What are some common control unit failures and their solutions for motor motor rotor (single station) spot welder?

Motor motor rotor (single station) spot welding machine in the operation process may encounter some common control unit faults and their solutions are as follows:

1, the current is not stable:

Failure causes: may be unstable power supply voltage or welding control board, regulator failure.

Solution: Check whether the power supply voltage is normal, if the voltage is normal, you need to check whether the welding control board or regulator is working properly.

2, spot welder does not work, the power indicator does not light:

Failure causes: may be the power supply voltage is not normal or the control system is abnormal.

Solution: Check whether the power supply voltage is normal, check whether the control system is working properly.

3、Welding with undue spatter:

Failure causes: may be a serious oxidation of the electrode head or welding workpiece serious corrosion poor contact.

Solution: Check whether the electrode head is oxidized seriously, check whether the welding workpiece is seriously rusted poor contact, and clean up and maintain accordingly.

4、Welding spot indentation is serious and extrusion:

Failure causes: may be too much current or electrode pressure.

Solution: Check whether the current is too large, check whether the electrode pressure is too large, and adjust accordingly.

5、Ac contactor rattles abnormally during welding:

Failure causes: may be the AC contactor into the line voltage is lower than its own release voltage or power leads too thin and too long resulting in too much line voltage drop.

Solution: Check whether the AC contactor inlet voltage is lower than its own release voltage of 300 volts, check whether the power supply lead is too thin and too long, and adjust accordingly.

The above are some motor rotor spot welding machine in the operation process may encounter control unit failure and its solutions, specific problems may require more detailed diagnosis and professional maintenance.
