Patent

CA 2330069

A process and apparatus for stopping a cutting operation of a plasma arc torch is disclosed which minimizes the oxidation of the electrode to thereby extend life of the electrode. A flow of oxidizing gas is directed through a plasma chamber and nozzle. An electrical current is then conducted through the electrode to form a plasma arc. The electrical current is cut no later than a time F for extinguishing the plasma arc. The flow of oxidizing gas is switched off a determinable time interval before time F, and a flow of non-oxidizing gas is switched on no later than time F, whereby the non-oxidizing gas substantially completely purges the oxidizing gas from the torch creating an inert environment, whereby the plasma arc extinguishes in the inert environment.
