I can walk trough the menu normaly but when i finish there is E25 again.
Tryed in stick mode too.
Tryed to reset it but always, after few moments i turn it on, there is E25.
I am just afraid it can be connected with IGBT modules. They are expencive as hell.
Tomorow i will disassembe it with friend of mine and will try to see the situation inside.

Fingers crossed it’s nothing too bad. How old is the machine? If the serial number has rubbed off it sounds like it’s had a hard life

Thank you Brad. Hope its nothing bad too. It`s 4 years old.
Probably tomorow will start with disassemble. If we find the issue will write here for sure.

Well worth getting fixed then at only 4 years old.

Was it yours from new? Or preowned?

Surely at 4 years old the serial number and data plate should still be visable?

It is mine but it's my fault for giving the machine to others to use and who knows where they are put it down so it is all scratched.

For now it is diode on primary driver power unit. Somehow we managed to damage it. I have odered it and now wait.
So, when we replace it then goes voltage measurement on pc board wich contains the welding logic-sequence control and process control of the machine.
Diodes(4 of them) and IGBT(4 of them) on secondary rectifer are good and thanks god for that.
So, thats it for now.
