Abstract
An electric arc welding device for performing a pulse welding process by a current between an advancing electrode and workpiece where the welder comprises a short detecting circuit for creating a short signal upon occurrence of a short circuit between the advancing electrode and the workpiece and a boost circuit to create a plasma boost pulse after the short circuit is cleared during the time period when the welder is not outputting the peak pulse current. The peak pulse current to background current ratio is high and the duration of the peak pulse is short.
