  • Fusing apparatus and method using concave shaped electrodes
    Patent number: 5153404
    Abstract: An electrode set for a fusing apparatus includes a first electrode and a second electrode each having concave shaped end faces formed from cylindrical openings. The electrode set provides enhanced fusing of magnet wire circumferentially about a terminal pin of, for example, a coiled bobbin. The heat generated during the fusing process melts the insulation on the magnet wire to permit the fusing of the wire circumferentially to the pin.
