Description:
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. Remove the circuit board, use a soldering iron to solder the buzzer (long feet positive, short feet negative) and handle the soldering ports to avoid puncturing the battery after installation;
3. The copper ear of the black soldering pen is connected to the upper surface of the circuit board by M5 screws, and the copper ear of the red soldering pen is connected to the positive electrode of the battery (the back of the circuit board);
4. Fully charge through the USB cable after assembly (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);
5. 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.
