Abstract

The invention provides a plasma cutting torch 1 with high- frequency ignition which comprises a coaxial anode 5 around the outside of a cathode 2, both being fixed to an insulated body 3 inside which is a central shaft 8 for adduction of the electric power supply, while on the outside is an insulated nozzle 12. A stream of ionizable gas 30 flows through channels 15,17,19 formed inside the torch and, before passing out through the orifice 6 of the anode 5 to generate the jet of plasma 39, cools the internal part of this anode 5. <IMAGE>
