4. Welding Process

This spot welder supports welding nickel-plated sheets up to 0.25mm, steel/iron sheets up to 0.2mm, and pure nickel sheets up to 0.15mm. It features intelligent recognition and fully automatic welding operation.

1. Ensure the battery is sufficiently charged.
2. Select the appropriate power level (gear) for your material thickness. Start with lower settings and increase if necessary.
3. Place the nickel strip and the battery/material to be welded on a stable, non-conductive surface.
4. Position the welding pins firmly onto the nickel strip, ensuring good contact with both the strip and the material underneath.
5. The device will automatically initiate the welding process.
6. Inspect the weld for strength and quality. Adjust power settings or pin pressure if needed.

Maintenance

• Cleaning: Regularly clean the welding pins and the device body with a dry, soft cloth. Ensure no debris or foreign objects accumulate around the welding pins.
• Storage: Store the spot welder in a cool, dry place away from direct sunlight and moisture.
• Battery Care: For long-term storage, charge the battery to approximately 50-70% capacity. Recharge every 3-6 months to maintain battery health.
• Pin Inspection: Periodically inspect the welding pins for wear or damage. Replace them if they become dull or corroded to ensure optimal welding performance.

Troubleshooting

User Tips

• For 18650 battery spot welding, users have reported better results when setting the power level to gear 8. Experiment with settings 6 and 7 if gear 8 is too strong for your specific application.
• Always perform test welds on scrap material before working on your main project to find the optimal power setting and technique.
