Description

BACKGROUND

This disclosure relates to a portable electric arc-welding system. A welding machine welds two or more pieces of metals together. To do so requires a significant amount of power. One method used to power a welding system is through an engine. Such method of welding is known as engine-driven welders. Such method makes use of a gasoline, diesel, or propane-fueled engine that can be connected to an electrical generator to produce power for welding. Engine-driven welding system can be effective in producing sufficient power source to be used for arc welding however, there can be situations wherein using such method can cause inconvenience, such as indoor welding. In such scenario, the indoor space should be well ventilated and/or should have a large space since welding fumes produced by engine-driven welding system can cause suffocation. Furthermore, engine-driven welding system can have a lot of parts such as seals, rings, gaskets, alternators, water pumps, cranks, blocks, and many other parts which can fail and may need constant replacement. Such scenario can be time consuming, inconvenient, and costly to the user. As such it would be useful to have a portable electric arc-welding system.
Further, the most common method of housing an arc-welding generator involves enclosing the arc-welding generator within an enclosure. Although housing arc-welding generator within an enclosure can be efficient in protecting the internal parts of arc-welding generator, such enclosure serves little other purpose. One concern of a portable electric arc-welding system is the amount of power needed to run such system. As such, it would be useful to have a solar-powered portable housing capable of powering tools.

Control panel 107 can comprise set of gauges, actuators, buttons, and set of displays that can control and/or indicate measurement of various parameters of arc-welding system 100.
FIG. 2 illustrates an embodiment of housing 101 further comprising a top enclosure 201 and a bottom enclosure 202. Top enclosure 201 and bottom enclosure 202 can each be a casing capable of housing a tool such as a welding machine. In this embodiment, top enclosure 201 can secure internal components of the welding machine such as an electric motor, a governor, a main armature, and an exciter armature. Bottom enclosure 202 can be a casing at the bottom portion of housing 101. Bottom enclosure 202 can house a rechargeable battery. Further in this embodiment, walls 101 a can be capable of covering the entire sides of housing 101. As such, walls 101 a can be used to close top enclosure 201 and bottom enclosure 202.
FIG. 3 illustrates housing 101 with bottom enclosure 202 comprising a slot 301 and a drawer 302. Slot 301 can be an opening at the front surface of bottom enclosure 202 insertable by drawer 302.

In one embodiment, battery 303 can be a rectangular rechargeable battery that can fit snugly within drawer 302. Further in this embodiment, battery 303 can be slidably removable from bottom enclosure 202. As such when battery 303 needs replacing, a user can slidably move drawer 202 out of slot 201, then take out and replace battery 303 with a new battery 303.
Further in this embodiment, battery 303 can provide enough power to operate arc-welding system 100. In a preferred embodiment, battery 303 is 10 kWh or more. Further, battery 303 in a preferred embodiment is rechargeable. In another embodiment, battery 303 can be recharged through solar panels 108. In such embodiment, solar panels 103 can be connectable to battery 303. Solar panels 108 can convert ultraviolet radiation from sunlight into useable energy. Solar panels 108 can be used for generating electricity and can be used to provide power source for the rechargeable battery of arc-welding system 100. Solar panels 108 can be placed around the outer surface of housing 101 to ensure that solar panels 108 can absorb enough energy to power welding system 100.
FIG. 4 illustrates a back view of housing 101 comprising a plug 401. In a preferred embodiment, plug 401 can be placed at the bottom edge of back wall 103. Such embodiment can allow plug 401 be more accessible. Moreover, such placement of plug 401 can provide clearance at the back of welding system 100 that can be used to accommodate other devices that can be placed on a truck bed. Plug 401 can allow battery 303 be charged through an electric power source. Once recharged, battery 303 can be capable of powering up arc-welding system 100. Additionally, battery 303 can be charged by solar panels 108. Further, placement of solar panels 108 around the outer surface of arc-welding system 100 can maximize energy retention and optimize energy transfer efficiency of battery 303. In such embodiment, welding system 100 can be used even when an electric power source may not be available. Moreover, rechargeable battery 303 can allow welding system 100 to be used and transportable to locations without a local power source.
FIG. 5 illustrates control panel 107 of arc-welding system 100. In this embodiment, control panel 107 can be placed at the outer surface of front wall 102. In one embodiment, control panel 107 can comprise an amp range selector 501, a fine current selector 502, and an rpm dial 503. Amp range selector 501 can allow the user to select a current within a current range to use for welding. Fine current selector 502 can allow the user to select control of the arc characteristics. Rpm dial 503 can be used to fine-tune the rpms (revolutions per minute) of the motor. As such, RPM dial can adjust rpms of the electric motor. Further in one embodiment, control panel 107 can further comprise a power button 504. Power button 504 can allow arc-welding system 100 to be turned on and or off. In one embodiment power button 504 can be a switch.
FIG. 6A illustrates internal components of arc-welding system 100. In one embodiment, arc-welding system 100 can comprise a welding machine 600 connected to battery 303. For purposes of this disclosure, welding machine 600 can be an electric arc welding machine that can be used to weld metals by generating sufficient heat to soften metals to connect them together. Welding machine 600 can comprise a shaft 601, an electric motor 602, a governor 603, a main armature 604, and/or an exciter armature 605. Electric motor 602 and governor 603 can be connected to battery 303.
FIG. 6B illustrates a block diagram of welding machine 600 powered by battery 303. In a preferred embodiment, electric motor 602 can be a direct-current (DC) motor. Electric motor 602 can convert electrical energy from battery 303 into a rotatable mechanical energy. Electric motor 602 can be driven by governor 603 and can range between 900 and 3600 RPM in a preferred embodiment. As such, governor 603 can regulate the speed of electric motor 602. Shaft 601 can then transfer the rotatable mechanical energy from electric motor 602 to main armature 604. Thus, electric motor 602 can turn main armature 604 and/or exciter armature 605. Main armature 604 can receive the rotatable mechanical energy from electric motor 602 and can produce electrical power. Main armature can provide electrical power for welding, while exciter armature can, in one embodiment receive the rotatable mechanical energy from electric motor 602 and produces electrical power for outlets. Main armature 604 and exciter armature 605 can each deliver single-phase or three-phase alternating current.
Arc-welding system 100 can be used in chemical plants, refineries, pipelines, and other major industries that use rig welders. Further, an example of arc-welding system 100 can be a cross-country welding machine. In one embodiment, arc-welding system 100 can have an intuitive constant current (CC), constant voltage (CV), and can have TIG mode control. In one embodiment, welding system 100 can be capable of dual continuous-controlled output.
For purposes of this disclosure, arc-welding system 100 that runs welding machine 600 generator can have an advantage on how to work the puddle when arc welding. Welding machine 600 can be used to bump the rack and completely change the way welding machine 600 carries metal. A rack can hold brushes for main armature 604. This can allow a user to bump the rack so that welding machine 600 can weld differently, changing the open-circuit voltage (OCV's). As such, RPM dial 503 can be actuated to turn the rpms up or down of electric motor 601 depending on the desired OCVs. Such feature can change the way welding machine 600 can weld to a user's preference. Furthermore governor 603 can also change rpms on welding machine 600 to +/−100 rpms. Moreover, a user of welding machine 600 can change the brushes from 200 s, to 200/300 staggered, or iron stackers, as examples.
In one embodiment wherein arc-welding system 100 can comprise power button 504, turning power button 504 on can allow battery 303 to supply electric power to electric motor 602 which can operate welding machine 600. Concurrently, governor 603 can be powered by battery 303. As such, governor 603 can be used to measure and regulate the speed of the welding machine 600. The electric power transmitted by battery 303 to electric motor 602 can then be converted from electrical energy into mechanical energy. The mechanical energy produced by electrical motor 602 can cause shaft 601 to rotate. Since shaft 601 can connect main armature 604 and exciter armature 605 to electric motor 602, shaft 601 can transmit the energy to main armature 604 and exciter armature 605. Main armature 604 and exciter armature 605 can then transmit a current across the welding machine 600.
FIG. 7A illustrates a block circuit diagram of arc-welding system 100. In this embodiment, arc-welding system 100 can comprise battery 303, an inverter 701, and a transformer 702. Inverter 701 can receive a direct current (DC) from battery 303. Moreover, inverter 701 can convert direct current (DC) voltage from battery 303 to an alternating current (AC) voltage. After receiving DC voltage from battery 303, inverter 701 can then increase DC voltage and changes the DC current to alternating current before sending it to transformer 702. Transformer 702 can receive the AC voltage from inverter 701 then, transformer 702 can be used to either step up or step down the AC voltage while maintaining power at the same level. In this embodiment, transformer 702 can be a dual voltage transformer. As such, transformer 702 can be capable of generating 120 VAC 703 and/or 240 VAC 704 to supply outlets. In this embodiment, electrical energy from battery 303 can be continuously transmitted to welding machine 600, and transformer 702.
FIG. 7B illustrates another block circuit diagram embodiment of arc-welding system 100 further comprising a switch 705. Switch 705 can allow the flow of electric energy from battery 303 be transmitted to either welding machine 600 or transformer 702. In such embodiment, when switch 705 is in a first position, the electric energy from battery 303 can be transmitted to inverter 701 and no electrical energy is transmitted to welding machine 600. Inverter 701 can then convert DC into AC and transmit the energy to transformer 702 and subsequently 120 VAC 703 and/or 240 VAC 704 to supply outlets. Transformer 702 can then be used to adjust voltage. Conversely, when switch 705 is in a second position, electric energy from battery 303 can be transmitted to welding machine 600 or some other tool in housing 101, allowing the machine to operate. Welding machine 600 or some other tool can connect to power from transformer 702 by any way known in the art, including through an outlet inside or outside housing 101, or hardwiring. In such state, no electrical energy is transmitted from battery 303 to transformer 702.
FIG. 8 illustrates an embodiment of housing 101 comprising one or more slideable walls 801. Slideable walls 801 can be a flat structure that encloses the internal section of housing 101. In one embodiment, slideable wall 801 can attach to back wall 103. In a preferred embodiment, slideable walls 801 can attach at opposite sides of housing 101. In this embodiment, slideable walls 801 can comprise a first slideable wall 801 a, and a second slideable wall 801 b. First slideable wall 801 a can be mounted to one side of housing 101, while second slideable wall 801 b can be mounted to a second side of housing 101. As such, second slideable wall 801 b can be placed at the opposite side of first slideable wall 801 a. In such embodiments, each solar panel 108 can mount the inner surface of each slideable wall 801 a and 801 b. As such, in a close position, solar panels 108 can face an interior of housing 101. Moreover, when slideable walls 801 can be in an open position, solar panels 108 at the inner surfaces of each slideable wall 801 can face away from the interior of housing 101. Furthermore, slideable wall 801 can slide upwards using a track and guide system and then angled horizontally upward such that solar panels 108 can be facing the sun. Such embodiment can allow slideable walls 801 to be maneuvered upwards without requiring free space around arc-welding system 100. This feature can be useful in cases wherein welding system 100 is placed on a confined space such as the truck bed and surrounded with other tools and devices. Thus, slideable walls 801 can be positioned to face and catch the sunlight without having to remove any tools, devices, and other obstructions around housing 101. Since any obstructions or shading of object can affect the amount of sun light that reaches solar panels 108, having slideable walls 801 can be useful in efficiently positioning solar panels 108 such that solar panels 108 can maximize the amount of solar radiation that the panels can receive.
FIG. 9A illustrates slideable walls 801 attached at the opposite sides of housing 101. In this embodiment, the top edge of each slideable wall 801 can attach to housing 101 through a fastener system that can hold slideable walls 801 in a closed position. In one embodiment, the fastener system can comprise a hook and a latch. In such embodiment, a hook and latch system 900 can ensure that slideable walls 801 are secured to the sides of housing 101. As an exemplary embodiment, one or more hook 901 can attach to the top edge of each slideable wall 801 while one or more latch 902 can attach to the opposite sides of housing 101. Hooks 901 can be attached on slideable wall 801 such that hooks 901 are aligned to each of latches 902 that are attached to housing 101. As such, hooks 901 can be mateable with said latches 902
FIG. 9B illustrates how slideable walls 801 can be maneuvered into a horizontal position. Initially, slideable walls 801 can be unhooked from latches 902 on housing 101. Unhooking frees the upper portion of slideable walls 801, which can allow the user to slidably maneuver slideable walls 801 into a desired horizontal position. In this embodiment, housing 101 can comprise one or more pairs of tracks 903 that can be compatible with one or more pairs of guides 904 that can attach to the opposite bottom edge portions of each slideable wall 801. Tracks 903 can attach vertically to the opposite side of each sidewall 106. Moreover, guides 904 can be slideably fixed within tracks 903. In such structure, slideable walls 801 be slidably maneuvered from the bottom of tracks 903 to the top of tracks 904 in a vertical position. As such, slideable walls 801 can be vertically maneuverable along tracks 903.
FIG. 9C illustrates housing 101 comprising one or more extendable rods 905 at a retracted position 900 a. Extendable rods 905 can be capable of supporting slideable walls 801 in a desired horizontal position. In one embodiment, extendable rods 905 can be telescopically extendable. In such embodiment, each extendable rod 905 can comprise a first member 906, a second member 907 and a lock mechanism 908. First member 906 can be a cylindrical pole that can be maneuverable within second member 907. In such embodiment, a portion of first member 906 can be placed within second member 907 wherein first member 906 can retract and/or extend from second member 907. As such, extendable rods 905 can be positionable in retracted position 900 a, and an extended position. In retracted position 900 a, slideable walls 801 can be at a closed position wherein slideable walls 801 can rest at the opposite sides of housing 101, as shown in FIG. 9A. Further in one embodiment, structure of extendable rods 905 can resemble a telescopic displacement. In one embodiment, the top edges of second member 907 can comprise a plurality of ridges 909, which can be mountable by a lock mechanism 908. In such embodiment, lock mechanism 908 can be rotated, which can tighten the inner diameter of ridges 909 towards first member 906 locking second member 907 at a desired length. As such, lock mechanism 908 can be used to secure first member 906 and second member 907 in an extended and/or retracted position.
FIG. 9D illustrates extendable rods 905 at an extended position 900 b. In extended position 900 b, extendable rods 905 can support slideable walls 801 in open position, wherein slideable walls 801 can be in a horizontal position along with the top surface of top enclosure 201. As such, after the user positioned slideable walls 801 in open position, the user can then adjust the length of extendable rods 905 and then lock extendable rods 905 to keep the desired length. In one embodiment, the bottom end of each extendable rod 905 can attach to the bottom portion of housing 101 while the top end of extendable rod 905 can be connectable to the outer surface of slideable walls 801. In such embodiment, slideable walls 801 can comprise one or more catches 910 that can be mateable with the top end of extendable rod 905. Catches 910 can secure the top end of extendable rod 905 within slideable walls 801.
FIG. 10 illustrates an embodiment of slideable walls 801 positioned horizontally along the top portion of housing 101. In this embodiment, slideable walls 801 can be positioned horizontally and in parallel with top wall 104. Such embodiment can be used when sunlight is directly above welding system 100.
FIG. 11 illustrates an embodiment of slideable walls 801 angled upwards along the top portion of housing 101. Slideable walls 801 can be used to maximize sunlight capturing. In this embodiment, the user can position the angle of each slideable wall 801 such that solar panels 108 can be clear from any obstruction and can receive maximum amount of solar radiation from the sun. In such embodiment, each slideable wall 801 can be independently angled and can be positioned such that solar panels 108 face the sunlight.
