Review on Adjustable 9 Gears Mini Spot Welding Machine - Portable DIY Spot Welder with Quick Release Pen for 18650 Battery Plate Spot Welding, Includes Nickel Sheet and Charging Cable by Eric Broad

It comes up to the highest settings, ready to do the trick. No need for a pedal, it feels the material and explodes. Unfortunately I managed to weld the battery tab to my cast iron table saw. Interestingly, it was not possible to weld the battery cable directly to the copper tube. So it seems best to weld materials that don't transfer heat very quickly. If you only touch the nickel strip of the battery, it glows from contact to contact. Update: Other components of my battery have arrived and I was disappointed. This only works with very thin nickel strips. On strips of 0.2 mm did not work at all. Therefore, before buying, check the thickness of the strip.
