ABSTRACT:
An over-handle is mounted on a rotor-ring for rotation around the handle of the torch. The accessory is for use with a torch of the kind in which a (coated) electrode is mounted in an electrode holder, and is tightened therein by the welder screwing the holder into the torch handle. The orientation of the electrode relative to the handle is unpredictable, and the rotatable over-handle enables the over-handle to be orientated to suit the orientation of the electrode. A rotatable accessory in the form of a pick hammer is also disclosed.
