摘要： An electric arc welder ( 100 ) and a method of performing a pulse welding process producing reduced spatter. The welder produces a current between an advancing electrode (E) and a workpiece (W). The welder includes a short - detecting capability for detecting a short condition upon occurrence of a short circuit between the advancing electrode and the workpiece. The welder may also include a switching module in the welding circuit path of the welder having an electrical switch and a resistive path. Times of occurrence of short intervals can be tracked and a blanking signal can be generated based on the tracked short intervals to anticipate a next short interval in a next pulse period of the pulsed welding process. The blanking signal can be used to reduce a welding current in the welding circuit path by introducing additional resistance into the welding circuit path via the switching module ( 110 ), or by controlling a portion of a waveform of the welding process during the blanking interval.
