Common maintenance methods for spot welding machines

spot welding machine for everyone to popularize, spot welding machine repair knowledge. Spot welding machine in the automotive and sheet metal industry use more and more common, then the problem comes, we are in the maintenance and maintenance of how to repair it? The following science and technology Xiaobian to talk about the spot welding machine commonly used repair method:

1, visual inspection

visual inspection of this kind of fault is mainly by eye and ear to hear, that is, audio-visual inspection. For example: fuse, broken wire, connector fall off, electrode aging, etc.

2, Power Supply Check

When the fault cannot be eliminated after the visual check is completed, the power supply check can be carried out. By using a multimeter to measure the input and output voltage of the control transformer, the power supply voltage; use an oscilloscope to measure the waveform of the test point, etc., to check the location of the fault and carry out maintenance.

3, Substitution Method

If conditions permit, a normal solder resist controller can be used to replace it first to determine the specific location of the fault and quickly check the cause of the fault. Even if the cause of the failure cannot be found immediately, the inspection scope of the failure can be reduced to avoid wasting unnecessary inspection time.
