1. A welding machine, comprising:
a welding power supply that generates a welding waveform during a welding operation;
an internal combustion engine;
a generator operatively connected to the welding power supply to supply electrical energy to the welding power supply, wherein the generator comprises 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 mounted to the end casting of the generator; and
a clutch mechanism that couples the rotor shaft to the rotary screw compressor to selectively drive the rotary screw compressor by the rotor shaft,
wherein the end casting includes a rotor shaft bearing that supports the rotor shaft.
