1. There is no display on the LCD screen when booting up. If you encounter this situation, you must first consider whether you can stop powering the pack battery automatic spot welding machine. If the power is ensured, but it still does not display, it may be a power failure. We can reflect on the power line to see if there is a short circuit. Maybe the fuse was burned. If this is the problem, we only need to change the insurance tube of different specifications.

　　2. It is displayed when the machine is turned on, but there is no response to welding. In this case, the charging fuse of the inverter spot welding machine is burned out, and it can be dealt with only by changing the fuse of different specifications.

　　3. There is power indication and no welding sparks. The pack battery automatic spot welding machine has many capabilities, the welding current parameter is too small; the distance between the lower end of the welding pin and the battery is too large; the welding switch is damaged; the photoelectric switch is damaged. There are possible reasons. Just need to change these results.

　　4. The pack battery automatic spot welding machine is easy to ignite or even burn the battery shell during welding. It may be because the pressure of the welding needle of the pneumatic spot welding machine is low; the lower end of the welding needle is stuck with foreign matter; the welding data is wrong; the welding current of the pack battery automatic spot welding machine is too large; the height of the two welding needles is not at the same level. If it is different, you can understand the result by reflecting on these abilities, and then have a goal.
