipment. In order to determine a health hazard in the welding environment, it is disadvantageously necessary in the prior art for the person to carry independent measuring systems which carry out an environmental analysis or analysis to determine health-threatening conditions. The ease of use of welding systems and the productivity of welding processes is limited by the increased effort and it is not possible with the known from the prior art measuring systems to actively intervene in the welding process to change the environmental parameters.

The object of the invention is to provide a workwear with which the use or. Ease of use of welding systems for these people serving is improved. Optionally, it is an independent object of the invention to provide a work clothing or a welding system, with a more comprehensive protection or provision for a person before by a welding system or a welding process outgoing health hazards is possible.

The object of the invention is achieved by the reproduced in the characterizing part of claim 1 features. The advantage resulting from the arrangement of a protective device in the protective zone of a workwear lies in the fact that the electrical and magnetic fields produced by a welding process carried out by means of electrical energy in the region of the electrical conductors do not have any or a reduced effect by reducing the field strengths the body of a person operating the welding system or a person wearing the sweat-wearing clothing is exercised and physical or biological processes in the body caused by the electric and magnetic fields which may cause possible undesired effects in the tissue, nervous system, etc. are prevented or reduced ,

With a shielding element for electromagnetic radiation, as defined in claim 2, spatially behind the shielding element lying areas in a structurally simple manner, for example, by a dissipative or compensatory acting shield, be shielded.

It is advantageous embodiment according to claim 3, since the different types of electric and magnetic fields occurring during welding processes, both low-frequency fields in the range of 0 to 30 kHz and high-frequency electromagnetic waves greater than 30 kHz, are shielded.

In the claims 4 and 5, advantageous, structural embodiments of the shielding element for use as a liner or intermediate layer or outer or inner layer of a workwear specified.

In the claims 6 and 7 expedient embodiments of the Schirmungslage for a one-piece and thus space-saving, permanent arrangement of the same are described in the work clothes.

An embodiment according to claim 8 is advantageous, since such Schirmungslage is particularly suitable for shielding low-frequency magnetic fields, whereas the Schirmungslage is suitable in accordance with claim 9 due to the Faraday effect, in particular for shielding high-frequency electromagnetic waves.

By the features described in claim 10, the advantage of a shielding effect is achieved by the corresponding fibers of shielding material, being formed by the braid or fabric a flexible or adaptable protection zone on the workwear, so that the wearing comfort of a workwear is not limited or insignificant.

With an embodiment according to claim 11, a variable arrangement of the Schirmungselementes is possible in an advantageous manner, so that the protection zone can be moved at different welding positions of a person.

Advantageous are the features specified in claim 12, since ferromagnetic materials have a high permeability, which allows efficient shielding of magnetic fields in the low frequency range up to 30 kHz, the known from the prior art, 80% iron-nickel Alloy of the so-called MU-metal, as described in claim 13, represents a particularly suitable material for the shielding element.

Furthermore, the features according to claim 14 are advantageous, since the effect of a Faraday cage, which extends around a person, can be utilized for shielding the interior of the work clothes from electric fields by this configuration.

Due to the features of claim 15, a heat or UV protection in the protection zone is advantageously achieved in addition to the protection against electric or magnetic fields, wherein by means of the heat-resistant material layer, a heating of the Schirmungselements, in particular to the Curie temperature of 768 ° C for iron or 360 ° C for nickel, is prevented.

By means of a grounding line according to claim 16 can be derived by structurally simple means static charges and acting on the shielding electric fields to earth.

An embodiment according to claim 17 is advantageous since a compensator for active magnetic field compensation represents a controllable or controllable means for shielding or reducing electromagnetic fields. By means of an opposing field generated by the compensator, which is directed counter to the magnetic field of the welding system in the field direction, weakening or mutual extinction of the fields can be achieved.

Due to an embodiment of the compensator according to claims 18 to 20, a particularly expedient reduction or reduction of the electrical or magnetic fields of the welding system by controlling the field strength or the field orientation in space is possible.

Furthermore, work clothing is described in which it comprises an analysis device for one or more parameters of environmental conditions, for example a gas composition, in particular air composition, a temperature, a sound level, a degree of humidity, electric and / or magnetic fields or waves, suspended particles, or the like, The analysis device assigned to the work clothing advantageously makes it possible to detect and evaluate one or more parameters of the environmental conditions or of the room in the area of a welding installation. In the analysis area, it is therefore possible to detect impermissible concentrations or values of ambient parameters that exceed impermissible threshold values, so that either manually for a person operating the welding system or automatically through the welding system there are possibilities for preventing or reducing the occurring loads. The main advantage lies in the integration or linking of the analysis device and workwear for welding work, since such work wear, such as a welding overalls, welding gloves, a protective screen or the like. Always worn by a person welding during the welding process and this in the hazard area of Welding system is located. An additional effort in the operation of a welding system by external measuring systems to be carried along can be prevented, so that for a user an improvement in welding safety and protection against health hazards is achieved and at the same time the handling of the welding system is not or only slightly deteriorated ,

The term workwear 1 encompasses all types of garments that can be worn by a person 2, which are especially designed for welding work, i. Areas of heat-resistant, refractory or flame retardant or resistant to ultraviolet radiation materials. For example, the workwear 1 as a glove, shoe, pants, a jacket, coat or sweater-like shirt, a one- or multi-part coveralls, a radiation protection device for the field of vision of a person, especially an eye shield, goggles, cap, a carrying strap or the like ., Where the workwear is preferably designed specifically for welding. Workwear 1 can be formed, at least in part, from textile fabric material such as cotton or polyester, it being understood that all known from the prior art in the field of clothing or textile technology, especially in the field of welding or protective clothing known materials are used. Possible types of components 5, which may include a welding system 3, are described below. Thus, the welding system 3 for carrying out a known from the prior art welding method, for example, a MIG / MAG; TIG, TIG, stick electrode, laser welding process or the like, be formed and for this purpose a current source 6, a power part 7 and a control device 8 and the power part 7 and the control device 8 associated switching member 9, have. The switching member 9 and the control device 8 is connected to a control valve 10, which is arranged in a supply line 11 for a gas, in particular a protective gas, such as nitrogen, helium or argon and the like., Between a gas reservoir 13 and a welding torch 14. In addition, a wire feed device 15 can also be actuated via the control device 8, a welding wire 17 being supplied from a supply drum 18 to the region of the welding torch 17 via a supply line 16. The energy for building an arc 19 between the welding wire 17 and a workpiece 20 is supplied via welding lines 21, 22 from the power section 7 of the power source 6 to the welding torch 14 and the welding wire 17 respectively, a first, e.g. positive potential, in particular via the welding line 21 of the power source 6 is applied to the welding wire 17 and the further, e.g. negative, potential, in particular via the further welding line 22 on the workpiece 20 is present.

For cooling the welding torch 14, this can be connected via a cooling circuit 23 with the interposition of a flow monitor 24 with a coolant tank 25, in particular a water tank, so that when commissioning the welding torch 14 of the cooling circuit 23 can be started by the control device 8, thereby cooling the Welding torch 14 is reached.

Furthermore, the welding system 3 can have an input and / or output device 26, which has 7 AT 503 678 B1, for example. from controls, a keyboard and / or a display element, such as a keyboard. a screen or a display exists, with the various welding parameters or modes of operation of the welding system 3 can be adjusted. In this case, the values set or selected via the input and / or output device 26, in particular welding-specific parameters, are forwarded to the control device 8, so that the individual components are subsequently output by the control device 8 in accordance with the predetermined values or the control functions or values derived from these values Control signals can be activated.

A separate solution according to the invention relates to workwear 1, whose signal transmission system comprises the remote controller 4 or the remote controller 4 alone, which can be brought into electrical connection with a component 5 of the welding system 3 for controlling and / or regulating or monitoring the same. Electrical connection means that the implementation of a unidirectional or bidirectional signal transmission can take place, in which case the transmission of information or data and / or the transmission of electrical power, so voltage and current, can take place and this signal transmission is performed wirelessly or by wire.

In Fig. 2, the work clothing 1 according to the invention with the remote controller 4 for welding control or control purposes or monitoring purposes, as well as a communicating with the remote control 4 communicating, for automated production of welded joints serving welding system 3 is shown in more detail. In such welding systems 3 movements of the welding torch 14 are made by a manipulator of a robot system 27, wherein the configuration of parameters, functions, operating modes, Schweißteilgeometrien, trajectories, etc., the manufacturing plant or welding system 3 is performed by a person 2. For this purpose, corresponding control signals or data are transmitted from the electric remote control 4 to the power source 6 or the input and / or output device 26, in particular a setting console 28 for the welding device or else the robot system 27.

In a preferred embodiment, the electrical remote controller 4 is assigned an operating device 29, to which different settings of one or more components 5 of the welding system 3 can be made. The operating device 29 has for this purpose one or more adjusting members 30 and / or an output device 31. The remote controller 4 further has an electrical interface 32, via which a communication connection with the components 5 of the welding system 3 can be produced. The adjustment members 30 and output means 31 are electrically connected to the interface 32, i. that upon activation or actuation of an adjusting member 30 to the interface 32, a signal or an individual characteristic value for the respective adjusting member 30 is transmitted and this characteristic value or a value generated from this in a further consequence by means of the interface 32 to the desired component 5 of Welding system 3 is transmitted.

Another possibility is that of one of the components 5 to the interface 32 of the remote controller 4, a signal representing, for example, the current state of the welding system, i. active welding process or downtime, welding parameters or the like., Is sent, whereupon the output device 31 is triggered or activated in response to this signal for signaling the state of the welding system 3. Thus, unidirectional or bidirectional communication, in particular signal and / or data transmission, can take place between the components 5 of a welding system 3 and the remote controller 4.

As adjusting members 30 known from the prior art switching devices, such as buttons, rotary or slider, toggle switch, an electrical location detection, in particular touchscreen, etc., may be provided. The output device 31 may be formed by optical display means 33, for example lamps, such as filament lamps, LEDs and / or displays such as LCD or TFT screens, or as an acoustic signal transmitter, vibration signal encoder or the like.

As shown in Fig. 2, it is now possible by means of the remote control 4 on the work clothes 1 to make settings on the welding system 3 via the operating device 29, wherein the necessary adjustment organs 30 or output devices 31 of the operating device 29 on the work clothes 1 or detachable permanently arranged at this or are integrated in this. Due to the structural combination of the remote controller 4 with the workwear 1, a person can make 2 settings on a standing with the remote control 4 operatively connected component 5 of the welding system 3, for which no settings on the stationary input and / or output device 26 must be made, as was the case in the prior art so far.

The possibility of influencing or configuring the welding installation 3 by means of the remote control 4 is illustrated in FIG. 2 with reference to the input and / or output device 26 provided in the manner of a setting console 28 on the welding installation 5.

By making adjustments to the operating device 29 of the remote controller 4 parameters or menu items at the input and / or output device 26 of the welding system 3 can be changed, for this purpose the setting options are visualized on the display 28 on a display 34 or other display devices, in particular virtual menu guidance is provided. Of course, via the remote controller 4, a control device 8 of the welding power source 6 to specify or query parameters of the welding system 3 are addressed directly.

The setting members 30 of the remote controller 4 are assigned or manually assignable control functions that are processed on the component 5. The adjustment members 30 may be provided, for example, in the manner of navigation, selection, confirmation or cancel keys, etc., or may be assigned functions manually, with the respective adjustment members 30 generating representative signals and values upon actuation thereof and these values or the control functions ascertained from these values by the remote controller 4 are transmitted by means of the interface 32 to a corresponding interface 35 of the component 5 or the setting console 28 and are subsequently evaluated by a control device 8 assigned to the welding system 3 or component 5. After completion of the adjustment process via the remote controller 4 can, in particular via a control line 36, the welding power source 6, if necessary, the parameters for the welding process or the position coordinates for the robot controller 27 are transmitted and it can be the actual workflow for a welding process to be performed independently of the remote controller 4 or be started under continuous signal exchange between remote controller 4 and component 5.

In Fig. 2 communication lines 37, 38 are shown in dashed lines, which symbolize the electrical connection of action of the remote controller 4 with the components 5 of the welding system 3. The communication connection between the remote controller 4 and the component 5 can take place via a known from the prior art transmission method, for example - as symbolically represented by the arrows 39 - wirelessly by radio, infrared, magnetic induction, or wired via lines to the analog or digital signal transmission. The remote controller 4 can address a single interface 35 of a component 5 of the welding system 3 via the interface 32 or communicate with several interfaces 35 of different components 5, for example two separate power sources 6, for which purpose the individual interfaces 35 assigned identifiers, frequency ranges or the like on the Interface 32 can be sent to ensure a defined signal transmission between components 5.

In Fig. 3 the basic structure with the individual modules of the remote controller 4 is shown as a block diagram. The remote controller 4 has the interface 32, which comprises a physical transmission element 40 and optionally an interface driver 41. The interface 32 is bound to an electrical transmission system 42, wherein the transmission system 42 is formed for example as a data bus system 43 for digital signal transmission and for transmitting a supply voltage. It should be noted that the transmission system 42 may also be designed to exclusively carry out an analogue signal transmission for the transmission of electric power via one or more lines, but in addition an information transmission by the coding of voltage levels via a signal processing means, e.g. via modulation or demodulation, may be possible. The transmission system 42 is formed for example by flat or thin conductor layers, in particular copper conductor tracks, which are attached to a flexible band, for example made of plastic, so that a flexible element for electrical signal transmission is formed, as will be described in more detail below, or The conductor layers are integrated directly in the workwear 1, for example, woven into a lining of a textile workwear 1 or arranged in a rigid section of a workwear 1, in particular molded or cast, is.

It is further connected to the transmission system 42, the operating device 29, in particular the at least one adjusting member 30 and the output device 31. Furthermore, with the transmission system 42, a control device 44 for performing logical operations, in particular a microcontroller 45, and a memory device 46, in particular a rewritable ROM memory or the like. Or another, known from the prior art digital, optical or magnetic memory be connected. To enable operation of the remote controller 4 this can be assigned to a power supply device 47 for generating the necessary operating voltage. In addition, communication system 48, for example comprising a physical transmission element 49 and an interface driver 50, can be connected to the transmission system 42, with which a communication link to a remote station 51, for example a public communication network 52, e.g. an Internet, Ethernet or the like, or a device 53 can be produced.

As already described above, via the interface 32 with a component 5 of the welding system 3, e.g. as shown in Fig. 3 with the control device 8 of the welding power source 6, for controlling and / or monitoring a welding process, a signal and / or data transmission are performed. Corresponding control signals are generated by the adjusting members 30 and transmitted to the transmission system 42 and transmitted to the interface 32 by means of a clock generator associated with the control device 44, in particular the microcontroller 45. The controller 32 may by means of the interface driver 41, which may be stored as processable by the microcontroller 45 software in the memory device 46 or may be formed as a physical driver circuit, make a coding of the control signal into a component 5 understandable transmission protocol, so that compatibility between the remote controller 4 and the component 5 is ensured. For example, standardized transmission methods such as Bluetooth ™, WLAN (Wireless Local Area Network) or the like can be used for this purpose. It is further noted the possibility of a wired communication link between the remote controller 4 and a component 5 of the welding system 3, the interface 32 for this purpose, for example, for communication with industrial bus systems such. Fieldbus, CAN bus (Controller Area Network), Interbus-S, Profibus, etc. is formed. Another functionality of the remote controller 4 may be that a stored in the memory device 46 program logic via the interface 32 or the communication device 48 read or a program logic can be stored in the memory device 46 so updates for updating of the stored in the memory device 46 Software are feasible.

The communication by means of the communication device 48 and a remote station 51 may be similar to that described above for the interface 32, wherein the remote station 51 10 AT 503 678 B1 is not a component of the welding system 3 and this is not associated. Thus, for example, it is possible by means of the communication device 48 directly to a public communication network 52 can be accessed, for which purpose the transmission element 49 is provided by a known from the prior art modem or a transmitting and / or receiving unit for wireless radio data transmission over a mobile network and the interface driver 50 converts the internal signals of the remote controller 4 to a format defined by a transmission protocol. An equally possible embodiment variant in which a communication connection with the electrical device 53 is established by means of the communication device 48 is described in greater detail in the course of FIG. 6 at a later point.

It should generally be noted in relation to the remote controller 4 that in various embodiments this may only consist of parts of the modules described above or shown in FIG. 3 or only parts of the modules may be arranged in the workwear 1. For example, the power supply device 47 can be arranged externally to the workwear 1 in a component 5 of the welding system 3 or a device 53 which are connected to the remote controller 4 via interfaces 32 and 48, respectively. Likewise, it is possible for the energy supply device 47 to be arranged or integrated in the work clothing 1 for forming the signal transmission system and for the remote control 4 to be detachably detachably connected to the energy supply device 47 and / or fastened to the work clothing 1. Modules that are structurally separate from the remote controller 4 can be electrically connected to the remote controller 4 via the interfaces 32, 48 or coupling elements 80 (see FIG. 6). Such embodiments are described later.

4 and 5 show a portion of the workwear 1, in particular a sleeve 54 of a top shirt 55 (see Fig. 2), which has a possible embodiment of the remote controller 4.

The workwear 1 has for holding or positioning of the remote controller 4, one or more receiving arrangements 56, where the remote controller 4 is received and attached. As best seen in Fig. 5, the receiving assembly 56 may be formed, for example, in the manner of a receiving pocket 57 in the inner lining of the workwear 1, which forms a receiving chamber 58 between an inner surface 59 of the workwear 1 and a boundary surface 60 of an inner layer 61. The remote controller 4 thus extends between an outer cover layer 62 of the workwear 1 and a preferably textile inner layer 61 attached to the cover layer 62. However, it is also possible for the inner layer 61 to be made of a rigid or hard-to-deform plate, for example of plastic, aluminum etc. exists. In a connecting region 63, the inner layer 61 is attached to the cover layer 62, wherein this attachment by means of connection methods, such as textile sewing, gluing, etc., may be durable, or this connection be releasably formed by means of Velcro, button or the like can.

Another possibility of integrating the remote controller 4 in the workwear 1 is that in the manufacture of workwear 1, the tracks of the transmission system 42, and individual modules of the remote controller 4 are permanently embedded so that they form part of the cover layer 62 of the workwear 1. In the case of textile material, this can be done, for example, by weaving in, for plastic clothing by material wrapping during the manufacturing process.

In the embodiment variant of a remote controller 4 illustrated in FIGS. 4 and 5, the latter has a printed circuit board 64 with the electrical transmission system 42, via which at least some modules of the remote controller 4, for example the setting members 30, the output devices 31, the interface 32 and the power supply device 47 connected to each other. Furthermore, it is possible for the printed circuit board 64 to be connected via the transmission system 42 to the control device 44, in particular a microcontroller 45 and the memory device 46, at connection positions, with the microcontroller 45 and the memory device 1 1 AT 503 678 B1 46 serving as separate components for this purpose , which are connected via contacts with the circuit board 64 may be formed. Another known from the prior art configuration of microcontrollers 45 is that the integrated circuits of the microcontroller 45 are formed directly on the circuit board 64, so the microcontroller 45 and the memory device 46 forms a part of the circuit board 64. For this purpose, the printed circuit board 64 is preferably made of a flexible material, such as a polymeric plastic, and in the form of a film, which is provided by a known from the prior art method with the integrated circuits of a microprocessor or printed, so components of electronic devices are integrated in such a polymeric plastic film. It may be further equipped with a display 65, the circuit board 64, this display is again connected as a separate component to the circuit board 64 via contacts or embedded in the circuit board 64 by integration into this, for example, as a flexible liquid crystal display or the like. Is formed. The person working in the field of electronics or integration of electronic components specialist are printed circuit boards 64, which are designed as multifunctional plastic films and in addition to microprocessors or microchips and transmitter or. Receiving antennas, coils, sensors, batteries, etc. may contain known, so this is not discussed here at this point.

By such a flexible circuit board 64 in this integrated modules of the remote controller 4, the wearing comfort of a work wear 1 for a user 2 is not or only slightly impaired and it may also be a cleaning of workwear 1, for example, a wet cleaning by means of a washing machine or dry cleaning by scrubbing or the like. Can be made without the remote controller 4 is damaged by mechanical stress or parts thereof to break.

Furthermore, at least the actuation areas 66 or display areas 67 of the operating device 29 can be freely accessible or freely visible on an outer surface 68 of the work clothing 1. For this purpose, in the operating or display areas 66, 67, the covering layer 62 of the workwear 1 can be formed partially transparent or transparent so that insight is provided on a display surface 70 and / or actuating surfaces 71 of the dispensing device 31 and / or adjusting elements 30 disposed within the workwear 1 can be taken. The transparent or transparent regions 72 of the cover layer 62 within the cutout 69 may be closed by a protective cover 73, which is preferably formed of a transparent and deformable or flexible material, in particular of plastic. Thus, can be viewed at least over subregions on the inside of the workwear 1 remote control 4, wherein the remote control 4 is also protected from external influences.

Furthermore, it is possible, in particular in the actuation region 66 of the setting members 30, for the cover layer 62 to extend unchanged, for example opaque, over it, but identifications 74 substantially congruent with the adjustment elements 30 arranged on the inner surface 59 on the outer surface 68 of the cover layer 62 attached or applied, for example, printed, glued, sewn, etc., are. These markings 74 preferably have a function-related appearance, e.g. a symbol, an abbreviation, a wording, to the lying below these adjustment members 30, so that an operator, for example with a finger 75, can easily operate the desired adjustment member 30, from which the corresponding control functions or commands for the welding system. 3 to generate.

To the operating device 29, comprising the adjusting members 30 and the output device 31 should be noted at this point that they realized in the form of a one-piece input and / or output unit in the form of a single element, in particular a so-called touch-screen or similar device can be.

The power supply device 47 shown in FIG. 4 is in the embodiment shown play independently in the form of a battery 76 which is connected via lines 77, 78 to the circuit board 64, for which purpose a not shown voltage converter means for providing the On the circuit board 64 necessary operating voltage in the lines 77, 78 may be connected or may be arranged in the circuit board 64. The battery 76 is preferably interchangeably disposed in the workwear, i. Removable or replaceable from the receiving assembly 56 or is permanently and electrically rechargeable integrated in the work clothes 1. In this context, it is expedient to provide a charge level indicator of the power supply device 47 in the remote controller 4, wherein such a charge level indicator can be implemented on the output device 31, so that a person 2 may possibly gain knowledge of a necessary change of the battery 56 by reading the charge level indicator.

The interface 32 is also arranged in the embodiment shown in a separate receiving device 56, which of course can be integrated in the circuit board 64, as described above. The transmission element 40 of the interface 32 is designed as a wireless transmitting and / or receiving device or as a transmitter / receiver, for example for a radio transmission by means of RFID (Radio Frequency Identification) or RF frequencies, with a wireless unidirectional or bidirectional Communication with a component 5, in particular interface 35, the welding system 3 is feasible and which is connected to the circuit board 64 for electrical signal transmission.

As a result, it is now possible for the remote controller 4 on the one hand to be able to determine specific parameters or settings of a welding system 3 and, on the other hand, to monitor one or more parameters of a welding process. The monitoring of a welding process can be done by visualizing the welding system settings on the display 65 of the control device 29 during a running welding process. For example, it is possible for a person to carry out a manual welding process by hand, whereby by arranging the operating device 29 in the region of one hand of the respective person 2, for example on a back of the hand or a forearm of a sleeve 54, ie in the field of vision of a person 2 in the region of Welding point or the welding torch 14, the parameters can be read and entered by the person 2 without significant impairment of the workflow or attention to the welding process and. This results in the advantage that even during an ongoing, manual hand welding process of the person 2 can be responded to process fluctuations or changes due to interference and these disturbances can be counteracted by readjustment of parameters during the welding process via the control device 29 of the remote controller 4, For this purpose, the welding process does not have to be interrupted in order, as is the case in the prior art, to correct the necessary settings on the welding current source 6 or the setting console 28. According to the invention, a real-time process monitoring can thus be performed by the remote controller 4 integrated in the workwear 1.

By a distributed arrangement of the individual modules of the remote controller 4, as shown in Fig. 4 by individually arranged power supply device 47 and interface 32, individual modules of the remote controller 4 can be exchanged and adapted to the application or different welding systems 3 and 5 components. For example, the operating device 29 and / or the entire transmission system 42 with the modules arranged therein can be detachably fastened to the receiving device 56 of the workwear 1, as shown in FIG. Thus, it is possible that a remote controller 4 or individual modules thereof can be used, which are specially designed for communication with individual types of welding equipment 3 or components 5. For different welding applications can be built or arranged by exchanging the remote controller 4 or individual modules of the same tuned to the welding system used remote controller 4 on the work clothes 1. In such type-specific remote controllers 4, the setting options, which are different for each welding method, may be specially adapted to the welding method provided for the remote controller 4.

Another possibility is that the remote controller 4 performs an automatic configuration of the setting options when used with a special type of welding equipment 3, or this configuration can be set manually by a user. For this purpose, 4 means may be provided in the remote controller, for example a program logic configuration routine stored in the memory device 46, which may be e.g. in the event of coming into effect communication link of the remote controller 4 with the component 5 make a configuration for adjusting the settings by means of the control device 29 of the remote controller 4. Thus, the remote controller 4 may be configured to communicate with different types of welding equipment 3, with only those settings needed for the particular welding process being available. For example, different type definitions or specifications of welding installations 3 or components 5 can be stored in the storage device 46, which are loaded depending on the type of welding system 3 or component 5 that is in communication with the remote controller 4.

Furthermore, it is possible that the remote controller 4 is activated only when this or individual modules thereof is connected to the power supply device 47 or an electrical circuit of the signal transmission system in the workwear 1. A use of the remote controller 4 is thus possible only in conjunction with the workwear 1, which has the signal transmission system.

In the embodiment of Fig. 6, in which the workwear 1 is shown with a detachable from this and connectable with this remote control 4, the remote controller 4 is equipped with a connecting device 79, which is the one for establishing a mechanical coupling with the work clothes 1, in particular with fastening elements of the receiving device 56, is formed. The connecting device 79 is arranged on the outside of the remote controller 4 and provided as shown with fasteners in the manner of a hook and loop fastener, but can also in the manner of a Velcro, Clips-, plug, screw or any known from the prior art device for mechanical coupling of two elements be educated.

In the exemplary embodiment shown, the energy supply device 47 is arranged separately from the remote controller 4 in the workwear 1 and can be electrically connected to a coupling element 80 at the remote control 4 via a further coupling element 81 on the workwear 1 for signal transmission, in particular energy supply of the remote controller 4. Thus, it is possible that the remote controller 4 is connected at connecting the connecting device 79 to the receiving device 56 at the same time via the coupling elements 80, 81 to the power supply device 47 and this is thus preferably activated automatically. For this purpose, the coupling element 80 of the workwear 1 is preferably arranged in the vicinity of the individual fasteners of the receiving device 56, so that by the matching local positioning of the other, corresponding to the first coupling element 80 coupling element 81 of the remote controller 4 in a reliable manner a mechanical coupling for producing an electrical connection effect can be done. The coupling elements 80, 81 may be formed for example by mutually corresponding plug or sockets 81 with electrical contacts for signal transmission.

It should be noted a further possibility, in which the remote controller 4 again has no own power source, but the remote controller 4 electrical energy is supplied from a component 5 arranged in the power supply device 47 via the interface 32, as will be described in the course of FIG.

As a further possible execution detail of a workwear 1 according to FIG. 6, this has a characteristic value transmitter 82, which can be electrically coupled to the remote controller 4, in particular via the coupling elements 80, 81. The characteristic value transmitter 82 has, for example, a microcontroller and a microcontroller a memory device, so that data or parameters in the characteristic value generator 82 via the coupling elements 80, 81 can be stored and retrieved. In addition to electrical power can thus analog or digital information or data sets unidirectional or bidirectional to the remote controller 4 are transferable. In the identifier 82, this may be e.g. welding-specific data from the connected to the interface 32 of the remote controller 4 component 5, such as date, working hours, welding equipment settings or the like are stored and read out. Furthermore, person-specific data may be stored in the characteristic value generator 82, for example in the form of user authorizations or biometric personal data. Expediently, the characteristic value transmitter 82 can be realized by a transponder 83, which is preferably formed on a flexible film and has a friend-fed energy supply, which is known in the prior art.

The arrangement of a transponder 83 in the workwear 4 is advantageous because in the memory different information or parameters can be stored and, if necessary, retrievable, so that the workwear 1 has an integrated, insensitive and reliable information carrier. The transponder 83 has a very small size and a flat and deformable or flexible structure. For the construction of the transponder 83, it should be noted that this can consist of a flexible film with integrated microcontroller, memory device, and interface in it and can have a size and an areal extent of a few mm 2 to several cm 2.

Furthermore, a mobile telephone 89 is shown in FIG. 6 as a device 53, that communicates with the remote control 4 via the communication device 48. For this purpose, the communication device 48 is preferably provided as a standardized interface, for example a Bluetooth, WLAN, interface, whereby a signal exchange is made possible with a multiplicity of different types of devices 53. For example, the mobile phone 89 may be used in the manner of a modem for establishing a communication connection with the public communication network 52 (see FIG. 3), whereby the status or process of a welding plant or a welding process can be determined by a data processing system connected to the communication network 52 and / or the data stored in the transponder 83 are retrievable, whereby it is also possible for a connection to the communication network 52 to be established directly via the communication device 48.

In Fig. 7 and 8, a further embodiment is shown in which a transmission of electrical power or information wirelessly via an electrical coupling of the remote controller 4 and the component 5 by means of the transmission elements 40, 84 of the interface 32 and interface 35 takes place.

The transmission elements 40, 84 are formed for example by a primary-side excitation element 85 and a secondary-side induction element 86, which are mutually magnetically coupled. In this case, the energy supply device 47 can be assigned to the component 5, for example the welding torch 14, and is connected to the transmission element 84 in an electrically conductive manner. Expediently, the excitation element 85 and the induction element 86 are provided as electric coils, so that a magnetic field is built up by the current flow in the excitation element 85, whereby a voltage in the induction element 86 can be induced when the induction element 86 is positioned in this exciter field, as can be seen in FIG the prior art in transformer circuits is known. Via the power supply device 47, by controlling a primary-side manipulated variable, e.g. a frequency at the excitation element 85, the voltage on the induction element 86 are set or regulated. It should be noted that the primary-side excitation element 85 can also be assigned to the remote controller 4 and the secondary-side induction element 86 of the component 5 can be assigned or a switchover of the primary and secondary sides is made to allow in the opposite direction signal transmission. 15 AT 503 678 B1

Such a construction is advantageous since, when the welding torch 14 is gripped by the person 2 with the glove 88, the magnetic coupling between the interfaces 32, 35 automatically comes into force.

According to the embodiment shown in FIGS. 7 and 8, the remote control 4 can extend over several work clothes 1 or separate garments, in particular the glove 88 and the outer shirt 55, which are worn by a user 2. The signal transmission between the different pieces of workwear 1 can be done by wires or wirelessly by lines, for which purpose all already mentioned in other connexion transfer method can be used. Furthermore, it is possible for the remote controller 4 to be associated with a rechargeable energy store, for example a capacitor or accumulator, which is connected to the transfer element 40. The energy storage is expediently charged in existing active connection between the two transmission elements 40, 84 by the power provided by the energy supply device 47 of the component 5 energy, so that the remote control 4 supplies even with separate electrical coupling with the interface 35 of the component 5 with the energy stored in the energy storage can be.

It is now a system particularly advantageous that composed of the induction element 86 of the glove 88 and provided as a welding torch 14 component 5 with the excitation element 85, since in a manual welding process by a person 2, the inner glove area on a handle 87 of the welding torch fourteenth is applied, as can be seen from the illustration in Fig. 8. If the excitation element 85 is now arranged in this region of the grip piece 87 and if this is actively connected to the energy supply device 47, then it can be fed wirelessly into the remote control 4 via induction, energy, whereby coupling methods known to the person skilled in the art also include an inductive information transmission, for example, by modulation of the transmitted voltages, is possible. The energy supply device 47 is powered, for example, via the welding energy contained in the welding torch 14 via the potentials of the welding power source or separate power supply lines, so that no additional or self-sufficient voltage sources are required to operate the remote controller 4.

With the interface 35 of the component 5 and / or the interface 32 of the remote controller 4, a signal processing means can further be functionally connected, which is designed for the transmission or analog processing of information, for example in the manner of a modulation / demodulation means. The exact mode of operation of an inductive power or information transmission via an excitation or induction element 85, 86, which can take place unidirectionally or bidirectionally, is known to the person skilled in the art in this field.

According to the embodiments according to FIGS. 6 to 8, it is thus possible for the data transmitted by the component 5 of a welding system 3 to the remote controller 4 to be stored in the characteristic value transmitter 82 and / or the memory device 46 of the remote controller 4, whereby a logging on or off several definable parameters can be made. For example, it is also possible for user authorizations to be stored or stored as data in the characteristic value transmitter 82 or the memory device 46 of the remote controller 4, these user authorizations being the actual use of a welding system 3, the permission for carrying out different welding programs or welding system settings, etc. may include, so for example only released settings on the component 5 of the welding system 3 can be made via the remote controller 4. Thus, it is possible that with work clothes 1 and 4 remote controllers are assigned to certain persons or users, only those welding work can be performed for which there is an authorization. In one possible refinement, biometric data of a person 2 can be stored in the characteristic value transmitter 82 or remote controller 4, so that only welding work can be carried out for one person if the latter carries the welding clothing assigned to it with the corresponding biometric data stored in it corresponding biometric identification means for persons may include 1 6 AT 503 678 B1.

FIG. 9 shows a further embodiment variant of the remote controller 4, in which case one or more energy converters 90 are provided as the energy supply device 47, the remote controller 4 being of batteryless design. As energy converter 90, for example, thermoelectric or electromechanical elements, such as Peltier, piezoelectric elements, etc., can be used. As shown, with at least one of the adjusters 30, the energy converter 90 may be operatively connected, as shown in FIG. 9 via a mechanical pressure element 91, and the energy converter 90 is formed by an electromechanical transducer element, such as a piezo element, i. a material deformation is converted by an acting force into electrical energy. If the adjusting member 30 is actuated, a mechanical deformation of the electromechanical element of the energy converter 90, whereby electrical energy is generated by this and the transmission system 42 is provided. Thus, electrical control commands can be sent via the interface 32 upon actuation of the adjusting members 30. For a thermoelectric element, e.g. a Peltier element, as an energy converter 90, the generation of energy for the operation of the remote controller 4 by the body's waste heat of the person 2, which wears the work clothes 1 done, whereby a constant power generation is possible. Further examples of integration options of the remote controller 4 in a workwear 1 are represented by a pair of glasses 92, as well as a shoe 93.

The different components 5 of the welding installation 3, for example welding power source 6, welding torch 14, input and / or output device 26, etc., can be the subject of an independent solution according to the invention. For this purpose, the components 5 are equipped with the interface 35, which is designed to produce an electrical connection, in particular signal or data transmission or power transmission, with the interface 32 of the remote controller 4 of the workwear 1.

An independent solution also relates to a system for controlling and / or regulating welding systems 3, the system comprising the workwear 1, to which the remote control 4 is assigned, and at least one of the components 5 of the welding system 3. For this purpose, the remote controller 4 has the interface 32 and the component 5 has the interface 35 for establishing an electrical connection with the remote control 4. Thus, electrical signals, in particular a power and / or information or data sets, can be transmitted between the interfaces 32, 35 of the system.

Of course, it is possible that the remote controller 4 is arranged not only at one point of the workwear 1, but that a plurality of remote control 4, in particular for different types of welding equipment 3, are arranged at different locations or areas of workwear 1.

The embodiments show possible embodiments of the workwear 1, the remote controller 4, the components 5, and a system for controlling and / or regulating welding systems 3, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various combinations of the individual variants are possible with each other and this possibility of variation due to the doctrine of technical action by objective invention in the skill of those working in this technical field is the expert. There are therefore also all possible embodiments, which are possible by combinations of individual details of the illustrated and described embodiment, the scope of protection.

FIG. 9 shows an independent solution for a workwear 1. It is this workwear 1 suitable for welding work, in which the welding process is carried out by means of electrical energy, i. in which a welding current and a welding voltage flow via the electric welding lines 21, 22 1 7 AT 503 678 B1 for igniting an arc 19. This is in electrical resistance welding processes, such as e.g. Stick, MIG / MAG or TIG welding is the case.

As is known as general physical law, current and voltage-carrying conductors emit an electric and magnetic field, with the voltage as the governing quantity for the electric field and the current intensity in the conductor as the decisive quantity for the magnetic field. In welding processes performed by welding systems 3, low-frequency electric and magnetic fields mainly occur around the current-carrying lines, which are in a frequency range of 0 to 30 kHz according to the frequency of the welding current, whereby high-frequency electromagnetic waves in the range of 30 kHz to approx. 1 MHz can be sent out. In the low-frequency range for the person 2 in the area of the welding system 3, the time-varying, magnetic field for the effect on the body is relevant, since this can not be shielded with known from the prior art clothing materials in the field of work wear.

With the work clothing 1 according to the invention for welding work, an effect of the electrical and in particular the magnetic fields on the human body can be reduced or prevented.

For this purpose, the workwear 1 has one or more protection zones 127, in which a protective device 128 is arranged or effective, with the shielding or reduction of electrical and / or by a current-carrying component 5 of the welding system 3, for example, the welding lines 21, 22, electrical / / or magnetic fields in the particular behind the protection zones 127 lying areas or an interior 129 of the work clothes 1 takes place. Due to the arranged protective device 128, the shielding of the work clothing 1 surrounded by the interior 129, in which the corresponding parts of the body of the person 2 are, against magnetic and / or electrical DC or alternating fields possible.

In Fig. 9 as an example of a workwear 1, a welding overalls 130 is shown, which may be formed in one or more parts and - simplified represented by dashed lines - the protection zones 127 in a trunk area 131, a sleeve portion 132 and a hip or. Lumbar region 133 has. The areas 131 to 133 represent for a person 2 at many welding positions by direct proximity to the current-carrying welding lines 21, 22 the body parts most strongly influenced by the magnetic field generated by the electric welding energy, at least for weakening the field strength of the field acting on the person 2 be shielded or protected by the protective devices 128. Of course, it is also possible that extends over the entire extent or any other areas of workwear 1, the protection zone 127 with arranged in this or effective protection device 128. For example, the protection zones 127 can also be located in the spine or back, head or hand covering areas of workwear 1, wherein the protection zone 127 may extend in particular in the region of the human central nervous system.

The protective device 128 may be formed by an electrically and / or magnetic radiation insulating or dissipative, passively effective shielding element 134, as shown in FIGS. 9 to 11 can be seen. The shielding element 134 is formed by a material which causes a shielding of low-frequency electrical and / or magnetic fields and / or high-frequency electromagnetic waves - hereinafter referred to simply as "fields" for simplicity - so that the interior 129 of the workwear 1 in front of fields is protected.

As can be seen from FIGS. 10 and 11, the shielding element 134 can be formed by a flat surface

Shielding layer 135 may be formed, which is arranged in the protection zone 127. It is a plate, strip or foil-like design of Schirmungslage 135 possible. The shielding layer 135 may, in conjunction with further clothing material 136 of the workwear 1, for example textile fabric or lining, form the protection zone 127, or the shielding layer 135 alone forms the workwear 1 in the area of the protection zone 127.

In Fig. 10 is a tubular, the interior 129 fully enclosing Schirmungslage 135 is shown, which may optionally be formed by a plurality of shell parts. With such an embodiment of the shielding layer 135 enclosing the interior 129, an additional effect according to the principle of a Faraday cage can be achieved, so that the interior 129 is shielded at least from high-frequency, electromagnetic radiation. The shielding layer 135 may surround the interior 129 in preferred embodiments in the trunk area 131 or chest and abdominal area or in the hip or lumbar area 132 in a horizontally extending extension plane. The shielding layer 135 is preferably adapted to the anatomy of the person 2 in the area of the protection zone 127.

Along its main plane of extension, the shielding layer 135 can be closed in itself or made of solid material, or structured, for example, grid or hole plate-like, and for this purpose have one or more openings or recesses. By means of the shielding layers 135, which are either closed or open, the interfering fields can be attenuated or derived depending on their properties, in particular the frequency. A shielding layer 135 designed as a closed solid body is particularly suitable for shielding low-frequency, magnetic fields, wherein the shielding layer 135 for this purpose is preferably formed from magnetically conductive or highly permeable material. A structured shielding layer 135, in particular a perforated or grid plate, is suitable here for shielding high-frequency or electric fields by the operating principle of a Faraday cage, wherein the structured shielding layer 135 can likewise be formed from magnetically conductive or high-permeability material.

The shielding layer 135 is arranged according to the example in the manner of an input or intermediate layer in the protection zone 127 and completely surrounded by the clothing material 136 or embedded in this. In this case, the shielding layer 135 may be permanently sewn into the clothing material 136 or arranged in an accessible holding pocket of the workwear 1 and may be removable via a slot-like access opening, for example.

Another possibility of an embodiment of the shielding element 134 is that this is applied to the clothing material 136 of the workwear 1 in the protection zone 127 as a coating 137, as shown in FIG. 12. The coating 137 can be applied either to an outer surface 138 or to an inner surface 139 of the work clothing 1 or the garment. The shielding element 134 embodied as a coating 137 facilitates the production of the workwear 1 in the area of the protection zone 127, since the shielding element 134 does not have to be embedded in the clothing material 136, but via a coating method known externally or internally from the state of the art Materials 136 is applied. An attachment of the Schirmungselements 134 on the outer surface 138 or inner surface 139 of the work clothes 1 can also be done by an adhesive or plastic welding connection.

A further possibility of an embodiment of the shielding element 134 is shown in FIG. 13, wherein the shielding element 134 is formed by a braid or fabric 140, which comprises at least partially electrically and / or magnetically shielding properties having fibers 141. The braid or fabric 140 is preferably designed to be flexible or adaptable, so that for the person 2 the wearing comfort of textile-based work clothing lying on the body is not or only insignificantly restricted. 1 9 AT 503 678 B1

A further embodiment of a workwear 1 is shown in Fig. 14, wherein an 8e-fastening device 142, in particular a Velcro connection, is arranged on the outer surface 138, via which the Schirmungselement 134 on the outer surface 138 is releasably or permanently attached. The fastening device 142 can of course also be provided on the inner surface 139 in the workwear 1, so that the shielding element 134 can be fastened on the inside. The shielding element 134 is formed as a cloth or flap-like cover element, which is optionally formed as a separate and completely detachable from the protection zone 127 component. The fastening device 142 can consist of individual connecting elements 143 assigned to the outer or inner surface 138, 139 and further connecting elements 144 assigned to the shielding element 134, wherein the connecting elements 143, 144 are designed to produce a mechanical coupling. For example, the connecting elements 143, 144 are represented by a hook-and-loop fastener or clips or plug-in elements or the like.

In general, it should be noted for the shielding element 134 that this, in particular the shielding layer 135 or the shielding fibers 141 of the fabric 140, is formed at least in part from a material which has magnetic or / or electric field shielding or dissipative properties. For shielding of magnetic fields, the material is preferably selected from the group of ferromagnetic materials and it has a high permeability, in particular greater than 1, and preferably soft magnetic properties. Such materials are known from the prior art, for example, soft magnetic iron-nickel alloys, such as an 80% iron sen-nickel alloy, the so-called MU metal, can be used as a material for the shielding element 134. As further materials for the shielding element 134, non-magnetic materials, e.g. Copper, aluminum or the like may be used, wherein a possible embodiment is noted, in which a Schirmungselement 134 several Schirmungslagen 135 are provided, which are each made of different materials, such as ferromagnetic and non-ferromagnetic materials.

Furthermore, there is the possibility that in the protection zone 127, the shielding element 134 is enclosed by refractory or heat-resistant or UV-resistant clothing material 136 or incorporated therein. Thus, the heating of the Schirmungselements 134, which is optionally formed of ferromagnetic material, over the Curie temperature of about 768 ° C for iron and at about 158 ° C for nickel can be prevented, so that the ferromagnetic properties are not lost in the material ,

The shielding element 134 can furthermore be connected to a grounding line 145, for example via a pluggable connection or the like, so that a dissipation of the optionally prevailing electricity in the shielding element 134 can take place. For this purpose, it should be noted that different shielding elements 134 may be conductively connected to one another and optionally at least one of the shielding elements 134 is connected to the grounding line 145.

Another embodiment of the protective device 128 is that it has a compensator 146 for the active compensation of fields, in particular magnetic fields, or radiation, as shown in FIG. 15.

The compensator 146 is designed for canceling or reducing preferably magnetic fields (Hs) of the welding system 3 by segregation of compensation fields (HK) directed counter to these. As is known physically, in particular the vectorial magnitude of the magnetic field strength at any point in space can be reduced by precisely oppositely acting field strength or canceled out at exactly the same amount of field strength, exploiting this principle by means of active generation of opposing magnetic fields by compensator 146 becomes. 20 AT 503 678 B1

The compensator 146 has for this purpose a field generator 147, which is designed to generate electrical and / or magnetic opposing fields, whereby the fields generated by components 5 of the welding system 3 are at least partially canceled or compensated. The field generator 147 may be e.g. be formed as connected to a power source or an electrical supply source electrical conductor 148.

For example, in FIG. 15, the electrical conductor 148 is designed as an annular coil 149, which is arranged in the clothing material 136 of the workwear 1 in the protection zone 127. The conductor 148 is connected via lines 150, 151 to a separate power source 152 or the power source 6 of the welding system 3. The illustrated field lines HK of the generated magnetic field of the conductor 148 are opposite to the field lines of the magnetic field Hs of the welding system 3, so that a weakening or extinction of the magnetic field Hs generated by the welding system 3 in the protection zone 127 of the workwear 1 takes place. The electrical conductor 148, which is connected to the current source 152, is traversed by a compensation current, which preferably has an equal frequency to the welding current, but flows in the opposite direction or has a 180 ° phase-shifted period to the welding current. Thus, an opposing field generated by the field generator 147 to the field of the welding system 3 is always effective. The power source 6; 152 is for this purpose preferably designed to generate a controllable or controllable compensation current in its properties.

A further independent solution according to the invention relates to a welding installation 3, in particular a welding apparatus, or a workwear 1 for welding work that can be carried out via the welding installation 3, wherein this workwear 1 has an analysis unit 227 which has one or more for the detection and / or evaluation Parameter or state variables of the environmental conditions in the field of welding system 3 is formed.

The environmental parameters are measurable state variables or factors of the free environment or environment, in particular in the area of the welding system 3 or in the interior of the workwear 1. Environmental parameters can be, for example, a gas composition or air composition, a temperature, a sound level, a moisture level, an electromagnetic radiation or magnetic and electric field, suspended particles, etc. By means of the analysis device 227, it is possible to detect one or more of the environmental parameters, an evaluation of the environmental parameters with regard to the exceeding of a limit value or with regard to an impermissible composition or concentration, in particular a gas composition, and an output of a control signal as a function of actual values of the To perform environmental parameters.

It has the analysis device 227 at least one sensor 228, which is designed to detect one or more of the environmental parameters in a detection area 229 in the space of the welding system 3.

FIG. 16 shows a person 2 operating the welding system 3 who wears a protective screen 230 for protecting the field of vision as work clothing 1 and a welding overalls 231 which possibly covers several parts and covers the torso and the limbs of the person 2.
