Abstract

PURPOSE:To provide a remote controller for welding which enables the fine adjustment of welding conditions by the welding operator himself during arc generation, by constituting the same in such a way that the operations for storage and regeneration of the welding conditions are centrally controlled near the arc welding operation as far as possible, that is, by the remote controller for welding machine. CONSTITUTION:When a power source is turned on, a control section 8 checks an input section 5 and executes prescribed operations according to operation buttons. More specifically, the control section drives a storage section 9 for welding conditions and stores the values of the welding current and voltage displayed presently on a display section 11 into the assigned storage address, when the storage for conditions is commanded. In the stage of regenerating the conditions, the control section calls out the values of the welding current and voltage in the assigned storage addresses similarly and outputs the same to an output section 12 for the set reference voltage through an output interface section 10. When the signal from a reception section 13 is inputted to the control section, the control section changes the display value corresponding to the section 11 according to said signal value and changes simultaneously the output signal to the output section 12. The section 8 checks the power source section for holding the storage for conditions in addition to the above-mentioned control operations, judges the consumption of the power source and displays the presence or absence of the abnormality in the welding power source body in the section 12 through the section 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote controller for welding, and more particularly, a remote controller for bath welding for adjusting welding conditions at a position away from the welding power source body, that is, near the arc welding operation. It is related to vessels.

FIG. 1 shows a typical configuration of a conventional semi-automatic arc welder using a consumable electrode, specifically a bath welding wire. In the figure, 1 is the welding power source main body, and the output from this power source main body, that is, the bath current and welding voltage, are remote? Ij! l
It is adjusted by a current setting knob 3 and a pressure setting pot knob 4 provided on the sea bream jig 2. Said current setting knob 3
As shown in the figure, the voltage setting knob 4 may be a dial type or a digital switch.

In any case, when working with at least two or more construction conditions depending on the object to be contacted with the bath, even though one of the conditions is desired, it is necessary to change the conditions to the other. It is necessary to change the setting value of the adjustment element, ie, the welding current or welding voltage, and each time the conditions change, a test arc must be emitted to check for proper welding. As a solution to this problem, it is considered to automate the setting of welding conditions, which the operator had to do each time welding work.One method is to memorize arbitrary welding conditions in advance, and then set the welding conditions as necessary. There are methods such as reproducing the welding conditions and performing welding. However, these functional operations such as memory and playback are concentrated in the welding power source, so if the object to be welded is placed extremely far from the welding power source or placed at a high position, Operability becomes significantly worse. Furthermore, with conventional remote controllers, due to operating constraints during arc welding work, it is necessary to adjust the welding conditions during welding when the welding torch is held in the right hand and the light shield is held in the left hand. It was difficult for people to do it themselves. On the other hand, although there are general construction conditions for welding current values, welding voltage values, etc. depending on the object to be welded, the details are often determined based on the experience or knowledge of the welding operator. Therefore, fine adjustment of the conditions after arc occurrence is not necessary.

The purpose of the present invention is to eliminate the above-mentioned conventional entry point, use a remote silencer to adjust, memorize, and reproduce welding conditions, and also to perform welding operations during arc generation, which was previously considered difficult. It is an object of the present invention to provide a welding remote controller capable of improving bath welding work efficiency by allowing a person to finely adjust welding conditions by himself/herself.

The present invention is based on the idea that, in order to improve welding efficiency, welding condition storage and replay operations are centrally controlled near the hood arc welding operation, that is, by a remote controller for the welding machine.

Furthermore, in view of operational constraints during arc welding work, a wireless remote controller for adjusting the welding strands, which can be operated with one hand, is provided for the welding machine remote controller. This allows the welding operator to adjust the welding conditions during the welding process.

One embodiment of the present invention will be explained below with reference to block diagrams shown in FIGS. 2 and 3. FIG. 2 is a block diagram showing the overall configuration of a remote controller for a welding machine according to the present invention. In FIG. 2, reference numeral 5 indicates an input section composed of, for example, push button switches, 6 indicates an adjustment section that adjusts the input from the input section 5 to a predetermined value, and 7 indicates an adjustment signal from the adjustment section 6. 9 is a storage section for welding conditions, and 10 is a display section 11 for displaying the control section 8 and current, voltage values, etc., and outputting reference voltages for setting the current and voltage. 13 is an output interface section between the voltage output sections 12 and 44 for condition adjustment, which will be described later in FIG. 3.

'Specifying the voltage plate 1. is stored in the address. In the case of condition reproduction, the welding current/voltage values of the designated storage zone are similarly called up and outputted to the set reference voltage output section 12 via the output interface section 10. Furthermore, when a signal from the receiving section 13 is input, the value of the corresponding display value on the display section 11 is changed according to this No. 16 value, and the output No. 16 to the set reference voltage output section 12 is also changed at the same time. In addition to the above-mentioned control operations, the control unit 1 8 also checks the power supply unit for storing the conditions, determines power consumption, and connects the welding unit inside the set reference voltage output unit 12 to the power supply unit. The cable is also checked for disconnection, and the presence or absence of any abnormality is displayed on the display unit 11. The configuration of FIG. 2 can also be realized with a microcomputer. In this case, the central part of the control section 8 in FIG. 2 will be integrated into a microprocessor, and desired processing will be executed under the control of a program, and the storage section 9 will be played by a RAM.

Further, even if the configuration shown in FIG. 2 is provided in the power supply main body or the wire feeding section, the remote controller for fine adjustment of conditions shown in FIG. 3 can be sufficiently applied.

Further, the switch shown in FIG. 5 does not have to be an increase/decrease switch, but may be composed of one or more switches that determine the so-called decrease/decrease.

As explained above, according to this proposal, in addition to checking the welding conditions, it is possible to memorize and perform the welding conditions at hand, and the welding operator can perform the welding process himself while an arc is occurring, which was previously considered difficult. Since it is possible to fine-tune the bath welding conditions, it is possible to easily set the optimal bath welding flexibility according to the object to be welded and the bath welding posture, which not only improves welding work but also improves the quality of the welded part. can also be achieved.
