Review on 🔌 Portable Spot Welder Machine, Kerpu Mini Spot Welder with Energy Storage 5000mAh for DIY 18650 Battery, Spot Welding Equipment. Type-C Port 2A Input, Portable Battery Welder. by Lamar Vanderburg

For repairing battery packs for power tools. The factory welds on my batteries are very strong and require pliers (Dewalt batteries) to remove. This device makes pretty good spot welds, but I can easily remove the welds by hand with enough force. The product is very easy to use. From my own experience it seems better to me to use a medium setting range of 3-5 and leave 1 welding tip on the band and dot over it 2-3 more times. I once tried different ways of spot welding, but I did 6-8 seams per 1 battery. Easily given. If you use maximum power on the same weld, it will burn out completely. Pressing too lightly creates a hole in the nickel. Using 2-3 spot welds The same spot made for the best weld was very difficult to remove but for some reason only one side was solid. when i make battery packs adjust 6-8 welds. The best advice I have for using this device is to place one tip on the item to be welded with your non-dominant hand and then place the other tip with your dominant hand for more stability. . The cables are very short, but that helps a lot. I tried using a little pressure and my welds were bad. I think what they mean by pressure is not trying to spank him. It is enough that the nickel strip touches the battery. Keep the tips closed, but don't close them, it seems like the farther apart they were, the easier they ripped off. I hope someone finds this review useful. If I don't like this spot welder, I'll try kweld, ahaha.
