ABSTRACT:
A hot wire welding torch assembly includes a nonconsumable metal electrode 12, a filler metal 6 fed to a weld puddle 11 fomed by an arc 10, a collet body 15 for holding the electrode, a shielding gas nozzle 3, and a torch body 1 molded from a synthetic resin for coaxially mounting the collet body and shielding gas nozzle. A highly dielectric and heat-proof insulating bushing 14 is provided between the torch body and a clamping holder 2 for mounting the torch body 1 to a filler metal torch 4 to prevent any relative slippage between the two torches and avoid electrical shock hazards.
