Description
The 12V Spot Welding Machine is a compact, portable welding module designed for battery tab welding, especially for lithium-ion cells such as 18650, 26650, and 32650. Ideal for DIY battery pack builders, this module offers efficient pulse welding with adjustable power levels. Powered by a 12V battery or power supply, it is lightweight and easy to integrate into any small workshop setup.
Specifications
- Input Voltage: 12V DC (Lead-acid battery or high-current power supply)
- Welding Current: Up to 200A (depending on power source)
- Control: Capacitive energy storage with timing control circuit
- Pulse Mode: Dual pulse for strong welds and reduced burn-through
- Welding Thickness: Up to 0.15mm nickel strip
- Display: LED indicators (varies by model)
- Cooling: Passive cooling or optional fan
- PCB Size: Approx. 10cm x 4cm (varies by version)
Applications
- DIY lithium-ion battery pack welding
- 18650 and 26650 cell connections
- Battery repair and maintenance
- Portable electronics and e-bike battery building
Usage Notes
- Requires a 12V high-discharge battery or power supply (minimum 150A burst capability recommended).
- Use high-quality nickel strips for optimal conductivity and clean welds.
- Do not touch welding probes during operation—risk of burn or electric shock.
- Adjust pulse timing based on material thickness and power source.
- Improperly installing the 2200μF capacitor or using a voltage higher than 14.6V may greatly increase the risk of burning the power tube.
- Use 30–45AH lead-acid batteries in good condition. Recycled or degraded batteries may fail to meet the current requirements.
- If using a battery larger than 45AH, extend the input cables by at least 80cm to prevent current overload and module failure.
