ABSTRACT:
A method and apparatus for initiating an electrical discharge in a formation of flowing inert gas disposed adjacent the end of an electrode by generating charged particles in the vicinity of said inert gas formation. The charged particles may be generated by various means such as an electron emissive filament, a radioactive material or an auxiliary electrical discharge located adjacent to the electrode but removed from the end thereof. The auxiliary electrical discharge may be in electrical series with the electrode and it may be located inside or outside the flow of inert gas needed to establish the gas formation at the end of the electrode.
