Abstract
A small bore welding torch for tungsten inert gas welding includes a copper rod which functions as an electrical conductor to the tungsten electrode which is anchored in a cross bore adjacent one end of the rod and as a tie to hold two insulative sleeves in assembly. An annular passage surrounds the copper rod and between the rod and outer sleeve provides an inert gas conduit to the welding electrode which projects into a side port in a refractory sleeve.
