How to repair the malfunction of the electric welding machine

Oct 15, 2021

First of all, let's take a look at the problem of the electric welding machine. The power supply is not receiving power. Why is there no power? This is the problem of blown fuse or power interface. How to deal with this problem, we need to replace accessories or turn on the power from the beginning.

The second problem is that the display does not appear after booting, the screen flickers, and the machine beeps. The display may be damaged. The reasons for the damage of the display are exposure, heat, impact, aging, and disconnection of the circuit. This problem can be solved by rewiring and replacing the display.

The third is that the external power supply is undervoltage and the power cord is laid too long, causing the current of the electric welding machine to fail to rise. The external power connection must be checked and laid from scratch.

The fourth reason is that the power supply cannot work normally according to the set parameters. The segment current parameter is set too low. The method is to first increase the segment current parameter less than 30s, and then continue to weld the normal parameters

Fifth, the welding is abnormal. The heating element of the PB pipe is short-circuited, and the welding can be stopped and cooled before welding

Sixth, it shows that the output circuit is open, the resistance value exceeds the lower limit, and the PE pipe fitting is abnormal. Check P8 pipe fittings, replace pipe fittings from the beginning for welding

Seventh, the welding process is abnormal, and the connecting column heats up; the copper cap of the output wire is aging. Correct the copper cover or replace with new accessories from the beginning.

Eighth, the cause of overcurrent and overvoltage is the problem of the external power supply. The external power supply must be checked and connected from the beginning.

Ninth, the motor works, but the hydraulic push is invalid because the hydraulic oil has no nominal direction. You can check the hydraulic oil and choose regular hydraulic oil to replenish it.
