In the welding process of medium frequency spot welding machines, it is common to encounter problems such as welding failure and product defect rate, such as weak welding, severe splashing, serious material discoloration, electrode sticking, and severe electrode loss.

If we analyze carefully, we can find some reasons and make corrections. The main causes of faults in intermediate frequency spot welding machines are:

1、Material related:

Poor electroplating or dirty oxidation of workpieces, improper design of protruding parts, incorrect positioning of workpieces, and metal incompatibility.

2、Head related (pneumatic engine head and other downward pressure mechanism):

Poor tracking of welding joints, insufficient force application, incorrect polarity, and excessive force.

3、Electrode related:

Too long time, insufficient time, insufficient current rise slope, insufficient holding time, excessive current/energy, insufficient preloading time, insufficient current/energy.
