In a wire discharge machine, threading of the wire is accomplished by tensioning the wire to straighten same and applying an electric current thereto to facilitate separation thereof. Clamps hold and help tension the wire by securing one or more ends at a particular location. The tensioning is accomplished with drive motors, which may be or include pulse motors.
