This is a kind of fine quality welding circuit board, suitable for welding 18650/26650/32650 battery. The welding current approx. 90-130A, which is more than enough to welding common 0.1mm-0.12mm nickel plate. Upgraded to automatic triggered design, do not need to press button for long time anymore, completely frees your hands. You can have a try.

Features:
Lightweight and portable, stable and reliable, wear resistant and can provides long service time.
Through the MOS tube output, this energy will be concentrated at the end of the welding pen, and it will be heated by short circuit.
Fuse the nickel sheet firmly with the battery.
And it is precisely controlled by the single-chip microcomputer program without trigger switch.
