ABSTRACT:
An apparatus and method for fusing terminal or commutator wire connections on an armature or stator, including an electrode, a pneumatic locking cylinder for driving the electrode into contact with the workpiece and applying a force to the workpiece, a load cell for measuring the force applied by the electrode, an opposition cylinder for providing an opposition force to the electrode after a cold-forming force has been reached by the electrode, a linear potentiometer for measuring the distance traveled by the electrode after the opposition force has been applied; and a locking mechanism for stopping the locking cylinder after a predetermined distance has been traveled during the weld cycle.
