ABSTRACT:
The nozzle of an inert gas arc-welding gun is flexibly extended by coupling an elongate, tubular electrode between the body of the gun and its nozzle. The electrode is formed of spirally-wound conductive wire capable of being bent into any desired configuration needed for the particular job and of retaining its set disposition. A sleeve binds the wound wire electrode to maintain its circularity during bending and insulation is provided around the sleeve. Welding current is carried by the wire and the welding metal in wire form is passed through the bore of the wound wire. A steel spring coaxial with the electrode guides the welding wire. Inert gas is supplied through a passage provided between the insulation and the sleeve.
