A method and apparatus for providing welding power incudes a power supply that receives utility and engine power. The power supply has an engine power input and a utility power input. One of the engine power input and the utility power input is selectively connected to the power supply in response to a mode select input, controlled by an input selector. The input selector may include a user selectable input, such as a sensor circuit or a user switch on a welder control panel, preferably a three position switch having an engine mode position, a utility mode position and an off position in various alternatives. The engine is disabled when utility power is selected. Disabling the engine includes one or more of cutting the field current, starter current, and/or battery current. The power supply may include an inverter, chopper, and/or a phase controlled device. The welder is preferably a single- package, stand-alone, welder, and/or includes an engine/generator having a welding and an auxiliary output.
