Abstract

High frequency discharge priming device, for welding or electric arc cutting in rare gas atmosphere, with infusible electrode, which includes a welding or cutting current generator, a torch with a nozzle surrounding said electrode and a generator of high frequency current for priming, characterized in that said generator is connected by coaxial cables to two electrodes fixed to the torch nozzle and because it is not connected to the welding or cutting electrode.
