It consists of a continuous DC power source for the pilot arc and a bridge connection circuit of multiple semiconductor switches. During welding, the main DC power source of large current is converted into alternating current for welding and is supplied to the electrodes and base metal. An AC plasma arc welding machine comprising: a switching circuit that generates an AC plasma arc based on a trigger; and a drive circuit that switches and drives each of the semiconductor switches.
