About This Product
This portable mini spot welder is perfect for building or repairing battery packs, especially with 18650 cells.
It’s a compact unit that delivers quick pulses of power to spot weld nickel strips to battery terminals.
Great for DIY power walls, e-bike batteries, or any project needing custom battery assemblies.
It’s unbranded but functional, and brand new.
The kit includes the welder unit and probably the leads (double-check listing for included parts).
It runs on a power supply or capacitor bank — typical for these small welders.
If you’re into electronics, vaping mods, or electric vehicles, this tool saves money over pre-built packs.
Easy to use with a little practice.
Just set the nickel strip, press the probes, and weld.
No gas, no filler rod — just clean electrical welds.
Good for hobbyists and makers.
MPN and UPC not applicable, but it’s a common type sold under many names.
Grab it and start building.
