Abstract
An engine driven welder-generator including a chopper circuit and being adapted to produce an AC weld output, a DC weld output, and an auxiliary output is provided. The engine driven welder-generator is capable of selectively running at a low engine speed or a high engine speed based on operator inputs and may produce both AC and DC power outputs while utilizing the chopper circuit. The engine driven welder-generator is also adapted to provide an auxiliary output during an AC welding process and a DC welding process.
