Abstract:
1. A system for re-igniting and stabilizing an arc in arc welding applications, said system comprising: an output system that provides an output waveform to one of an electrode and a workpiece, said output waveform comprising a positive period and a negative period; an inductive discharge and stabilization system operatively connected to said output system and comprising at least one inductor; and a control unit operatively connected to said inductive discharge and stabilizing system and said output system, wherein said positive period comprises a positive decay period prior to a transition to said negative period, and said negative period comprises a negative decay period prior to a transition to said positive period, wherein said at least one inductor re-ignites an arc between said electrode and said workpiece during said transition period between from said positive period to said negative period and said transition period from said negative period to said positive period, wherein said at least one inductor 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, wherein said control unit controls said inductive discharge and stabilization system such that said at least one inductor is charged during said positive decay period and said negative decay period.
