Spot Welding Machine Accessories DIY Welding Pen Set 12V 18650 Lithium Battery Spot Welding Machine
The user needs to prepare 12V battery for power supply, and the welding current is about 90A ~ 130A. It is easy to weld the common 0.1mm ~ 0.12mm nickel plate. Please make sure that your battery can have a current greater than 90A, otherwise you will not be able to weld!
System voltage: 12V-15V
Working current: 90-150A (discharge below 90A, will not work)
1. The smart spot welding program was added, the trigger switch was abandoned, and automatically control the spot welding action via program. When the soldering pen touches the nickel sheet, the spot welding pulse is automatically output. No need to press the switch. At the same time, the delay spot welding mode is abandoned.
2. Upgrade from the original third gear to the current 5 gear. This can better adapt to different batteries, and batteries with lower performance can also be spot welded. At the same time, it is more applicable.
3. The structure of the board has been optimized, and the circuit design is more reasonable! The MOS tube driving part of the board is widened and tinned, which effectively reduces the resistance and increases the overcurrent capability!
4. Add 4 screw holes, suitable for installation in a small box.
20-45Ah lead-acid battery with good performance and small internal resistance

18650 battery pack with 30-35Ah capacity
Spot welding is welded by the principle of rapid local heating and cooling of large currents. It requires sufficient current supply. Generally, the current of 0.1-0.15 nickel plate welding is about 90-150A, so the working power supply of the circuit board must be greater than or equal to 150A.
