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 interior of the equipment. The editor will introduce the troubleshooting for everyone:
1. Thyristor shoot-through failure: When the controller has no output, a single or dual thyristor is detected to be conducting
Solution: Check whether the SCR is damaged and the wiring is correct.
2. Thyristor non-conducting fault: When the controller outputs a pulse, it detects that the thyristor single or double tube is cut off.
Solution: Check whether the thyristor is damaged and whether the terminals 3, 4, 5, and 6 are connected correctly. Please exchange the controller power supply wires 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 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. Excessive transformer range: small sampling current
Solution: Replace the transformer with smaller range.
6. Memory data error: controller parameter setting is incorrect
Solution: Check parameter settings.
7. No synchronization signal failure: synchronization signal is lost
Solution: Check whether the wiring matches the wiring diagram.
