3GOA | 6 Gears Adjustable Mini Spot Welding Machine - used for quick spot welding, and ideal for welding the battery protection board on iPhone batteries.


As we know, for iPhone XS and above models, when a third-party battery or a genuine replacement battery is replaced by a third-party repair shop that isn't one of Apple's authorized partners, the battery health menu will show a warning about being unable to verify this iPhone has a genuine iPhone battery. The solution for this kind issue is to swap the original battery protection board to the new battery. This spot welder can be used to solder the battery protection board to solve this problem.

2. 40cm welding pen cable for more flexible operation
3. Level 1 to level 6, adjustable 6-level power for more precise soldering
