6. Operating Instructions
6.1 Powering On/Off
Press and hold the power button to turn the device on or off. The digital display will illuminate upon power-on.
6.2 Adjusting Welding Parameters
Use the control buttons to navigate through the settings on the high-definition digital display. You can adjust:
- Gear (Power Level): Select from 90 levels of power adjustment. Start with lower settings and gradually increase as needed for your material.
- Preheat Time: Adjust the preheating duration for optimal welding results, especially with thicker materials.
- Trigger Time: Set the duration of the welding pulse.
- Mode: Switch between Automatic and Manual welding modes.
6.3 Welding Procedure
- Prepare your workpiece: Ensure the nickel strip and battery terminals are clean and free of oxidation. Use sandpaper if necessary.
- Place the nickel strip firmly against the battery terminal.
- Position the welding pins squarely onto the nickel strip, ensuring both pins make good contact.
- In Automatic Mode, the device will detect contact and automatically trigger the weld after a short delay.
- In Manual Mode, press the trigger button (if available, or apply pressure until weld initiates) to perform the weld.
- After welding, lift the pins straight up to avoid damaging the weld.
- Inspect the weld for strength and consistency. Adjust gear settings if the weld is too weak or too strong.

7. Maintenance
7.1 Cleaning
Regularly clean the welding pins and the device casing. Use a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure no metal dust or debris accumulates around the welding pins.
7.2 Pin Replacement
Over time, the alumina copper solder pins may wear down. Replace them with new pins from the spare set provided or purchase genuine replacements. Refer to Section 5.2 for pin installation instructions.
7.3 Storage
Store the spot welder in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the device is powered off before storage.
8. Troubleshooting
- No Weld/Weak Weld:
- Check battery charge level. Recharge if low.
- Increase the gear (power) setting.
- Ensure welding pins are clean and making good contact with both the nickel strip and battery.
- Verify the nickel strip and battery terminals are clean.
- Adjust preheat and trigger times. - Overheating:
- Allow the device to cool down. The display shows real-time temperature monitoring.
- Reduce the frequency of welds. - Device Not Powering On:
- Ensure the device is fully charged.
- Check the Type-C charging cable and power adapter. - Inconsistent Welds:
- Ensure consistent pressure is applied to the welding pins.
- Check for worn or damaged welding pins.
- Verify stable power supply from the internal battery.
If problems persist, contact customer support.
