1. A welding system, said system comprising:
a torch; a first wire feeder that feeds a first wire to said torch; a first power supply that outputs a welding current waveform to said first wire via said torch, said welding current waveform including a first current segment that is output when said first wire is in contact with a workpiece to melt and transfer a portion of said first wire, and a second current segment that is output during an arcing period between said first wire and said workpiece, said arc creating a molten puddle on said workpiece; a second wire feeder that feeds a second wire to said molten puddle via a contact tube; a second power supply that outputs a heating current waveform that includes at least one of first heating current pulses, which influence said transfer of said portion of said first wire based on magnetic fields created by said welding current waveform and said heating current waveform, and second heating current pulses, which influence a position of said arc relative to said molten puddle based on magnetic fields created by said welding current waveform and said heating current waveform said second power supply providing said heating current waveform to said second wire via said contact tube; and a controller that performs at least one of a first synchronization that synchronizes said first heating current pulses with said first current segment and a second synchronization that synchronizes said second heating current pulses with said second current segment. |
