Comes with a charging control module, which can charge the battery through the USB port, and is fully charged with 0.1mm-0.15mm internal nickel-plated sheet to weld multiple solder joints.
It is precisely controlled by the Single Chip Microcomputer Program without flipping the switch.
Self-transporting with a charge control module, which charges the battery through the USB port.
It is equipped with 3.7-4.2V 5000mA lithium battery, the discharge rate is 65C, and the output capacity is about 300A.
Through the output of the MOS tube, this energy will be concentrated on the tip of the soldering pen, and the nickel sheet will be firmly fused with the battery by means of short-circuit heating. All this will happen in a few milliseconds, completely freeing your fingers or pedals.


Color: Green + Black
Material: Metal
Size: 124x80x18mm

Installation steps and matters needing attention:

1. To operate this product, you need to have considerable electrical knowledge. Do not short-circuit or reverse the electrodes, otherwise the 300A short-circuit current will make you doubt your life.
2. The copper ear of the black soldering pens is connected to the upper surface of the circuit board by M5 screws, and the copper ear of the red soldering pens is connected to the positive electrode of the battery (the back of the circuit board)
3. Fully charge through the USB cable after assembly (in order to ensure the durability of the battery, we set a lower charging current, the charging process is about 4 hours, the red light is on when charging, and the light is fully turned to green)
4. After the battery is connected, the circuit board defaults to the on state and automatically shuts down after a delay of about 10 minutes. Press the switch to turn on and select the welding current intensity.
6. Each time you press the button, the switch will realize the following functions (di-low current, didi-medium current, dididi-high current, shutdown)


Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
