Is it possible to test contactor when it’s already installed in control panel? But, I’ll cut the main power from the Control panel; so I can do the test! Can I please?
Having the wrong ip rating for the machine can cause a contact weld as well. For example Working in dusty and wet conditions and your contactors only have an IP of 20. After 5 years they will start welding themselves shut.
Great explanation. I was looking for the follow up for this Video as you promised can't find it. May be it is somewhere, I do not know. I noticed a problem wit many but not all of educational content, promises are made and no follow up is made later on.
Interesting indeed

Is it possible a main contactor not working when in reverse polarity?
No. AC coil can work in both direction
If the contector on by itself how I can fix it
Check the coil supply. Something is there which energizes the coil. Rectify it. Otherwise there is no other way to turn it on
I use Relay , LCD ,PZEM004T,Arduino with 3 phase contactor and when I give power to contactor ,it flashover . how to stop flashover ?
Try to control EMI noise
Where is the next video , solutions of this failure?
