Реферат: Abstract of The Disclosure A plasma arc cutting torch is disclosed which includes a nozzle assembly below the electrode for injection of water around the plasma flow so as to constrict the arc. The nozzle assembly includes upper and lower disc like nozzle members which are spaced apart to define a water gap therebetween, and the members include aligned bores for permitting the plasma to flow therethrough to the underlying workpiece. The lower nozzle member is of extended length, and its forward or lower end portion is beveled to define a frusto-conical exterior surface, so as to permit the torch to be positioned closely adjacent the workpiece when making beveled cuts and so as to achieve the predetermined standoff which maximizes the quality and speed of the cut.
