How to Use:

Important Note: Fully charge the battery before use

• Spot Welding Power Setting: Start with the first gear and increase the power slowly until it can be welded. Do not increase the power if it can be welded. Avoid MOS bombs. The black solder joints indicate that the power is too high. When welding, press down the soldering pin lightly, and the nickel sheet and the battery can be bonded together. The harder you press, the less solid the welding will be. It will automatically trigger after pressing down for one second.
• Adapter Selection Requirements: The adapter requires 5V, 2A or more. If you don’t have such adapter, we recommend buying it at our store together to better charge the spot welder.
• USB Output Port Description: Because the internal circuit of the spot welding machine is different, there may be some compatibility issues with the phone charging, so the phone cannot be charged temporarily,if you need charger phone,you can Short-circuit 2 and 3 of the usb output port. And for android cellphone,mobile phone charging protocols are different, and currently cannot all support fast charging protocols.

Precaution:

1. It's recommended to weld nickel sheets below 0.15mm (Can welding 0.15mm).
2. It's recommended to weld when battery power over 70% for better welding effect.
3. Pay attention to the placement of the soldering pen,if the pressure of the soldering pen too loose,will break down the nickel sheet.
4. If the pressure of the soldering pen too tightly,the welding will be week.
