Abstract

An arc welding machine comprises an output control circuit which produces an arc output in accordance with output control signal, an output detection circuit which measures the state of arc output and produces a feedback signal indicative of the output arc state, and a fuzzy inference control circuit which introduces the feedback signal, produces a welding current waveform and welding voltage waveform required to produce the optimal arc state based on the fuzzy inference, and delivers the resulting waveforms to the output control circuit as the output control signal.
