A quick change device has a mounting member for mounting an actuator to a resistance welding gun by headed fasteners. The mounting member has several keyhole type apertures arranged in a circle. The fasteners extend through the narrow portions of the keyhole type apertures and the fastener heads clamp the mounting member to the welding gun. To detach the actuator, the mounting member is first released by loosening the fasteners and rotating the mounting member until the heads of the fasteners align with the wide portions of the keyhole type apertures. An additional fastener extends through a round aperture which is removed before the mounting member is released and the actuator is detached.

A weld nut electrode for differentiating between a properly and an improperly oriented weld nut. The electrode has a conductive portion for passing weld current through the weld nut and an insulated portion electrically isolated from the conductive portion. The conductive portion makes electrical contact with a properly oriented weld nut, and the insulated portion is arranged to prevent physical contact between the conductive portion and an improperly oriented weld nut.
