Abstract:
1. A welding system comprising: a welding power source configured to apply electrical power to a welding torch for a welding operation; a secondary power source configured to provide a variable voltage output; a capacitive storage device charged by the secondary power source; a transformer having a primary winding coupled to the output of the secondary power source for receiving power from the secondary power source and establishing a resonant frequency signal between the capacitive storage device and primary winding, and a secondary winding coupled to the welding power source; and a switching device for regulating resonant rings between the capacitive storage device and the primary winding; wherein the transformer superimposes the resonant frequency signals onto the welding power signal of the welding power source during periods of the resonant rings, and the energy of the superimposed signals being variable based upon the voltage of the secondary power source output.
