DH30 Portable Spot Welder Mini 18650 Spot Welding Machine (Silver) with Quick Release Welding Pens

DH30 Portable Spot Welder Mini 18650 Spot Welding Machine (Silver) with Quick Release Welding Pens

Attention:
- Full charging is needed before using!
- The two needles of the spot welding pen cannot be touched together, because the power will increase a lot when they touch each other, which will cause a short circuit and burn the machine.

Features:
- Portable spot welder with OLED screen enables firm solder joints
- Press the switch button for 3s to turn it on/off
- It will automatically power off
- Can be used to weld 0.1-0.15mm nickel sheets
- Output voltage: 4.2V (max). Output current: 650A (max). Design current: 1200A
- Designed with sufficient redundancy: the solder pen does not damage its circuitry when it is shorted. However, if the short-circuited current is large, it may affect the battery life
- With power bank function: It can be used while charging, which greatly improves work efficiency
- Firm solder joints: Can be used to weld cylindrical batteries. Support nickel, iron, copper, aluminum, steel sheets to weld all kinds of cylindrical batteries into groups
- Mobile phone batteries can also be soldered: support welding mainstream mobile phone batteries such as for Apple, Xiaomi and Vivo
- Long service life. Safer and more secure to use. With over-current protection, charge and discharge protection

Attention:
- Please ensure that the surface of the battery and the surface of the nickel sheet are clean and corrosion-free. And the surface of the nickel sheet should be flat.

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 to avoid MOSFET explosion. 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 solder joint 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 phone charging, so your phone cannot be charged temporarily. If you need to charge your phone, you can short-circuit 2 and 3 of the USB output port. And for android cellphone, mobile phone charging protocols are different, and it currently cannot all support fast charging protocols.
