It's OK now. The inverter works well. It was most likely a command problem. I just have to find a 2k2 potentiometer like the original one who have the hole in the center, to replace original because he has a brocken pinout.
After an e-mail discussion with a HELPDESK@lorch.eu, I realized that there would be another pcb-level manual service for those inverter component modules relative to that handbook in German but he haven’t the permission to send out detailed electrical schematics of the pcb’s...so i think the...
For moment my idea is to resolve with this and...if not work after change this pbc maybe i buy another but i don't wanna loose some money with ESAB and another made in china but like made in europe. Maybe my Lorch is oldie but goodie... and a inverter what can use at 230/400v. The inverter...

I need a internal photo backside of a front panel if anyone...
After i send a mail to The Lincoln Electric Company, i receive a mail with a precious help so i have a schematic of this machine. Maybe someone have like me need a help someday, so i upload a arhive with this schematic

my invertor don't have the pcb or something underside of front case like these in photo.
In attached photo, in front of case are 2 potentiometer one for current and...
I'm from Romania

I have a deffective comand pcb problem and my serial number from back side it's broken (it's like 344-1047....012) so i need a service manual for him but without a complete serial can't find one in...
