  • Resistance welding with an electrochemical capacitor as the current power source
    Patent number: 6303894
    Abstract: A resistance type pulse welding apparatus for workpieces, including a handpiece, a pair of electrodes mounted at the tip of the handpiece adapted for delivering weld current pulses to a workpiece to be welded, an electrochemical capacitor providing a high-current, low-voltage power source, and a triggering means located between the electrochemical capacitor and the electrodes to discharge the energy stored in the electrochemical capacitor through the electrodes upon the sensing of a threshold pressure between the electrodes, indicative of the forcing of the electrodes against the workpiece.
