A TIG welding torch (10) including a torch body (22), a metallic front section of the torch body (22) for holding a tungsten rod and conducting electricity to the tungsten rod, and a ceramic nozzle (48a,b,c) for surrounding the metallic front section, wherein a heat isolation spacer (36a,b,c) is provided between the metallic front section and the ceramic nozzle (48a,b,c), the nozzle (48a,b,c) bearing against the outside of the heat isolation spacer (36a,b,c), the heat isolation spacer (36a,b,c) being attached, at a point of attachment, to the metallic front section at a rear end of the metallic front section and a rear end of the heat isolation spacer (36a,b,c), and the heat isolation spacer (36a,b,c) extending forwards of the point of attachment, spaced from the metallic front section to provide a thermal break between the nozzle (48a,b,c) and the metallic front section, and the ceramic nozzle (48a,b,c) being in contact with the heat isolation spacer (36a,b,c) forward of the point of attachment when the ceramic nozzle (48a,b,c) is fitted.
A TIG welding torch including a torch body, a metallic front section of the torch body for holding a tungsten rod and conducting electricity to the tungsten rod, and a ceramic nozzle for surrounding the metallic front section, wherein a heat isolation spacer is provided between the metallic front section and the ceramic nozzle, the ceramic nozzle being fitted over the heat isolation spacer and bearing against the outside of the heat isolation spacer, the heat isolation spacer being attached, at a point of attachment, to the metallic front section at a rear end of the metallic front section and a rear end of the heat isolation spacer, and the heat isolation spacer extending forwards of the point of attachment, spaced from the metallic front section to provide a thermal break between the ceramic nozzle and the metallic front section, and the ceramic nozzle being in contact with the heat isolation spacer forward of the point of attachment when the ceramic nozzle is fitted.
A TIG welding torch including a torch body, a metallic front section of the torch body for holding a tungsten rod and conducting electricity to the tungsten rod, and a ceramic nozzle for surrounding the metallic front section, wherein a heat isolation spacer is provided between the metallic front section and the ceramic nozzle, the heat isolation spacer being attached, at a point of attachment, to the metallic front section at a rear end of the metallic front section and a rear end of the heat isolation spacer, and the heat isolation spacer extending forwards of the point of attachment, spaced from the metallic front section to provide a thermal break between the ceramic nozzle and the metallic front section, the heat isolation spacer being tapered inwardly towards the front of the torch and the heat isolation spacer having longitudinal slots extending from the front of the heat isolation spacer and being provided part way along the heat isolation spacer, the slots defining leaf springs between the slots, and the ceramic nozzle being in contact with the heat isolation spacer forward of the point of attachment when the ceramic nozzle is fitted, the ceramic nozzle being fitted over the heat isolation spacer wherein an inner surface of the ceramic nozzle bears against an outer surface of the heat isolation spacer, and the leaf springs acting outwardly against the inner surface of the ceramic nozzle to grip the ceramic nozzle and retain the ceramic nozzle on the heat isolation spacer.
