About This Product
This spot welder control board is a neat little PCB that lets you build or upgrade your own battery welding setup.
It supports operating voltages from 6.
5V up to 16V, with a peak current of 3600A – enough to weld 0.

1 to 0.
3mm nickel strips onto cylindrical batteries like 26650, 32650, Ni-MH, and Cd-Ni cells.

It's got 99 adjustable power levels, so you can fine-tune the weld for different materials and thicknesses.

There's a built-in 12-bit ADC for voltage measurement, accurate to 0.

01V, so you know exactly what's going on.

The display can switch between Chinese and English.

Standby power draw is just 0.
5mA, so it's efficient.

The package includes the mainboard, two soldering pens, an input cable, nickel sheets, screws, nuts, and a manual.
Great for hobbyists building battery packs for e-bikes, power tools, or DIY energy storage.

Compact and versatile, it turns a simple power source into a precision spot welder.
