发明名称 PROCESS FOR INITITATION OF PLASMA ARCH
摘要 A process for starting a plasma arc torch (10) is disclosed which minimizes the oxidation of the electrode (14) to thereby extend the life of the electrode (14). A flow of non-oxidizing gas is first generated between the discharge end of the torch electrode (14) and the nozzle assembly (12) of the torch (10). A pilot arc then is created between the discharge end of the electrode (14) and the nozzle assembly (12). The pilot arc is transferred and the flow of non-oxidizing gas is terminated. A flow of oxidizing gas then is generated for plasma formation.
