Striking a main arc between plasma and metal workpiece - using an auxiliary alternating current circuit

An auxiliary arc is struck between the electrode and the jet in the burner, using a high-frequency discharge, and plasma gas is fed to the burner so the flare bridges the gap between the electrode and the workpiece, thereby striking the main arc. The amplitude of the auxiliary high-frequency current...
