Welding Tips and Tricks

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 only chance is to find another persons who have this machine and to make a photo of this missing pcb 650.5130.0 pc-board GLE, an tomake a schematic from this photo

The current lineup of Lorch are very nice power supplies. Hope you get it figured out and repaired..

For moment i can't make him, because i don't find this module at good price. At a local dealers of lorch in my country the price of module is ~450E with TVA. At this price it's not oportunity to make him.
I think the last chance is to find a user who have this model machine and to make a good photos of this module from side/back side of a pcb and to make a reverse engineering.

Due to obsolescence, sometimes it’s time to abandon not so old machines.

I suggest you to give a call during holidays, even in large companies you can sometime join a higher ranked person that way, one that can afford to send you detailed manual of sketch of a disrupted model, of that will try to help you as it is not its primary function.

I think ..i have to wait some time and to find one with another probleme and to take this module

I'm searching for the schematic/diagram of this module or to buy another one from a defective machine.
