Old semi-automatic welding machine - device identification

[Nix2]

Hello
A friend has an old semi-automatic welding machine, probably of German production, unfortunately with a completely illegible nameplate ... Maybe someone recognizes what brand and model it is?

The auxiliary transformer burned in it, hence I am looking for a diagram and transformer data (I want to match another, new transformer)

Regards !

This one is from the same manufacturer,
maybe yours is a little less powerful and older,
or is this an older, well-preserved copy...

That machine is in amazing condition. Did it spend it's life in a museum, inside a glass case?

Yes, they look the same, now I'm talking about the parameters (voltage, because the size is estimated at about 100-120VA) of the auxiliary transformer. Or maybe there will be a diagram with the transformer voltage markings?

I took a picture of that machine two years ago, and I don't know how it looks now.
I think it's still in my place, unfortunately I don't have the owner's phone anymore.
When I took a picture of him, it looked like as eddie49 said it spend it's life in a museum, inside a glass case.
Probably not used after purchase.
