Abstract: Engine driven power supplies with output reduction are disclosed. An example engine-driven welding power supply for providing a welding-type output includes an engine, a generator mechanically linked to the engine, power conditioning circuitry, and a controller. The generator generates output power based on mechanical input from the engine. The power conditioning circuitry converts the output power from the generator to welding-type power based on a commanded output. The controller reduce an output of the power conditioning circuitry from the commanded output by an amount proportional to a difference between a speed of the engine and a commanded engine speed while monitoring the difference, decreases the output in response to determining that the reduction in the output does not result in an acceleration in the engine speed, and increases the welding-type output as the difference between the speed of the engine and the commanded engine speed decreases.

Abstract: An engine driven welder comprises an engine coupled to a generator, wherein the engine drives the generator. The engine driven welder employs a first power module coupled to the generator that provides a first weld output and a second power module coupled to the generator, which provides a second weld output. A controller employing a single processor is operatively coupled to each of the first power module and the second power module.
