Abstract
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.
