Beschreibung
Zusammenfassung:	An electric arc welder for performing a pulse welding process by a current between an advancing electrode (E) and workpiece (W) where the welder comprises a short detecting circuit for creating a short signal upon occurrence of a short circuit between the advancing electrode (E) and the workpiece (W) and a boost circuit to create a plasma boost pulse (320,412,600,600a,740,850,930) after the short circuit is cleared during the time period when the welder is not outputting the peak pulse current.
