Old Cloos welder

[Kenterfur]

Recently got this old German made Carl Cloos welder, think it's from the 60s.
It's technically working but it needs to be rewired since someone has tampered with the electronics and wiring inside.
I'm currently in the process of drawing and tracing out all the wires in hopes I'll be able to bring order to it.
I'm posting here in hopes that someone has this welder, some manuals, experience or any advice on this old Cloos welder. Unfortunately there isn't a model number anywhere to be seen and I haven't even found mention of this welder anywhere on the Internet, but perhaps the photograph will be enough for someone to recognise it and mayhaps help.
Thank you

Hello and welcome to the Forum !

That is a really great-looking old welder! It actually may not be so old - these two Cloos machines are from the 1990's :

Welcome to the forum.

That looks a beast, I take it the cylinder is an oil filled transformer and the control gear is in the red box on top?

If you post some pics of the inside of the red box one of us will be able to help decipher it.

It isn’t oil cooled.
The control is on top of the cylinder.
They can get tricky….

You need to have a look at the phases because the fan (inside the cylinder) is observed.

Wait a minute.
I try to find some information.

I had to integrate a couple of Cloos welders to robots about 20 years ago, they had very little UK support and wouldn't release any wiring info, we had to pay for an engineer to come to the unit and show us the drawings, at least he was OK and turned a blind eye while I photocopied the drawings.

Here you go.

Thank you very much for the schematics! If it were not for them I probobly would have had a lot more miserable time before realising the issue was in the "wind detector" a small switch with a flag to detect airflow to check if the main ventilator is working, on top of that the previous owners also hadn't realised that that was the issue and had manually added wires to bypass it. Really thanks
