The plasma torch has a hot cathode (3) connectable to the negative poles of a main current course and of an arcing current source, an anode (2) connectable to the positive pole of the main current source, and an inter mediate arcing electrode (6) connectable to the positive poles of both sources. An inert gas is introduced (at 8) between the cathode (3) and the arcing electrode (6). A plasma-producing gas is introduced (at 4) between the arcing electrode (6) and the anode (2). A fuel supply… CONTINUE READING
