ABSTRACT:
An improved apparatus for placing current on a moving wire electrode traveling between two points and over a conductive member in the form of a rod. The rod is at an acute angle with respect to the normal straight line of wire travel and its circular outer surface is in contact with the moving wire. The improved apparatus provides a mechanism whereby the conductive member is turned about its longitudinal axis thereby exposing a plurality of different contact surfaces to the wire. An index mechanism is provided for stopping the conductive member at a plurality of positions. An indicator mechanism is also provided for indicating to an operator which contact surface is currently being used. The conductive member is loaded onto the support body from the working end.
