Engine-driven welding-type power supplies configured to simultaneously use external and engine power

Abstract:

An engine-driven welding power supply, comprising a frame, an engine attached to the frame, and a generator attached to the frame. The generator is driven by the engine and configured to output electrical power via an electrical receptacle. Weld power conversion circuitry is integrally attached to the frame and configured to output welding-type power. A power conductor configured to provide input power to the weld conversion circuitry is configured to be manually coupled to the electrical receptacle or to an external source of electrical power. The weld power conversion circuitry is configured to convert the input power received via the power conductor to welding-type power.
