The first tig i bought was the CIG inverter type which just happens come with a lift tig kit. It is a bit harder to learn on, but my lame mate used it for a lot of the repairs on the bushbaby airframe which worked just fine. not overly expensive and light as onetrack stated. You can now "buy" smaller argon bottles with no lease payments each year and a good bobbin regulator is a great investment.Sorry to tell you this, OME, but that welder you've pictured is obsolete technology, and I wouldn't even pay $88 for one. Inverter technology has superseded Transformer technology, and the advantages are;
1. Much lighter weight (7kgs as against about 40kgs). No more back-breaking work, lugging a welder into position.
2. Lower power draw (saves $$$'s).
3. A finer level of control over actual welding amperage (better welds in difficult conditions and materials).
4. A better and more stable arc, leading to a better weld quality.
I bought a Chinese (Rossi) 200A inverter welder off eBay about 5 or 6 years ago. One of these units (link below). I think I paid about $100 for it.
I formerly owned a 140A CIG transformer welder, which provided good service from about 1985, until it died about 2013. The CIG welder was one of the first to have a PCB in it, and when the PCB fried, I found you could no longer buy it as a part.
So, I invested in the Rossi - making sure it used genuine Toshiba MOSFETS in its construction (the secret to reliability). I have done a lot of welding with that little Rossi, and it is, in a 2-word description, a "little pearler".
It has never failed to work, welds amazingly well, even on heavy thickness steel, and it works in dusty conditions, hot conditions, and generally cops a fair bit of abuse, and it has never faltered.
I would never go back to a transformer welder, they are like stepping back into a Sopwith Pup, after flying around in your Cessna.
