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 Junior Samson

At first he couldn't even weld the nickel strips provided. I bent the copper contacts on the ends of the probes to fit the welder snugly, polished the working ends a bit, and used a light touch. 3 and 4 installations were enough, then everything worked perfectly. I replaced some cells in my i8650 e-bike battery. However, it is not suitable for tapes with a thickness of 0.20 or 0.15 mm. He has no power. I have ordered some 0.10mm and am hoping it will look like the one that came with the welder. I repaired two batteries with this stuff and it leaked when I was assembling a full battery. Due to the thinner strips I have to use two coats.
