Abstract
A welding machine includes a welding power supply that generates a welding waveform during a welding operation, an internal combustion engine, and a generator that is operatively connected to the welding power supply to supply electrical energy to the welding power supply. The generator includes a rotor shaft driven by the internal combustion engine, and an end casting located at an end of the generator opposite the internal combustion engine. A rotary screw compressor is mounted to the end casting of the generator. A clutch mechanism couples the rotor shaft to the rotary screw compressor to selectively drive the rotary screw compressor by the rotor shaft.
