Hello everyone, I'm new here. I'm looking at one old German AC/DC TIG and I want your guy's opinion should I buy it. I have done some research on this but ist really hard to find any info on at least 20yr old machine. I have heard of Merkle before but I haven't used any, what I was able to find is that there are at least 4 different versions of this machine with the same name INSQUARE 250W(photos below). The one I'm looking at costs around 550$ and seems to be the fully-featured one since it has all the potentiometers in contrast to others that have some of them missing(BDW. guy selling it has no clue about it). Can someone recognize that connector used in the front of the machine that really looks like a MIG connector, thankfully the guy selling it has all the cables so its less of a
problem. Also it seems to have a water cooling system too which is good for the price.
This is the one I want to buy:
Connector I have never seen before on a TIG:
These are others that I was able to find in my research:
