LIGHT SYSTEM FOR ENGINE DRIVEN WELDER

TECHNICAL FIELD

The invention described herein pertains generally to a system and method that incorporates an illumination system with an engine driven welder, and in particular, a lighting element that uses power from the engine driven welder to provide illumination of an environment.

BACKGROUND OF THE INVENTION

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.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a welding device that includes a motor-driven welder assembly including a motor that is a power source for the welder device to perform a welding operation and a circuit component that electrically isolates and converts the power source to a first voltage used for controlling the welding operation. The welding device can further include a converter component that converts the first voltage to a second voltage. The welding device can further include a lighting element that uses a portion of the second voltage as a light power source to illuminate the lighting element, wherein the lighting element illuminates based on a switch.

In accordance with the present invention, there is provided a method that includes at least the following steps: utilizing at least one of a motor or an energy storage device to supply a voltage for use with a welding operation; receiving the voltage; reducing the voltage to an isolated second voltage, wherein the isolated second voltage is less than the voltage from the motor; and utilizing the isolated second voltage to power a lighting element.

In accordance with the present invention, there is provided a welding device that includes at least the following: a motor-driven welder assembly including a motor that is a power source for the welder device to perform a welding operation; a circuit component that electrically isolates and converts the power source to a first voltage used for controlling the welding operation; a converter component that converts the first voltage to a second voltage; a housing for containing the lighting element; an energy storage device affixed to the housing, wherein the energy storage device stores a portion of the second voltage; a support member coupled to the housing, wherein the support member is detachable from a housing of the welding device; and means for emitting light using the portion of the second voltage as a primary power source.

These and other objects of this invention will be evident when viewed in light of the drawings, detailed description and appended claims.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention relate to methods and systems that generally relate to converting a voltage generated by a power source of a welding device to a second voltage, wherein the second voltage is lower than the first voltage and is used to power a lighting element. For instance, a first circuit component can convert a voltage from the power source of the welding device, wherein the voltage is used for control of a welding operation. An illumination system can receive a portion of the voltage or convert a portion of the voltage for use as a light power source to power a lighting element to provide illumination to an environment. For example, a motor of a welding device can generate a voltage and such voltage can be converted for control of a welding operation. Additionally, a converter component can be configured to convert and isolate the voltage to a second voltage that is used as a light power source for the lighting element. In another embodiment, the lighting element can include an energy storage device that stores a portion of the second voltage.

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, FIGS. 1-4 illustrate welding systems or devices that can be utilized with the subject innovation. It is to be appreciated that the following welding systems are described for exemplary purposes only and are not limiting on the welding systems that can utilize the subject innovation or variations thereof.

FIG. 1 illustrates a welding device 100. The welding device 100 includes a housing 112 which encloses the internal components of the welding device. Optionally, the welding type device 100 includes a loading eyehook 114 and/or fork recesses. The loading eyehook 114 and the fork recesses facilitate the portability of the welding device 100. Optionally, the welding-type device 100 could include a handle and/or wheels as a means of device mobility. The housing 112 also includes a plurality of access panels 118, 120. Access panel 118 provides access to a top panel 122 of housing 112 while access panel 120 provides access to a side panel 124 of housing 112. A similar access panel is available on an opposite side. These access panels 118, 120, provide access to the internal components of the welding device 100 including, for example, an energy storage device (not shown) suitable for providing welding-type power. An end panel includes a louvered opening to allow for air flow through the housing 112.

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 FIG. 2, a perspective view of a welding apparatus 205 that can be utilized with the subject innovation. Welding apparatus 205 includes a power source 210 that includes a housing 212 enclosing the internal components of power source 210. As will be described in greater detail below, housing 212 encloses control components 213. Optionally, welding device 210 includes a handle 214 for transporting the welding system from one location to another. To effectuate the welding process, welding device 210 includes a torch 216 as well as a grounding clamp 218. Grounding clamp 218 is configured to ground a workpiece 220 to be welded. As is known, when torch 216 is in relative proximity to workpiece 220, a welding arc or cutting arc, depending upon the particular welding-type device, is produced. Connecting torch 216 and grounding clamp 218 to housing 212 is a pair of cables 222 and 224, respectively.

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.

FIG. 3 illustrates a trailer 300 incorporating a trailer hitch or hitching device, depicted generally at 301.

The trailer 300 may also include an adjustable stand 310 for adjusting the height of the front end 312 of the trailer 300. However, any means may be used for raising and/or lowering the front end 312 of the trailer 300. The trailer hitch 301 may be a generally longitudinal and substantially rigid trailer hitch 301 and may be attached to the frame 302 via fasteners 314, which may be threaded bolts.

FIGS. 4A and 48 illustrate a hybrid welding device (herein referred to as a “hybrid welder”). A hybrid welder according to the invention is generally indicated by the number 400 in the drawings. Hybrid welder 400 includes an engine component that runs on fuel from fuel storage 410 allowing the hybrid welder 400 to be portable. It will be appreciated that hybrid welder 400 may also be mounted in a permanent location depending on the application. Hybrid welder 400 generally includes a motor-driven welder assembly 420 having a motor 425 and an energy storage device 430. Motor 425 may be an internal combustion engine operating on any known fuel including but not limited to gasoline, diesel, ethanol, natural gas, hydrogen, and the like. These examples are not limiting as other motors or fuels may be used.

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 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.

By way of example and not limitation, first circuit component 520 can be an isolation stepdown circuit. Moreover, it is to be appreciated that first circuit component 520 can be chosen with sound engineering judgment without departing from the intended scope of coverage of the embodiments of the subject invention. For example, although welding device 500 is illustrated with first circuit component 520, any suitable number of circuits can be utilized by the subject innovation.

First circuit component 520 can be configured to isolate and convert the voltage from power source 510. First circuit component 520 can further condition voltages from power source 510 so as to reduce effects from power source 510. By way of example and not limitation, conditioning can relate to a filtering of a signal, a noise reduction of a signal, isolation of a signal, and the like.

It is to be appreciated and understood that converter component 530 can be a stand-alone component (as depicted), incorporated into first circuit component 520, or a combination thereof. Illumination system 525 utilizes the second voltage as light power source 540 to provide lighting or illumination to an environment (discussed in more detail below). Converter component 530 can provide a conversion of a portion of the first voltage and at least one of an isolation of the second voltage or a conditioning of the second voltage. By way of example and not limitation, conditioning can relate to a filtering of a signal, a noise reduction of a signal, isolation of a signal, and the like.

Switch component (not shown) can automatically select between motor component and energy storage device for a power source for the welding operation performed by the welding device 600. In an embodiment, the switch component can select between motor component and energy storage device based upon 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 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 fuel available for motor component, 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 600, and the like.

For example, welding device 600 can include first circuit component 520 to convert voltage from power source 510 for use with control of a welding operation on a workpiece. For instance, a hardware link board can be used to convert and isolate voltage from power source 510 to use for the welding operation or control thereof. In such example, the hardware link board can step down voltage from power source 510 to 40 volts. In an example, converter component 530 can convert the 40 volts to a second voltage that is lower than 40 volts and use such second voltage with illumination system 525. In still another embodiment, the hardware link board can incorporate converter component 530 to provide the second voltage.

Illumination system 525 can include switch 610 that activates or deactivates lighting element 550. For instance, switch 610 can control electric flow (e.g., second voltage) between light power source 540 and lighting element 550. It is to be appreciated that the manner of how switch 610 activates or deactivates the second voltage to lighting element 550 can be chosen with sound engineering judgment without departing from the intended scope of coverage of the embodiments of the subject invention.

Further, housing 620 can contain energy storage device 630. Energy storage device 630 can store a portion of the second voltage to allow for a portable use of lighting element 550. For instance, lighting element 550 can be electrically decoupled from welding device 600 and/or light power source 540, wherein a stored portion of the second voltage within energy storage device 630 is used to illuminate lighting element 550. It is to be appreciated that for the sake of brevity any components or circuitry that provides use of stored second voltage in energy storage device 630 are not illustrated but one of sound engineering judgment can chose circuitry and/or components to allow portability and decoupling use of lighting element 550.
