Definitions
- a useful degree of shielding and cooling of a vulnerable portion of the electrode is achieved, without in any way obstructing normal advance of the electrode through the clamp, and without obstructing vertical movement of the electrode. It is unnecessary to insulate the sleeve electrically from the electrode clamp, and unnecessary and undesirable to provide guides for the electrode within the sleeve.
