Abstract
A plasma torch is provided having a tubular member defining a bore extending axially between first and second ends, and nozzle engaged with the first end. A movable member is engaged in the tubular member bore, and includes a first end disposed toward the nozzle and a second end, with a piston member engaged therewith away from the first end. An electrode has a first portion defining a bore and is received by the movable member first end. The electrode has a second portion extending outwardly from the movable member first end toward the nozzle, and a radially outward-extending medial flange between the first and second portions axially outward of the movable member first end. The electrode is movable between an inoperable position in contact with the nozzle and an operable position separated from the nozzle and the medial flange in contact with the tubular member first end.
