220V Spot Welding Machine for Li-ion, Ni-Cd 18650, 21700, 26650 Battery Packs
Professional spot welding machine, ideal for welding nickel strips (0.1mm – 0.25mm) on cylindrical Li-Ion, Ni-MH, and Ni-Cd batteries (18650, 21700, 26650, etc.). Operates with a built-in battery, perfect for mobile repairs, and the maximum output current can reach up to 800A, allowing hundreds of welds on a full charge.
How to Use
- Place the nickel strip between the welding heads and press the foot pedal to trigger the welding.
- Wait approximately 0.5 seconds for the weld to complete, then release the pedal switch.
Recommendations for Welding Quality
- Do not use the machine if the displayed voltage is below 7.3V – charge it in time.
- Do not operate the machine with the charger connected.
- If the welding head oxidizes (turns black), sand it lightly before use.
- The current is adjustable according to the nickel strip thickness:
- Position 5 – for 0.1 mm strip
- Position 6 – for 0.15 mm strip
- Position 8 – for 0.25 mm strip
