Abstract
A system and method is provided in which at least two welding power supplies are coupled to respective weld torches where the power supplies each provide a pulse welding waveform to their respective weld torches such that the welding pulses are out of phase with each other such that the respective welding pulses do not overlap during welding. The system also includes a ground current switch which switches the ground current path during welding to minimize arc interference and arc blow.
