ELMAG is just chinese badge engineering. (Which in its own right isn't a bad thing, but you can get the same machine for a lot less...)

My Stahlwerk is a bit dated by now, but was dead cheap with around 1000 Euros, back then. Stay away from the Fronius stuff unless your wife has made a recent inheritance. (With the specs outlined below, you'll be somewhere close to a five digit figure with a Fronius. Nice machines and all, but not that nice.)

For myself I was eyeballing the APEX 200 series, which is China-stuff but with some nice waveform-modulation for ally welding. Stamos does some nice ones too and apparently they are quality checked in Germany, so can't be all bad. Trying to recall the name of the welder I used when welding some stuff for Expo in Milan a few years back, because that was really, really awesome and only like 3 or 4 grand. 

Because you asked for what to look for: no less than 200Amps max current, 250 would be better. As you want to weld fuel tanks, the higher pulse-frequency it can do, the easier it gets to weld super thin stuff. A footpedal isn't a must, but eventually you'll want one, so it better be a standard 7-pin-setup. Make sure you can turn the amperage down to less than stupid low, i.e. somewhere around 5 Amps. And definitely don't buy a completely new model/series unless your dealer is directly in Vienna and will do some sort of pickup service or the like. (Which is why I went with my Stahlwerk, as the same kind of machine has been around for at least the last five to six years.)

Hope this gives you some kind of idea.

I´m a lucky guy.

My wife will buy me a brand new TIG I just need to pick a model that will suit my need.  8)

Thanks!

You should check out migatronic or parweld, nice good quality budget machines. Miller or lincoln electric aren't commonly sold in the europe and spare parts are a problem. Not bad machines, they just dont work well in the european infrastructure.

Yes, surprisingly great machines! Been running mine professionally all year round for heavy 12 hour welding shifts, never serviced it, been running for 5-6 years.
Now it needs a cleaning and calibration, still works fine.

Just to throw a spanner into the discussion, so to speak! :D

Has anyone used one of the Dillion/ Henrob/ Cobra oxy acetylene welding torches. A bloke gave me one a few years ago, as he said he could not get it to work! If you look at the videos on Youtube it can weld any type of metal very easily!!!! Has anyone tried it, or know if it is worth the effort? Supposed to be very capable (in the right hands) on welding thin panels like fuel tanks.
In the past we had to pay monthly rental on the gas bottles in Australia. The market has now changed and we can easily get non-rental gas bottles which makes the oxy/acetylene options more cost effective than a new tig.

Genuine gas welding is quite the step up form TIG, I had to do it in school a few times and I admit I can see the appeal, but I had a really hard time learning it. (But that probably also partly was down to the instructor, as in retrospect he obviously wasn't too skilled with the Oxy set himself...)

Thats a very weird looking gun that henrob. Doesnt look very wieldy to me but i dont see why you couldnt weld thin plate with it as well as any other setup.. i prefer an x11 handle with a small bendable copper nozzle for thin work. Just learned the oxy/acetylene setup these last years, excellent method for gas tanks.

Looks like I should invest some time and learn how to oxy weld. The Dillion runs on only 4psi for both the oxy and acetylene, just hope the regulators can be reliable at such low pressure.
Given my current lack of welding skill, I will be getting my mate to tig weld up the headers on the XS896.

It's similar to a jeweler's torch. I've used them a bunch when I was in school.  They're quite capable.  I see them pop up on eBay for a decent price under retail now and again, but I never get them before they're gone.  They're absolutely worth a purchase, especially with the additional prospect of brazing.
