6:39 check your gate circuit , theres burnt resistors on the drive, i always verify good gate waveform now before installing a new clip. I hate turning an a new repair and realising i just pulled the trigger on an ak47 as the igbts explode in quick succession. (Clip reference probably makes sense now)
If these do blow then there is more trouble present, like the dead time or the gate drive, so watch these on a scope, you can look what chip do drive the igbt and recalculate deadtime if that is to small.
I too have a same welding machine but don't in sudden it's not working. Display is working fine and I tried in many ways but no use. Can you please help me with this issue
Thanks for the informative video and sharing how to test a igbt
Igbt testing technique is very good and like a practical test
Thank you for sharing this video really informative .
GOOD TICHING KARTE HO AP THANKS 👍👌👌👍👌👍👌👍

Good but explain to your voice resistance value is not showing clear
Sir mera Belding machine ka IGBT 60N60 bar bar kharab ho raha hai kya karu
