    AC Pulse Spot Welder | Resistance Welding Machine Supplier ...
    An AC Pulse Spot Welder uses standard AC power, stepping it down to low voltage but high current, delivering it in precise, controlled pulses (milliseconds) to fuse metal parts, ideal for battery tabs (nickel to nickel/steel) or small metal components, offering better heat control and less distortion than DC welders, often featuring digital controls, presets, and safety features like isolated triggers, making them perfect for building battery packs or working with delicate electronics and jewelry. 
    This video provides a comprehensive overview of how an AC pulse spot welder works:

    YouTube • Nov 27, 2020
    How it Works 
    1. Power Input: Takes standard AC power (e.g., 110V/220V).
    2. Transformer: Steps down voltage and boosts current.
    3. Pulse Control: A control circuit (often using timers like a 555 timer) generates very short, timed electrical pulses.
    4. High Current Delivery: These pulses send a brief, high-current surge to the electrodes.
    5. Resistance Heating: The metal's electrical resistance at the contact point creates intense heat, melting a small spot to fuse the pieces.
    6. Pulse Duration: The pulse time (e.g., 0.2-20ms) and power (0-99 settings) are precisely adjustable for different materials and thicknesses. 
    You can see a demonstration of the AC pulse spot welder in action in this video:

    Key Features & Benefits 
    • Precise Control: Digital displays and adjustable power/time settings (0-99) for accurate, repeatable welds.
    • Material Versatility: Welds stainless steel, nickel, brass, iron, and is excellent for battery tabs (18650, 21700, etc.).
    • Enhanced Safety: Isolates high-current primary circuits from the user-operated trigger, preventing electrocution.
    • Dual Pulse: Some models use a first pulse to clean surfaces and seat electrodes, with a stronger second pulse for the weld, ensuring better quality.
    • Applications: Battery pack assembly, electronic component repair, jewelry making, hardware manufacturing. 
    This video explains the concept of dual-pulse welding for battery assembly:

    Types 
    • Handheld/Manual: Uses a pen with electrodes and a foot pedal or button.
    • Pneumatic: Uses compressed air for consistent electrode pressure, common in industrial settings.
    • Desktop/Tabletop: Often pedal-operated for hands-free use with small parts.
