How much do you know about the maintenance of butt welding machines

The butt welding machine needs regular inspection and maintenance to extend the work efficiency and welding speed. If a large-scale production of any equipment is not performed regularly, it will cause irreparable damage to the equipment. The editor introduces the troubleshooting for everyone:

 1. Thyristor Thru Fault: When the controller has no output, it detects that the thyristor is single or double

Solution: Check whether the thyristor is damaged and the wiring is correct.

2. Thyristor does not turn on. Fault: When the controller outputs a pulse, it detects that the thyristor is single or double cut off.

Solution: Check whether the thyristor is damaged and whether the wiring of terminals 3, 4, 5, and 6 is correct. Please exchange the wiring of controller power supply 7 and 8.

3. Overheating failure: When the external thermal protection switch is connected, the switch operates or is abnormal.

Solution: Whether the thermal protection device is working (whether it is really overheating) Whether the AA setting is correct.

4. Undercurrent Fault: Welding current is too small

Solution: Whether the AL setting is correct (such as the parameter setting is too small) The workpiece is not placed or is not in good contact. The current setting value exceeds the transformer maximum current.

5. The transformer's measuring range is too large. Fault: The sampling current is small.

Solution: Replace the transformer with smaller range.

6. Memory data error Fault: Controller parameter setting is incorrect

Solution: Check parameter settings.

7. No synchronization signal Fault: Synchronization signal is lost

Solution: Check whether the wiring matches the wiring diagram.
