LIQUID-COOLED PLASMA TORCH WITH TRANSMITTED ARC

摘要

20337-375 The invention relates to a liquid-cooled plasma torch with transferred arc, its coolant, current and gas being guided to the ignition and main electrode via ignition electrode and main electrode lances consisting of coaxial tubes. To structurally improve the torch, to minimize the heat losses of the torch jacket and to increase the efficiency of the torch, a common coolant circuit is provided for the ignition electrode lance and the main electrode lance.
