An example engine driven welder/generator system is disclosed that includes a turbo charged gasoline powered engine connected to an electric welder/generator. The welder/generator is configured to provide an output to an auxiliary welding system. The turbo charger system enhances operation of the gasoline engine by powering a turbine with engine exhaust to drive a compressor to increase intake of air, resulting in compressed air providing more powerful explosions in an engine combustion chamber once fuel is added and ignited. The resulting engine drives the welder/generator to provide a more consistent torque curve, while generating less noise per unit of power output in comparison to a diesel engine.

Various welding systems including a welding torch assembly are provided. The welding torch assemblies may include a welding torch adapted to be utilized in a welding operation to establish a welding arc between the welding torch and a workpiece. The welding torch assemblies may also include a temperature sensing system integral with the welding torch and adapted to sense a temperature of the workpiece.

A welding or additive manufacturing system includes a power supply having a controller which controls operation of the power supply. The power supply provides a current waveform to a contact tip assembly having a first bore terminating at a first exit orifice and a second bore terminating at a second exit orifice. The first exit orifice is configured to deliver a first wire electrode and said second exit orifice is configured to deliver a second wire electrode. The exit orifices are separated from each other by a distance configured to facilitate formation of a bridge droplet between the wire electrodes while preventing solid portions of the first wire electrode delivered through the first bore from contacting solid portions of the second wire electrode delivered through the second bore, during a deposition operation in which the current waveform is conducted to both of the wire electrodes simultaneously through the contact tip assembly.

A welding system is provided that includes an engine, a compressor coupled to the engine, and a regulator coupled to the compressor and located on a control panel. Another welding system is provided that includes an engine, a compressor coupled to the engine and a monitor circuit configured to monitor the duration of operation of the compressor by monitoring engagement of the clutch. A pressure gauge configured to be coupled to a compressor is also provided.

Methods and apparatus to synergically control a welding-type output during a welding-type operation are disclosed. An example welding-type power supply includes a power conversion circuit configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch; a communication circuit configured to receive a control signal from a remote control device during a welding-type operation; and a control circuit configured to synergically control a voltage of the welding-type power and a wire feed speed based on the control signal.

A welding-type power supply that receives alternating current (AC) input power and converts the AC input power to direct current (DC) power to provide power for welding tools. The welding-type power supply is configured to detect whether single phase AC power or three-phase AC power is connected to the input of welding-type power supply. Single phase input power may be detected by sampling ripple voltage of the DC power, either synchronously with the AC input power or synchronously with a signal generated by an output of the welding-type power supply.

A portable advanced process module system includes, for example, a welding power source, an portable advanced process module, and a wire feeder. The portable advanced process module and the wire feeder are separately enclosed in suitcase style enclosures with disconnectable power and communication means between the portable advanced process module and the wire feeder. The processing unit includes power electronics to enable advanced weld processes that can be delivered to the wire feeder and a welding work piece. The portable advanced process module is powered by a DC bus that can be supplied by a welding power source. Connecting the portable advanced process module between the welding power source and the wire feeder enables advanced welding processes to be accomplished at great distances from the main welding power source. Separating the power electronics into the portable advanced process module and maintaining a standard suitcase wire feeder form factor keeps the welding equipment used in the working area envelope small, light, and portable.

An example fluid container configured to receive a fluid, with a filler neck configured to channel the fluid from an inlet into the fluid container. In some examples, a flexible hose connects the fluid container to the filler neck.

A system, in one embodiment, may include a portable unit having an engine, a generator coupled to the engine, a compressor coupled to the engine, and a priority load controller. The controller may be configured to adjust various loads on the engine, the generator, or the compressor, or a combination thereof, in response to a priority control scheme. A computer-implemented method, in another embodiment, may include adjusting power output to various loads on an engine, a welding generator coupled to the engine, or an air compressor coupled to the engine, or a combination thereof, in a portable welding unit in response to a priority control scheme.
