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.
