ABSTRACT:
An improved electrode holder is disclosed that ensures a fluid cooled electrode will have an outer shank properly positioned relative to a cooling fluid tube. The electrode holder includes a ring portion with an inner periphery having an O-ring and a plurality of jaw teeth which receive the electrode. The electrode has a conically tapered portion at one end which extends from a first diameter outwardly to a second diameter. The inner periphery of the ring portion is of a third diameter intermediate the first and second diameter of the conically tapered portion. The conically tapered portion of the electrode is received within the inner periphery of the ring portion to a certain extent. At a predetermined point the O-ring within the ring portion abuts the conically tapered portion defining a desired position for the electrode. The cooling fluid tube is positioned within a body at a fixed point and is received within the electrode. Thus, it is ensured that the electrode is properly positioned with respect to the cooling fluid tube. The jaw teeth have a cylindrical outer periphery for the majority of their axial extent so that the electrode holder may be easily mounted within most existing electrode combinations.
