I have one of the 200 AC/DC Stealth Tig's. The manual is rubbish as said but it's not a bad bit of kit once you (self)learn how to set it up. The supplied torch is the usual WP 26 so a bit ott for most jobs you are likely to do with it.
I bought mine from Weldequip, no complaints.

It's a 26 as that is the only size suitable (gas cooled) for utilising the machines capability (200 amps). Stepping down is nice regarding less cumbersome size but then your limiting yourself on current/material thickness. Especially on ac as that process is much more agressive on torches.
Anyone help me with some beginers info?
I bought a Stealth Digi-TIG 200 AC/DC Pulse PFC MV Welder from WSD about 18 month ago and have just managed to get power to my shed and finish a bench to weld on.
Im having dificulty setting it up (the manual is useless). Im trying to practice on some 2mm steel but as soon as I get an arc the tungsten (1.6mm) just melts. The argon is flowing and the amps are set at 27 the torch is neg.
I'm not sure what the setting on the panel do or if they are set correctly. Any help is most appreciated

wel at first glance you are in ac sine wave (bottom left) you want dc for steel (far bottom option)
that disables all the ac controls so should work fine. assuming you have the torch and earth in the right ports (not reversed) it should be good to go. do check you have proper gas flow though, i had this issue when i thought i had good flow but i didnt.

I got an AC/DC TIG set - I could live without the AC function.
To be honest I got two TIG sets one DC and the above mentioned. I really talked myself into a AC/DC set and like lots of people I have never used the extra function. Mine is getting abit long in the tooth now = Lincoln V205T
What you've never welded ali?

Not a lot. Most of the stuff I TIG is either steel or DC TIG brazing.
I am a motor mechanic - I often get alloy wheels offered to me - bodge up cracks - but I won't do them (as I don't think it is safe).
I never really make/fabricate new stuff - mine is all repair welding - bodging and bolt extraction.
Cheers qwakers
A case of not seeing the wood for the trees. I asked myself which waveform should I use but I knew I was in DC
I'll try again a bit later. Its been 37 years since I last TIG welded so ive a bit of catching up to do.

Probably best since ally 'ages' after welding and the internal structure can radically change. Someone who knows more (or can be bothered to google it) could explain in detail.
Try TIG welding some ally then turning it on the lathe. Usually, the bit you welded is completely different to turn than the parent metal. Even the parent metal changes it's properties where it's welded and is often horribly gummy and tears when you try to machine it.
I was on site once and working close to some ally titan props - large extruded aluminium tubular props like giant acrows they use for holding up formwork. They leave a certain amount in as deadshoring after casting concrete until the 28-day strength is achieved. Some needed to be removed so I could carry on my work so after getting the OK I loosened them off and pushed them over (coz they were 4-5m tall and I didn't fancy handling them by myself. The guy went nuts, he said if you do that the ends get knocked off and you can't repair them, apparently they have to have the ends welded on within so many hours of being cast/extruded so all of the assembly ages together. If you knock the end off, they can't be welded and be sure to achieve their working load rating so he said.
