发明名称 WELDING SYSTEM AND METHOD FOR ANOMALOUS CATHODE EVENT CONTROL WITH CONTROL OF WELDING CURRENT ACCORDING TO THE STATE DETECTED VOLTAGE
摘要 A method of operating a welding system includes supplying a weld current and a weld voltage to an electrode via a plurality of pulse periods, where each pulse period of the plurality of pulse periods includes a background phase and a peak phase. The method also includes detecting the occurrence of an anomalous cathode event during the background phase of a first pulse period of the plurality of pulse periods based at least in part on when a voltage value of the weld voltage is greater than a detect voltage. The method also includes controlling the weld current to a desired current during a portion of the anomalous cathode event. The portion includes an interval of the background phase of the first pulse period, and the weld current is controlled independent of the weld voltage during the portion of the anomalous cathode event.
