A plasma arc torch is disclosed which has the ability to be configured for operation in either the transfer arc mode or the non-transfer arc mode. The torch includes a rear housing section which mounts a rear electrode, a gas vortex generator, and releasable mounting means. The releasable mounting means is adapted to mount either an electrode assembly for operation of the torch in the non-transfer arc mode, or a collimating nozzle assembly for operation in the transfer arc mode. The torch also includes a coolant passageway which is constructed and arranged so as to mate with cooperating passageways in either the electrode assembly or the collimating nozzle assembly, for removing heat from the internal components of the torch. |
