Patent ID: 6940041

Claim:
An apparatus including welding torch, having a service cable, wherein: the torch includes a torch-handle, and includes an over-handle mounted on the torch-handle; the over-handle, so mounted, is guided on the torch-handle for rotation about a rotation-axis of the torch-handle; wherein the over-handle and the torch handle are positioned to create a space for receiving a web area of a person's hand; the over-handle is functionally operable, and its manner of operation is such that the efficacy thereof is substantially affected by the orientation of the over-handle relative to the torch-handle; a stator-ring is fixedly secured to the torch handle; a rotor-ring is fixedly secured to the over-handle; wherein the stator-ring and the rotor-ring are so structured, mutually, that the rotor-ring is guided for, and constrained against, all modes of movement relative to the stator-ring, other than rotation about the rotation-axis of the torch-handle; the over-handle includes a detent mechanism, which defines N detent-orientations of the rotor-ring upon the stator-ring; in respect of each one of the N detent-orientations; when the rotor-ring lies at the detent-orientation, the detent mechanism provides a heavy resistance to rotational movement of the rotor-ring away from the detent-orientation; when the rotor-ring lies close to the detent-orientation, the detent mechanism provides a large resistance to rotational movement of the rotor-ring in the direction away from the detent-orientation, and provides a small, or negative, resistance to rotational movement of the rotor-ring in the direction towards the detent-orientation.
