Lithium battery spot welding machines may experience various malfunctions during use, and the following are some common fault situations:
1. Weak solder joints: This may be due to incorrect welding current or time settings. If the current is too low or the time is too short, the welding point may not be firm enough.
2. Bubbles or holes appearing at the welding point: may be caused by surface contamination during welding (such as oxides, grease, etc.). Before welding, ensure that the welding surface is clean.
3. Excessive electrode wear: If the electrode is frequently replaced or worn too quickly, it may be due to improper selection of electrode materials, excessive electrode pressure, or improper welding parameter settings.
4. Welding deformation or melting: If there is deformation or melting of the welding material during the welding process, it may be due to high welding temperature or long welding time.

5. Unstable welding current: It may be caused by unstable welding power supply voltage, poor electrode connection, or electrode damage.
6. Welding electrode damage: The electrode may be damaged during prolonged and high-frequency use, such as deformation, fracture, or burning.
7. Welding machine malfunction: The welding machine itself may have malfunctions, such as control system failures, power supply failures, wiring connection problems, etc.
8. Other faults such as damaged welding fixtures, uneven welding heads, and unstable workpiece positions may also affect welding quality.
For these common faults, the following measures can be taken for troubleshooting and handling:
① Regularly inspect the condition of welding equipment and electrodes to ensure their proper functioning.
② Adjust welding parameters such as current, time, pressure, etc. to improve welding quality.
③ Clean and treat the welding surface to ensure it is free from contamination.
If there is a serious malfunction, promptly contact the manufacturer or professional technicians for repair and handling
