Abstract
A system and method for re-igniting and stabilizing an arc is provided. The system includes an output system that provides an output waveform, which includes a positive period and a negative period. The positive period includes a positive decay period prior to a transition to the negative period, and the negative period includes a negative decay period prior to a transition to said positive period. The system further includes an inductive discharge and stabilizing system, which includes at least one inductor. The at least one inductor re-ignites an arc between an electrode and a workpiece during the transition period from the positive period to the negative period and the transition period from the negative period to the positive period. The at least one inductor also provides a stabilizing current to stabilize said arc during at least a portion of said positive period and at least a portion of said negative period.
