Abstract
Systems and methods for a welding-type power supply to provide both a welding output voltage and a battery charging output voltage. The power supply includes a first contactor associated with a first circuit to provide the welding output voltage, and a second contactor associated with a second circuit to provide the battery charging output voltage. An auxiliary switch is operatively coupled to the second contactor, to prevent the first circuit from closing when the second contactor is closed to prevent transmission of the welding output voltage to the second circuit.
