Abstract: A torch for performing TIG welding is disclosed. In accordance with at least one embodiment of the present invention, the torch includes a torch body having a cavity configured to receive and support an electrode assembly, a first shield gas channel, and a second shield gas channel. The first shield gas channel extends from an external surface of the torch body to a first plenum that is fluidly coupled to the cavity so that the first shield gas channel is configured to direct a first shield gas into the cavity. The first plenum is defined, at least in part, by the cavity and is disposed radially exterior of a portion of the electrode assembly. The second shield gas channel is configured to direct a second shield gas to exit the torch body along a path that that is radially exterior of the cavity.

Abstract: A torch for performing TIG welding is disclosed. The torch includes an electrode for a TIG/GTAW welding operation with an inert gas and an active gas. In accordance with at least one embodiment of the present invention, the torch includes a torch body having a first fluid channel and a second fluid channel, an electrode assembly disposed in the torch body, a nozzle concentric with the electrode and a shield cap concentric with the nozzle. An angle between a longitudinal axis of the electrode assembly and an outer surface of at least one of the electrode holder and the electrode is about nine degrees.
