5. Setup

1. Install Welding Pins: Insert the two copper welding pins into the designated slots at the front of the device.
2. Adjust Pin Spacing: Use the provided screwdriver to adjust the spacing of the welding pins. Turn the screw counter-clockwise to loosen and adjust, then clockwise to tighten and fix the pins in place. Ensure the pins are securely fastened and properly aligned for optimal welding.

6. Operating Instructions

1. Power On/Off: Press and hold the power button for 1 second to turn the device on. To turn it off, press and hold the power button for 1 second again.
2. Adjusting Power Levels: After powering on, short press the power button to cycle through the 8 power levels. Level 1 is the lowest power, and Level 8 is the highest. Select the appropriate level based on the material thickness and type.
3. Adjusting LED Lighting: After powering on, press the dedicated light switch button to cycle through 3 brightness levels. The device will remember the last brightness setting when powered off. Level 0 is off, Level 1 is 50% brightness, Level 2 is 70% brightness, and Level 3 is 100% brightness.
4. Performing a Spot Weld:
   • Ensure the battery and nickel strip are clean and free of oxidation. Use the included sandpaper if necessary.
   • Place the nickel strip firmly onto the battery terminal where you intend to weld.
   • Position the welding pins onto the nickel strip, ensuring both pins make good contact with the strip and are evenly spaced.
   • Apply firm, even pressure to the spot welder. The device will automatically detect contact and initiate the weld.
   • Lift the spot welder once the weld is complete. Inspect the weld for strength and quality.

7. Charging

The device is charged via a Type-C port (DC5V/2A input).

• Connect the provided Type-C charging cable to the device and a suitable USB power adapter.
• During charging, the battery level indicators on the base will display a running light (marquee effect).
• Once fully charged, all LED lights on the battery level indicator will remain steadily lit.
• Battery level indicators: The four LEDs represent battery levels: <25%, 25%-50%, 50%-75%, 75%-100%.

8. Maintenance

• Cleaning: Regularly clean the welding pins and the area around them to prevent buildup of debris or oxidation. Use a soft, dry cloth.
• Pin Replacement: If the welding pins become worn or damaged, they can be replaced. Follow the instructions in the Setup section to remove and install new pins.
• Storage: Store the device in a cool, dry place away from direct sunlight and moisture when not in use. Ensure the battery is partially charged (around 50%) for long-term storage.

9. Troubleshooting

• Device does not power on:
  • Check if the battery is sufficiently charged.
  • Ensure the charging cable and adapter are functioning correctly.
  • If the issue persists, there might be a motherboard failure (contact support).
• Device powers on but does not weld:
  • Inspect the welding needles for any foreign objects causing a short circuit.
  • Verify that the device is switched to a welding mode (power level 1-8).
  • Ensure good contact between the welding pins, nickel strip, and battery.
• LED lighting does not illuminate:
  • Check if the brightness level is set to "0" (off position). Adjust using the light switch button.
• Device suddenly shuts down during operation:
  • This is likely due to prolonged high-power use, triggering the overheat protection. Allow the device to cool down completely before attempting to restart it.

11. User Tips

• For best results, always ensure the nickel strip and battery terminals are clean. A quick scrub with sandpaper can improve conductivity.
• Experiment with different power levels on scrap material before working on your main project to find the optimal setting.
• Apply consistent, firm pressure when welding. Uneven pressure can lead to weak welds.
• If you're new to spot welding, practice on spare batteries and nickel strips to get a feel for the device.
• Keep the welding pins sharp and clean. Replace them if they show significant wear or pitting.
