ABSTRACT:
A welding material supply mechanism for providing a welding bead on a surface comprising: a first hollow arm, a transfer tube, a second hollow arm, swivel bearing and a welding nozzle. The first hollow arm is connected to the second hollow arm by a swivel bearing, and a remote end of the second hollow arm supports a nozzle for facilitating welding on a surface. The swivel bearing facilitates pivoting movement of the second hollow arm relative to the first hollow arm to adjust a diameter of the welding bead to be formed on the surface, and a locking coupler facilitates locking the pivoted and adjusted position of the first hollow arm relative to the second hollow arm. The transfer tube is at least partially received within the first hollow arm and is concentric therewith. The transfer tube supports a female electrical connector coupled to the swivel bearing, the transfer tube establishes a welding electrical current path to the nozzle via the swivel bearing and the second hollow arm. A wire conductor is located within the transfer tube for supplying a welding wire to the nozzle, via the swivel bearing and the second hollow arm. A welding gas flow path is defined between an exterior surface of the wire conductor and an inwardly facing surface of the transfer tube to supply a welding gas to the nozzle via the swivel bearing and the second arm.
