ABSTRACT:
A long wearing contact tip for an inert gas arc welder comprises an elongated cylindrical copper member having a longitudinal bore therethrough. A portion of the bore is enlarged for receiving a steel liner formed of either spiral wound steel wire or steel tubing. Circumferential grooves are cut into the external surface of the contact tip to afford better cooling of the tip by the inert gas flowing past the tip.
