4. Operating Instructions

4.1 Powering On/Off

To power on the device, press and hold the power button (located on the base) for two seconds. The LED display will illuminate. To power off, press and hold the power button again for two seconds.

4.2 Adjusting Power Levels

The spot welder features 8 adjustable power levels. After turning on the device, each short press of the power button will cycle through the speed settings from 1 to 8. After reaching speed 8, it resets to speed 1. Select the appropriate power level based on the material thickness you are welding.

4.3 Using LED Lighting

The device has a 3-level adjustable LED light. Short press the light switch button (located on the base) to cycle through the brightness levels (low, medium, high, off).

4.4 Welding Process

1. Ensure the welding needles are clean and properly installed.
2. Select the desired power level.
3. Place the nickel strip or material to be welded onto the battery terminal or workpiece.
4. Firmly press the two welding needles onto the nickel strip, ensuring good contact with both the strip and the underlying material.
5. The device will automatically trigger a weld when proper contact is made. You will see a spark and hear a click.
6. Lift the welder and inspect the weld. Adjust power levels if necessary for stronger or cleaner welds.

4.5 Material Compatibility and Thickness

The Airepair spot welder is capable of welding various materials with specific maximum thicknesses:

• Nickel-plated sheets: Up to 0.25 mm (max)
• Steel sheets: Up to 0.2 mm (max)
• Sheet metal (general): Up to 0.2 mm (max)
• Pure nickel sheets: Up to 0.15 mm (max)

5. Maintenance

5.1 Cleaning

Regularly inspect and clean the welding needles. Remove any residue or oxidation using fine sandpaper or a wire brush to ensure optimal conductivity and welding performance. Keep the device body clean with a dry cloth.

5.2 Storage

Store the spot welder in a cool, dry place away from direct sunlight and moisture. Ensure the device is powered off before storing. If storing for extended periods, it is recommended to charge the battery to about 50% to prolong battery life.

5.3 Replacing Welding Needles

If the welding needles become worn or damaged, they can be replaced. Follow the installation steps in Section 3.2 to remove the old needles and install new ones.

6. Troubleshooting

• Device Fails to Power On: This may be due to low battery power or a faulty motherboard. First, verify that the charging cable and charger are correctly connected and functioning.
• Device Powers On but Does Not Weld: Inspect both soldering pins for any foreign objects causing a short circuit. Ensure the device is properly switched to welding mode (if applicable, though this model is automatic).
• LED Lighting Not Working: Check if the LED light setting is in the 'off' state (level 0). Cycle through the light settings to activate it.
• Sudden Shutdown During Operation: Prolonged high-power consumption can cause internal overheating, triggering a protective shutdown. Allow the device to cool down for a while before attempting to restart.

8. User Tips

• Always perform a test weld on scrap material before working on your main project to find the optimal power setting.
• Ensure the welding area is clean and free of debris for the best weld quality.
• Apply firm, even pressure on the welding needles to ensure good contact and prevent weak welds.
• For consistent results, try to maintain a consistent angle and pressure during each weld.
