Spot Welder DIY Kit Portable 12v Battery Energy Storage Spot Welding Machine PCB Circuit Board Soldering Equipment

Features: Lightweight and portable, stable and reliable, wear-resistant, and long service life. Through the MOS tube output, this energy will be concentrated on the end of the soldering pen, short-circuit heating. Firmly fuse the nickel sheet with the battery. And it is precisely controlled by the MCU program without triggering the switch. Suitable for welding 18650/26650/32650 batteries. The welding current is about 90-130A, which is more than enough for welding ordinary 0.1mm-0.12mm nickel plates. Upgraded to an automatic trigger design, no longer need to press the button for a long time, completely free your hands. Battery recommendation: 20-45ah lead-acid battery, with excellent performance and low internal resistance. 3.5-5.5ah 3s 45C lithium polymer battery pack. 30-35ah 18650 lithium battery pack.
