ABSTRACT:
A plasma arc torch which has a cooling water passage for cooling both the electrode and the nozzle, and separate passages for a cutting gas and a shielding gas. The nozzle is centered and longitudinally held by an interengaging fit with a tubular member of the torch body, and the torch includes a heat shield assembly which retains and supports the nozzle of the torch on the tubular member. The heat shield assembly also defines a portion of the cooling water passage as well as a portion of the shielding gas passage, and it may be unthreaded and removed from the torch as a unit. When so removed, the water passage is opened which acts to disconnect the power to the torch.
