Abstract
A method and apparatus for providing engine driven welding-type power supply includes an engine, a generator, an input power circuit, a welding-type power circuit, an auxiliary power circuit and a controller. The generator includes permanent magnets that create and provides a generator output from at least one polyphase winding. The input power circuit is connected to the generator output and the welding-type power circuit is connected to the input circuit, and provides a welding-type output. The auxiliary power circuit is connected to the input circuit and provides an auxiliary power output. The controller is connected to the auxiliary power and the welding type power circuits, and can command that there be no load for the generator. The generator is connected to the engine and connected to function as a flywheel to the engine and the engine does not include a flywheel other than the generator.
