The invention described herein pertains generally to welding equipment, and more particularly to integrating an air compressor into a welding machine.
Frequently, welding is required where supply power may not be readily available. As such, the welding power supply may be an engine driven welding power supply incorporating a generator. The generator may supply power to the welder as well as to other power tools as may be needed on site. As different applications require different versions of welders and power tools, the trailer may be designed to carry one of many different types of welding power supplies.
Traditional welding-type apparatus can be broken into two basic categories. The first category receives operational power from transmission power receptacles, also known as static power. The second is portable or self-sufficient, stand alone welders having internal combustion engines, also known as rotating power. While in many settings conventional static power driven welders are preferred, engine driven welders enable welding-type processes where static power is not available. Rotating power driven welders operate by utilizing power generated from engine operation. As such, engine driven welders and welding-type apparatus allow portability and thus fill an important need.
Static powered welders initiate the weld process by way of a trigger on a hand-held torch or with an electrically charged stick connected to a charged electrode.
Rotating power driven welders operate similarly, as long as the engine is running. If the engine is shut down, there is typically no residual power to create an arc. To once again weld, the engine must be started and run at operational speed to produce the arc. Therefore, it is simply not possible to manually start and stop the engine between each and every break in the welding process. Further, even during longer periods, operators may find it easier to let the engine run because of distance to the engine, a misconception that it is better for the engine, or just out of habit.
In accordance with the present invention, there is provided a welding device that includes at least one of a motor-driven welder assembly including a motor that is a power source for the welding device to perform a welding operation; an air compressor system that generates and stores a portion of compressed air in a reservoir, wherein the air compressor system is powered by at least the motor; a nozzle coupled to a hose that connects to the reservoir for delivery of the portion of compressed air; and a regulator component that is configured to manage an amount of the portion of compressed air stored in the reservoir.
In accordance with the present invention, there is provided a welding system that includes a motor-driven welder assembly including a motor that is a power source for the welding device to perform a welding operation and an internal compartment that houses an air compressor system. The air compressor system includes a reservoir that stores a portion of compressed air, an intake that receives a portion of ambient air, a crankcase with one or more pistons, means for driving the one or more pistons. a hose with a first end and a second end opposite the first end, the first end is coupled to the reservoir, and a a nozzle coupled to the second end for delivery of the portion of compressed air.
In accordance with the present invention, there is provided a welding device that includes at least the following: a trailer incorporating a trailer hitch, a trailer frame, and a payload region; an adjustable stand on a front end of the trailer, wherein the adjustable stand is configured to adjust a height of the front end of the trailer; an engine driven welder secured to the payload region; a motor-driven welder assembly including a motor that is a power source for the engine driven welder to perform a welding operation; an internal compartment that houses an air compressor system; the air compressor system that includes: a reservoir that stores a portion of compressed air, an intake that receives a portion of ambient air, a crankcase with one or more pistons, means for driving the one or more pistons, and means for delivering the portion of compressed air for inflation of a tire or driving a pneumatic device.
These and other objects of this invention will be evident when viewed in light of the drawings, detailed description and appended claims.
The invention may take physical form in certain parts and arrangements of parts, a preferred embodiment of which will be described in detail in the specification and illustrated in the accompanying drawings which form a part hereof, and wherein:
Embodiments of the invention relate to methods and systems that generally relate to an air compressor system integrated into an engine welder. In particular, an air compressor system can be powered by at least a motor of an engine driven welder such that the engine driven welder can provide enhanced capabilities related to use of stored compressed air. The air compressor system can be stored into a portion of a housing of the engine driven welder, wherein the housing is a compartment that allows for concealment of the air compressor system unless needed by a user. The stored compressed air can be utilized, for instance, to drive a pneumatic device or inflate a tire. Further, an adjustment device allows a user setting to specify a target air pressure for delivery of stored compressed air. Moreover, a regulator component can manage an amount of stored compressed air in a reservoir in order to ensure the reservoir of the air compressor system is maintained within a safe pounds per square inch (PSI) range.
The subject innovation can be used with any suitable engine-driven welder, engine-driven welding system, engine-driven welding apparatus, a welding system powered by an engine, a welding system powered by a battery, a welding system powered by an energy storage device, a hybrid welder (e.g., a welding device that includes an engine driven power source and an energy storage device or batter), or a combination thereof. It is to be appreciated that any suitable system, device, or apparatus that can perform a welding operation can be used with the subject innovation and such can be chosen with sound engineering judgment without departing from the intended scope of coverage of the embodiments of the subject invention. The engine driven welder can include a power source that can be used in a variety of applications where outlet power is not available or when outlet power will not be relied on as the sole source of power including portable power generation, backup power generation, heating, plasma cutting, welding, and gouging. The example discussed herein relates to welding operations, such as, arc welding, plasma cutting, and gouging operations. It is to be appreciated that a power source can generate a portion of power, wherein the portion of power is electrical power. It is to be appreciated that “power source” as used herein can be a motor, an engine, a generator, an energy storage device, a battery, a component that creates electrical power, a component that converts electrical power, or a combination thereof. By way of example and not limitation,
The housing 112 of the welding-type device 100 also houses an internal combustion engine. The engine is evidenced by an exhaust port 130 and a fuel port 132 that protrude through the housing 112. The exhaust port 130 extends above the top panel 122 of the housing 112 and directs exhaust emissions away from the welding-type device 100. The fuel port 132 preferably does not extend beyond the top panel 122 or side panel 124. Such a construction protects the fuel port 132 from damage during transportation and operation of the welding-type device 100.
Referring now to
The welding arc or cutting arc is generated by the power source by conditioning raw power received from an interchangeable energy storage device 226. In a preferred embodiment, energy storage device 226 is a battery. Energy storage device 226 is interchangeable with similarly configured batteries. Specifically, energy storage device 226 is encased in a housing 228. Housing 228 is securable to the housing of welding device 210 thereby forming welding-type apparatus 205. Specifically, energy storage device 226 is secured to power source 210 by way of a fastening means 230. It is contemplated that fastening means 230 may include a clip, locking tab, or other means to allow energy storage device 226 to be repeatedly secured and released from power source 210.
The motor 425 and energy storage device 430 may be operated individually or in tandem to provide electricity for the welding operation and any auxiliary operations performed by hybrid welder 400. For instance, the control between motor 425 and energy storage device 430 can be based upon a switch component (not shown), a controller (not shown), a portion of software, a portion of hardware, or a combination thereof. For example, individual operation may include operating the motor 425 and supplementing the power from the motor 425 with power from the energy storage device 430 on an as needed basis. Or supplying power from the energy storage device 430 alone when the motor 425 is offline. Tandem operation may also include combining power from motor 425 and energy storage device 430 to obtain a desired power output. According to one aspect of the invention, a welder 400 may be provided with a motor having less power output than ordinarily needed, and energy storage device 430 used to supplement the power output to raise it to the desired power output level. In an embodiment, a motor with no more than 19 kW (25 hp) output may be selected and supplemented with six 12 volt batteries. Other combinations of motor output may be used and supplemented with more or less power from energy storage device. The above example, therefore, is not limiting.
Energy storage device 430 may be any alternative power source including a secondary generator, kinetic energy recovery system, or, as shown, one or more batteries 431. In an embodiment, six 12 volt batteries 431 are wired in series to provide power in connection with motor-driven welder assembly 420. Batteries 431 shown are lead acid batteries. Other types of batteries may be used including but not limited to NiCd, molten salt, NiZn, NiMH, Li-ion, gel, dry cell, absorbed glass mat, and the like.

The examples and figures are illustrative only and not meant to limit the invention, which is measured by the scope and spirit of the claims. Referring now to the drawings, wherein the showings are for the purpose of illustrating an exemplary embodiment of the invention only and not for the purpose of limiting same,
Compressor 521 is supported by base 522. In embodiments, base 522 can extend outward from recess 529 to permit easy access to compressor 521 and a secure resting position for compressor 521 when not in use. In embodiments where base 522 can extend outward using support system 523. Support system 523 can include drawer-like rails which telescope or nest when transitioning between an open or closed state. In embodiments, base 522 can be extended or retracted through other mechanisms (e.g., swinging out or in) and can be supported through other mechanisms (e.g., hinges, support cables, legs, stops). In embodiments, base 522 can be cantilevered when extended outward, and support system 523 does not extend beyond the outer edge of welder 500.
Compressor 521 is coupled with retractable cord 524. Retractable cord 524 provides electrical power to compressor 521 for operation. In embodiments, retractable cord 524 can be reinforced to resist damage (e.g., fraying, cutting) and permit use of retractable cord 524 as a tether for compressor 521. Retractable cord 524 can pass through cord aperture 525 to a compartment partitioned from recess 529 where the cord can be kept. Retractable cord 524 can have attached thereto a cord stop (not shown in
While air compressor system 520 is shown oriented in a particular area of welder 500, those of skill in the art will appreciate how this orientation is for illustrative purposes only, and that the particular positioning illustrated is only one of many possible configurations under the disclosures here. Further, it is understood that some embodiments of welders may not permit integration of air compressor system 520, due to the location of internal components. Nonetheless, at least one embodiment of welder can be configured to integrate air compressor system 520 as illustrated, and
Further, while compressor 521 is shown with retractable cord 524, it is understood that, in alternative embodiments, retractable cord 524 need not be a component of air compressor system 520, and compressor 521 can be a detached and removed from recess 529 (also referred to as a compartment. For instance, compressor 521 can include an energy storage device (not shown) that allows for removal and detachment from recess 529 for use of a compressor. In another instance, compressor 521 can include a detachable reservoir with hose and nozzle such that the reservoir can include compressed air generated by a power source and then used while being removed and detached from welder 500. In some such embodiments, compressor 521 can include a recharging port that mates with a similar port in base 522. In this way, the self-contained battery of a compressor 521 can be recharged using power from welder 500.
While
Air compressor system 620 can include compressor 621, base 622, and base supports 623. Base 622 may extend out of or retract into the space between the motor and fuel storage to improve access to compressor 621 and/or provide a “table” on which to replace compressor 621. Base 622 can be supported or retained in one or both of extended and retracted positions by base supports 623.
Compressor 621 is powered using electricity provided through retractable cord 624. Retractable cord 624 is stored about cord spool 627, which can be manually wound to spool or unspool retractable cord 624, or be biased (e.g., spring-loaded) to automatically spool slack in retractable cord 624. In embodiments, retractable cord 624 need not pass through a cord aperture, and cord spool 627 can be disposed in a position with no physical separation from other components of air compressor system 620.
Bases 622 and 622′ can include strap, clip, retainer, or other securing member (not pictured) to secure compressor 621/621′ when engaged. When a securing member is engaged, hybrid welder 600 and/or energy storage apparatus 650 can be moved without shifting of compressor 621/621′, and compressor 621/621′ is secure and prevented from falling off base 622/622′.
In addition to components utilized with welding tools, engine driven welder 710 includes opening 729, which stores compressor 721 and associated components. Opening 729 is exposed or enclosed depending on the position of door 730. Door 730 can be hingedly attached or fold in an outward or inward direction. In embodiments, door 730 can slide along rails to be opened outside engine driven welder 710, or can slide into a compartment of engine driven welder 710. In hinged and sliding embodiments, door 730 may include multiple portions (e.g., hingedly connected) that allow the door to assume curvature otherwise change its shape during opening or closing. Door 730 can include door latch 731, which can attach to one of latches 732 and 733 to secure door 730 in an open or closed position. In some embodiments, door latch 731 can include a lock to provide security and prevent unauthorized use or removal of compressor 721.
In an embodiment, compressor 721 is electrically powered by retractable cord 724. Retractable cord 724 passes through a partition via cord aperture 725, whereafter spool 727 (or another cord-retention component) retains excess cord not needed to move compressor 721 to a position where it is utilized. Retractable cord 724 can be used in combination with overextension preventer 726, which is fixed to at least one portion of retractable cord 724 and stops in contact with cord aperture 725 or another component to prevent retractable cord 724 from being overextended and separating from spool 727 or power coupler 728. A distal cord end operatively attaches with power coupler 728, which routes appropriate electrical power to retractable cord 724 to power compressor 721. In embodiments, power coupler 728 can include a converter, inverter, fuse, surge protector, or other components that prevent excess electrical power from being routed to and possibly damaging compressor 721.
Compressor 721 can rest on a base. Base includes at least a stowed position and a usage position. Base can slide, roll, or otherwise be moved out of opening 729 to improve access and function of air compressor system 720. Base tracks can support base in one or both of the stowed position and usage position. In some embodiments, base can be machined, molded, or otherwise shaped to accommodate compressor 721 placed on base in one or more positions.
Compressor 752 can receive ambient air via ambient air intake 750 and convert ambient air into compressed air. In particular, motor 754 can drive (e.g., rotate) crankshaft 760 disposed within crankcase 756 that actuates piston 758. Piston 758 can provide suction to draw in a portion of ambient air via ambient air intake 750 and force or compress the portion of ambient air into reservoir 762, wherein the force and compression generate a portion of compressed air. Compressor 752 transfers the portion of ambient air through air line 764 that is connected to reservoir 762 for storage of the converted ambient air (e.g., compressed air). The stored compressed air can be delivered via a hose or nozzle from reservoir 762.
In an embodiment, a regulator component (not shown) manages am amount of pressure stored in reservoir 762. In particular, motor 754 can be controlled based upon the regulator component. Still further, an adjustment device can be utilized to set a desired air pressure for delivery from reservoir 762. For instance, a particular pounds per square inch (PSI) may be desired by a user for use with inflation of a tire, a pneumatic device (e.g., drill, nailgun, wrench, air sprayer, impact wrench, jackhammer, and the like), among others. In another embodiment, gauge 784 is provided to indicate a pressure reading or amount. For instance, gauge 784 can display a pressure of reservoir 762 or a target pressure for delivery of a portion of stored compressed air.
In an embodiment, air compressor system 720 can be detachable and removable from compartment or recess 729. For instance, air compressor system 720 can be modular such that reservoir 762 can be portable in comparison to welder 710. For instance, a coupling mechanism that includes first connector 766 and second connector 768 can allow air line 764 to couple and de-couple to reservoir 762. It is to be appreciated that coupling mechanism allows for receipt of a portion of ambient air from compressor 752 which is stored and converted to compressed air. Reservoir 762 can be removable from welder 710 without any connections to allow for portability and eventually delivery of compressed air. It is to be appreciated reservoir 762 can include one or more handles (not shown) for ease of portability.
In an embodiment, reservoir 762 can include a valve with one or more channels. For example, the valve can be a “Y” shaped valve. In particular, the valve can include a first channel 770 and a second channel 772, wherein first channel 770 provides delivery of compressed air at a first air pressure (via an adjustment device) and second channel 772 provides delivery of compressed air at a second air pressure (via an adjustment device). Further, each channel can include an adjustment device that regulates air pressure delivered from reservoir 762. For example, first channel 770 can include adjustment device 776 that regulates an air pressure of compressed air delivered from reservoir 762 and second channel 772 can include adjustment device 776 that regulates air pressure of compressed air delivery from reservoir 762. For instance, nozzle 782 can be coupled to hose 780 that receives compressed air from reservoir 762 for delivery. The nozzle 782 can deliver compressed air to a tire, a item that requires inflating, and the like. In another example, pneumatic device 770 can be actuated by compressed air delivered via hose 778 from reservoir 762. It is to be appreciated that various couplings, connectors, fittings, and the like can be utilized with the subject innovation and for the sake of brevity have not been discussed but are intended to be within the scope of the subject disclosure.
Welder system 700 further includes controller that is configured to manage electrical current use. In particular, controller can determine to perform a welding operation with power source 740, an energy storage device, energy generated by motor 754, or a combination thereof. For instance, motor 754 can be used to supplement or replace power source 740 for electrical current used with a welding operation. In another embodiment, controller can determine when compressor 752 and/or motor 754 can be operated based on a parameter. For instance, the parameter can be a switch or a user input. By way of example and not limitation, the parameter can be a switch that allows a first setting to activate compressor 752. In the embodiment, the parameter is at least one of a representative of power source 740 of welding system 700 operating, a representative of the welding operation being performed (e.g., welding, brazing, gouging, TIG, etc.), an amount of energy stored in an energy storage device, a fuel amount contained within welding system 700, a cost of a fuel for a motor, a fuel consumption efficiency for welding system 700, a duration of time the motor of welding system 700 operates, a welding parameter (e.g., a voltage, a current, a wire feed speed, a type of weld, a workpiece composition, etc.), and the like.
In another embodiment, controller can determine whether to operate compressor 752 based on a parameter that is a welding parameter. For instance, the welding parameter can be, but is not limited to, a voltage of the welding operation, a current of the welding operation, a portion of a waveform used with the welding operation, a welding schedule parameter (e.g., welding process, wire type, wire size, wire feed speed (WFS), volts, trim, wire feeder to use, feed head to use, among others), a position of a welding tool, a composition of the workpiece on which the welding operation is performed, a position or location of an operator, sensor data (e.g., video camera, image capture, thermal imaging device, heat sensing camera, temperature sensor, among others), an amount of charge stored in energy storage device, a signal from a controller of the welding operation, a signal from a controller associated with welding device, and the like.
In an embodiment, the air compressor system further includes a compressor operable to provide compressed air, and comprising a crankcase and a crankshaft, wherein the crankshaft is disposed in the crankcase and a controller that is configured to power the compressor via the motor based upon at least the regulator component. In an embodiment, a welding device can include an adjustment device that is configured to receive a user setting for a target air pressure for the portion of compressed air stored in the reservoir. In an embodiment, the adjustment device further regulates an air pressure delivered from the reservoir to the hose to the nozzle. In an embodiment, the air pressure delivered from the reservoir to the hose to the nozzle is based upon a pounds per square inch (PSI) for a tire or a pneumatic device.
In an embodiment, a welding device can include an energy storage device that is an additional power source for the welding device to perform the welding operation and a switch component that selects between the energy storage device and the motor. In an embodiment, the air compressor system receives a portion of power from the energy storage device to generate the portion of compressed air in the reservoir. In an embodiment, the air compressor system is powered by the motor or the energy storage device.
In an embodiment, a welding device can include a valve member that includes a first channel for a first portion of compressed air and a second channel for a second portion of air, wherein at least one of the first channel or the second channel include at least one adjustment device to regulate a PSI for delivery of the portion of compressed air via the nozzle. In an embodiment, the first portion of compressed air is a first PSI and the second portion of compressed air is a second PSI. In an embodiment, the first PSI or the second PSI are based upon a user input for a target air pressure.
In an embodiment, a welding device can include a gauge that displays at least one of the amount of the portion of compressed air, a target air pressure for the portion of compressed air stored in the reservoir, or an air pressure delivered upon release of the portion of compressed air from the reservoir. In an embodiment, a welding device can include a compartment that stores the air compressor system. In an embodiment, the hose, the nozzle, and the reservoir are detachable from the welding device with the portion of compressed air stored in the reservoir.

In an embodiment, the means for driving the one or more pistons is one of the motor or the energy storage device. For instance, the means for driving the one or more pistons can be a motor of an engine driven welder, an energy storage device associated with an engine driven welder, an energy storage device associated with solely the air compressor system, a motor solely associated with the air compressor system, a combination thereof, a connecting rod for each piston with a crankshaft disposed in a crankcase, and the like. In an embodiment, the means of driving the one or more pistons provides a suction of the portion of ambient air and a compression of the portion of ambient air to become the portion of compressed air. In an embodiment, at least one of the reservoir, the hose, or the nozzle are detachable and removable from the internal compartment.
