How many maintenance methods are there for intermediate frequency spot welding machines?

How many maintenance methods are there for intermediate frequency spot welding machines? There are four types: 1. Visual inspection; 2. Power supply inspection; 3. Power supply inspection; 4. Empirical method. Below is a detailed introduction for everyone:

1. Visual inspection

The visual inspection of such faults mainly relies on visual and auditory inspection. For example: fuse melting, wire breakage, connector detachment, electrode aging, etc.

2. Power supply inspection

When the visual inspection is completed and the fault cannot be eliminated, a power supply inspection can be carried out. Measure the input, output voltage, and power supply voltage of the control transformer using a multimeter; Measure the waveform of the test point using an oscilloscope, identify the location of the fault, and repair it.

3. Power supply inspection

If conditions permit, a normal solder mask controller can be used as a substitute to determine the specific location of the fault and quickly identify the cause of the fault. Even if the cause of the malfunction cannot be immediately identified, the scope of the fault inspection can be narrowed down to avoid wasting unnecessary inspection time.

4. Empirical method

Repair personnel should memorize the fault phenomena and troubleshooting methods introduced in the “Repair Guide” of the welding machine user manual. And, accumulate and timely summarize the causes and troubleshooting methods of previous failures. When similar faults occur again, you can use the troubleshooting methods in the manual or previous repair experience to quickly identify and eliminate the fault point.
