For iPhone 13-14 Pro Max QianLi Macaron Generation 2 Portable Battery Spot Welding Machine

1. Material: Aluminum alloy2. Output Voltage: 4.2V (Max)3. Output Current: 650A (Max)4. Input interface: Type-C charging cable5. Battery Type: Rechargeable polymer lithium battery6. Recommended nickel thickness: 0.1~0.12mm7. Brand new upgraded cable, pure copper tips, more convenient compared to the previous generation8. The newly added interface provides more functions, newly added USB interface, so the device can also be used as a power bank9. Support welding 0.1-0.12 mm nickel all the time, to have it, save your time/effort10. Pure copper+golden plated processing, abrasion antirust resistant, low internal resistance11. Built-in high rate of power lithium battery, discharge max 650A12. Compatible battery 18650 and other cylinder-shaped, NI-MH battery cadmium nickel battery, etc13. It is a total of 6 gears of output power, is easily adjustable, for precise welding; and there are LED lights to indicate the working gear14. Good performance: welding pen, with gold-plate terminal, long enough, flexible to use, quick to install, fine conductivity, ensures beautiful welding spots15. Safe, reliable use: the welding machine has low voltage, over-current and over-charge protection, low battery alarm function, and auto-off under low power16. Power bank function: built-in rechargeable battery, 1000mAh high capacity, supports it to fast charge the mobile devices via 5V 2A USB port, very convenient17. Not compatible copper, aluminum, tin, and soft pack battery materials can not be soldered, even to nickel. To solder these materials lasers or ultrasonic need to be used18. Welding result depends on the welding skills Iron, and steel, the thickness of which is less than 0.12mm could be welded to other iron and stainless steel materials but we don't guarantee it would work
