DIY Portable Battery Spot Welder 18650 Energy Storage Spot Solder PCB Circuit Board Control Welding

Comes with a charging control module, which can charge the battery through the USB port, and is fully with 0.1mm-0.12mm internal nickel-plated sheet to weld multiple solder jointsIt is precisely controlled by the Single Chip Microcomputer Program without flipping the switch.Self-transporting with a charge control module, which charges the battery through the USB port.Through the output of the MOS tube, this energy will be concentrated on the tip of the soldering pen, and the nickel sheet will be firmly fused with the battery by means of short-circuit heating. All this will happen in a few milliseconds, completely freeing your fingers or pedals.1. The spot welder supports nickel sheets with an inner thickness of 0.12mm, which has strong adhesion.
