    Abstract: A welding system includes a power source configured to generate power and deliver the power to a welding torch. The power is provided in accordance with an electrode negative pulse welding regime that includes a cyclic peak, followed by a stabilization phase, then a return to a background level. The stabilization phase has a generally parabolic current shape, and is performed in a current-closed loop manner until a transition point, where control becomes voltage-closed loop until the background level is reached. Resulting weld performance is improved, with a globular-like transfer mode, reduced shorts and enhanced arc stability.

    Abstract: 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.

    Abstract: Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.
