A method and apparatus that provides welding-type power is disclosed. It includes a power source, a welding output, an inductor winding and an auxiliary winding. The inductor winding is in electrical communication with the power source and the welding output. The auxiliary winding is preferably in magnetic communication with the inductor winding, and in electrical communication with the power source and the welding output. A switch is in electrical communication with the auxiliary winding, a controller with a control output is connected to the switch, the auxiliary winding is anti-parallel with the inductor winding in the preferred embodiment. The auxiliary winding may be used to create a variable output inductance.
