12v Diy Portable Spot Welder Machine Battery Storage Pcb Circuit Board Welding Device Tool Set

Description

Welding current is about 90-150A. Through the output of the MOS tube, this energy will be concentrated at the end of the soldering pen and heated through a short circuit. According to different configurations, the thickness can be around 0.1MM-0.15mm. Precisely controlled by the microcontroller program without triggering the switch. Circuit uses 12V battery and will become an energy storage spot welder for welding nickel sheets such as lithium batteries and nickel-chromium batteries.
