Operating a Lithium Battery Spot Welder

1. Adjust the current to 20A for pneumatic lithium battery spot welder before power on, the current should be 40A for foot operated lithium battery spot welder.
2. The top of the machine needs to left 4-5 screw threads to ensure sufficient pressure for spot welding work.
3. Adjust the distance between the welding needle and the lithium battery to 5mm or so, which is almost enough for a wrench to put in.
4. The working pressure should be touch 0.3-0.5pa.
5. Fix the welding needles, there are two welding needles, do double pulse spot welding to ensure weld firmly.
6. Then try to weld the battery and test the firm performance. If not good, then can adjust the current to a higher one. After testing, then can do normal work.

Maintenance

Regular maintenance includes cleaning the electrode tips, checking the electrical connections, and ensuring the control system is functioning properly.

Conclusion

Lithium Battery Spot Welders are resistance pulse welding machines in China, which are essential tools in the field of battery technology, offering the precision and control required for effective and safe lithium battery assembly and repair. Their ability to deliver consistent and reliable spot welds makes them invaluable in applications ranging from electric vehicle manufacturing to consumer electronics. Proper operation and adherence to safety protocols are crucial to ensure effective and safe use of the equipment.
