5. Setup and Assembly
5.1 Charging the Device
Before first use, ensure the spot welder is fully charged. Connect the provided Type-C charging cable to the device and a compatible 5V/2.1A power source. The device can be charged and used simultaneously.
5.2 Welding Pin Replacement and Adjustment
The welding pins are replaceable and their spacing is adjustable to suit different welding needs.
- Loosen Screws: Loosen the fixing screws of the welding pins on both sides of the device.
- Remove Pin: Carefully remove the old soldering pin along its direction.
- Install New Pin & Adjust Spacing: Install the new soldering pins. Adjust the spacing between 0.5mm and 3mm by moving the welding needles up or down as needed.
- Tighten Screws: Once the desired spacing is achieved, tighten the fixing screws on both sides to secure the pins.
Note: To disassemble and replace the needle, use a 3mm outer diameter cross screwdriver. Forcibly removing screws without proper tools may damage the shell.
