This plasma arc torch includes an improved front end assembly to create an improved gouge path when compared with prior art plasma arc gougers. The front end assembly includes a unique secondary gas nozzle for distribution of the secondary gas in a partial radial blanket up to 300 DEG around the plasma. Conventional nozzles distribute the seondary gas in a total, 360 degree, blanket around the plasma. An improved tip design is believed to develop an enlarged plasma stream to further enhance the gouging process.
