Questions about this product

What is this spot welding pen mainly used for?
This hand-held tool is designed to build and repair custom battery packs by welding nickel strips to lithium-ion cells. It is perfect for making e-bike packs, rebuilding power tool batteries, and completing DIY electronics projects. The automatic trigger fires when you apply pressure, making clean connections without traditional soldering heat.
How thick of a nickel strip can this welder handle?
This mini spot welder typically handles nickel strips between 0.1 mm and 0.2 mm thick. Trying to weld materials thicker than this range might result in weak, unreliable joints. It delivers pulsed DC power optimized for these standard battery connection thicknesses.
Will this welding pen work with batteries other than 18650 cells?
Yes, you can use it on other cylindrical lithium-ion cells like 21700 or 26650 sizes. The dual-tip electrode configuration works on any standard battery cell that uses nickel strip connections. Just ensure your battery chemistry and terminal metal are compatible with spot welding.
