Abstract: Embodiments of a welding power supply include an engine adapted to drive a generator to produce a first power and a energy storage device adapted to discharge energy to produce a second power. The welding power supply also includes control circuitry adapted to detect a commanded output. The control circuitry is adapted to meet the commanded output by controlling access to power from the energy storage device to produce the second power when the commanded output is below a first predetermined load level. The control circuitry is further adapted to meet the commanded output by controlling access to power from the engine and the energy storage device to produce the first power and the second power when the commanded output is above a second predetermined load level.

Abstract: A hybrid welding system is provided. In one embodiment, the welding system includes an engine-driven generator, an energy storage device, a contactor, and a controller. The controller may be configured to control delivery of weld power from the generator when a commanded output is below a threshold level, and from both the generator and the energy storage when the commanded output is above the threshold level. Closing of the contactor enables the energy storage device to contribute to weld power during welding operations and to be charged by the generator output independent of charging between weld operations. Additional hybrid welding systems and methods are also disclosed.

Abstract: A welding system includes an engine configured to drive a generator to produce a first power output. The welding system also includes a battery configured to discharge energy to produce a second power output. In addition, the welding system includes an auxiliary charger coupled to the battery and the generator. The auxiliary charger is configured to maintain a float charge of the battery when the first and second power outputs are reduced from a base load.
