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

• --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.
