    AMADA MIYACHI'S range of Advanced Dual Pulse (ADP) Capacitive Discharge welders provides a superior level of welding performance, with both advanced process monitoring and a simplified user  interface.  The design includes a proprietary charging unit to improve pulse rise times and repetition rates. The built-in weld monitor with color display provides at-a-glance information of weld and process performance.  Unique features like programmable pulse polarity and uplsope enable fast, easy setup and ensure even nugget formation and electrode wear in series welding, as well as a means to alleviate weld splash.

    These dual pulse spot welders are ideal for :

    • Welding nickel battery tabs
    • Spot welding stainless steel
    • Battery pack welding
    • Battery spot welding
    • Battery tab welding
    • Honeycomb welding
    The stored energy welding power supply  - commonly called a Capacitive Discharge Welder or CD Welder - extracts energy from the power line over a period of time and stores it in welding capacitors. Thus, the effective weld energy is independent of line voltage fluctuations. This stored energy is rapidly discharged through a pulse transformer producing a flow of electrical current through the welding head and workpieces. 

    Capacitive discharge power supplies are rated in accordance with the amount of energy they store and the welding speed. The energy stored, expressed in watt-seconds (joules), is the product of one-half the capacitance of the capacitor bank and the square of the applied voltage. The energy delivered to the electrodes is considerably less than this value because of losses in the primary and secondary circuits.

    Some capacitor discharge power supplies provide a 'Dual Pulse' feature which allows the use of two pulses to make a weld. The first pulse is generally used to displace surface oxides and plating, and the second pulse welds the base materials. This feature also reduces spitting.

    Advantages of CD welder technology include:
    • Repeatable energy independent of line voltage fluctuations
    • Fast energy release, suitable for welding highly conductive metals such as copper
    • Small heat affected zones
    For more information regarding how to choose the right power supply for your application, read our blog: 'AC, DC, CD or HF: Which Spot Welding Power Supply Should I Use?

    ADP Series welders may be used in conjunction with one of our many weld heads as a single operator benchtop unit and is well-suited for integration into semi or fully automated resistance welding systems.  AMADA MIYACHI specializes in designing and building fully integrated, semi-automated and fully automated resistance spot welding machines.  See our Integrated Systems brochure for more information.

    And for more information about the resistance welding process read our Fundamentals of Resistance Welding and Fine Spot Resistance Welding Applications.
