12V DIY Portable Spot Welding Machine PCB Circuit Board For Li-ion and LiFePO4 batteries – Pre Assembled

12V DIY Portable Spot Welding Machine Battery Storage PCB Circuit Board includes an Electronic Welding Module that is an important part. Spot welding is welded by the principle of rapid local heating and cooling by high current. It will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries practical, easy to operate and use wide application range, and has a long service life. Features: Lightweight and portable, stable and reliable, wear-resistant, and can provide long service time. There is a window on the back of the drive part, you can add copper or tin by yourself. The external pads for the LED and the onboard buttons are added to facilitate the connection of the LEDs and buttons on the board to other places. Suitable for welding 18650/26650/32650 battery.Note:  We recommend using a High current Battery source of 160AH with this module as all spot welding machines need a high current for weldingPackage Includes: 1 x 12V DIY Portable Spot Welding Machine PCB Circuit Board For Li-ion and LiFePO4 batteries Note: Circuit Design and color may vary from Images and this item comes Pre soldered and assembled.
