I don't know the model you refer too, but I believe Interlas was a Dutch company which later became part of ITW who also own Miller. So chances are its a Miller tig. Can you post some pictures of the actual unit?

thanks for the reply-will post a photo later on tonight,it's preety old early 80s as a guess.

just shows how little I know about welders(I thought it was a small tig welder)-looking at it and looking on the net it seems it's some sort of rectifier or a unit to change an arc welder into a tig.here's some photos:

That looks like a tig add on unit, I have a 200A Viper add on which looks very similar.

Yes, it is a HF box for a DC arc welder to add a contactor, HF arc, gas valve and water valve.

The HF generator looks just like my old car coil

if this thing works-what sort of power arc welder would I need to weld 3mm aluminium?
would I just need the same amps as a tig welder or does the rectifier change the amps in ac?

would you consider selling it?

what does this connect to?

As Scott said, it is an add-on HF Tig box for a DC arc welder. The inputs at the back are labelled + and -, so your "Arc Welder" will have to be a DC Welding Power Source, not an AC buzz box or an oil-cooled Oxford, and you will not be able to Tig aluminium with it.

Looks like the return for the water cooling circuit, the one next to it with the tap symbol is the supply,

so it will only do s/steel and steel. it says ac dc on the front though??

It's possible that this unit could operate on AC or DC, after all, it does say so on the front panel, and several manufacturers do produce ACDC addon units. The fact that the input terminals are marked Pos and Neg doesn't necessarily mean that it is DC only, the markings would be important for DC operation but irrelevant if it were connected to an AC supply. The question is whether the unit is capable of producing only short bursts of HF for starting an arc in DC tig, or continuous HF for AC tig. Really you need to source some paperwork for the unit to be certain.

Edit: You may get some info from Interlas: http://www.interlas.nl/

Just noticed your earlier post Phase, sorry but Viper is not for sale.
