Abstract:
A MIG welding torch reconditioning apparatus comprising torch reconditioning means adapted to hold a reaming tool to be aligned and inserted within a gas shield of the torch and to be operable therein to remove at least some of any back-splash deposits laid down on interior surfaces of said gas shield, said torch reconditioning means comprising a mechanical, impact-clutch intermittent drive coupling arranged intermediate between a motor and said reaming tool, and operable there between to uncouple a reaming tool transmission side of said coupling from a motor-powered drive side of said coupling when, in operation, the torque available from the motor is insufficient to properly rotate the reaming tool against loads occasioned by contact of the reaming tool against welding deposits within the gas shield, whereupon the motor rotates the drive side of the coupling under unloaded-motor conditions until the drive coupling re-couples through complementary mating surfaces thereof to thereby transmit the resulting impact force through the reaming tool and against the contacted deposits.
