Mini 18650 Battery Spot Welder Welding Machine For 0.1mm-0.15mm Nickel Sheet (Powered by 2 Battery)

Mini 18650 Battery Spot Welder Welding Machine For 0.1mm-0.15mm Nickel Sheet (Powered by 2 Battery)

Description:
Equipped with 3.7-4.2V, 5000mA power lithium battery, discharge rate is 65C, output capacity is about 300A. Through the output of MOS tube, this energy will be concentrated at the end of the welding pen. By short-circuit heating, nickel sheet is firmly fused with your battery. All this will happen within a few milliseconds. Accurately controlled by MCU, without triggering the switch, it completely free your fingers or foot pedal.

Technical Points:
- 3.7-4.2V 4.5aH power lithium battery
- Discharge rate of 100C
- Load capacity of about 400A

Features:
- Safe and reliable to use with low voltage
- With charging control module
- MCU enables precise control, triggering switch is not needed
- Weld hundreds of solder joints for commonly used nickel-plated sheets of 0.1-0.15mm

Specifications:
- Item Name: Mini spot welding machine
- Output Current: 300 A
- Product Size: 200 x 80 x 20 mm
- Weight: 450 g
- Welded Thickness: 0.1-0.15mm

Package Included:
- 1 x Set of Battery Spot Welder

Note: 18650 batteries are not included in the package.

Using Method:
- Solder buzzer first. Please pay attention to the polarity.
- Weld the negative wire at the negative output. If there is no high-power soldering iron, you can use a furnace to heat the soldering iron to increase the soldering temperature.
- Fix battery on the back of the circuit and fix it with screws. At the same time, fix the positive wire lug. Please pay attention to the polarity to prevent short circuit of the circuit board copper foil and components.
- Fully charge after assembly. To ensure the durability of battery, we set a lower charging current. The charging process is about 4 hours. When it is charging, red light is on. When fully charged, the green light is on.
