PULSE WELDER AND METHOD OF USING SAME

摘要

An electric arc welder for performing a pulse welding process by a current between an advancing electrode and workpiece where the welder comprises a short detecti ng 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.
