ABSTRACT:
A gas shielded arc welding torch is described which uses a consumable electrode wire. A cylindrical support member carries a guide tube for guiding the electrode wire through the torch. An electrical contact member is pivotably mounted at the end of the torch and includes a bore through which the wire passes. A spring biases the contact member into constant engagement with the electrode wire. A gas nozzle is mounted on the cylindrical support member and is movable with the contact member to provide a uniform, constant-dimensioned shielding gas passage around the contact member regardless of the movement thereof.
