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.
