ABSTRACT:
A pulse arc welding machine in which current pulses are periodically applied between a welding wire and a base method. A voltage is measured between the welding wire and the base metal to determine if whether an arc to a short-circuit exists therebetween. If a short-circuit exists, a new current pulse is delayed until the arc is reestablished.
