I thinking about buying a tig welding machine
I would like to have your opinion
Other than steel and inox I would like to have the ability to weld aluminum
As I donít have three face power supply, we are talking about a 220volt single face machine
I wonít use the machine for professional use
My budget is nearly 500 euros and if we are talking about something that worth the money I wonít have any issue to spend 100-200 Euros more.
I have no idea about the specs of these machines (other than amperes and the way the arch starts-with or without touch).
I would like to hear your opinion about what I must be careful of
I have an 200 amperes inverter welder. I have seen at ebay some kits that converts these welders to tig, but I donít know if it worth the money. What do you think?
Does it worth to look for a second hand or it better to go for a new one
What are the low middle and high brands in the tig welding area?
After a quick search I found this from Poland
this from German
and this from China
What do you think?
Any advice is well accepted
Thanks for your time

You thought of maybe getting a MIG instead? It is quicker for most things unless you need it for really fine work where the TIG is needed.
With a spool gun or a PTFE liner you can also do Aluminium without having too much skill or practice.
For fabrication of steel structures it is also much quicker easier than ARC.
I have an R-Tech 160 AC/DC welder and I really rate the high frequency start and pulse functions. They are both a must. I will however buy a MIG very soon for a job.

Just be aware the running costs of TIG are far more expensive compared to MIG. It's not just the buying of the TIG there are hidden costs.
Gas needed for aluminium is Pure Argon or Helium argon Mix for more specialist aluminium welding which costs lot more than typical 5% mix Mig gas and lot more expensive than Co2.
Tig is much more dependant on Gas flow so you need Gas Flow meter not just Regulator showing pressure like most Mig setups use.
Also because off the Slow nature of Tig welding compared to Mig the Gas usage is higher. Mig will cover lot more Mtr's of weld for the same gas usage. And it's cheaper Gas.
Then you have the Torch setup. For best control and weld flow you really need a foot pedal so have full control of amps. Tig torches with switch are ok for awkward places but are limited for fine work because they don't have the same control you have with foot pedal.
Also standard Tig cups are Ok but for better welds you'll soon want to use Gas lense so that's more hidden expense. They do however pay for them selfs long term because you tend to use less gas or should say waste less gas.
So what I'm saying is really look if you need TIG because it's not cheap. Also welding Aluminium with TIG takes a good while to learn and is very unforgiving. Can be very frustrating for first time user because just touch down the Tungston one time and you have to stop and clean/regrind the Tip.
Also If you Eye sight is at all dodgy TIG will soon find out because TIG is much more visual. Good Auto shield helmet designed for TIG is a Must because TIG fires much quicker than Mig and is Lot brighter so the helmet needs to respond faster to the Arc.
My Tig is 200A form R-tech and I love it. But it took me nearly half of Large Bottle of Gas before I got anything like resonable at welding Aluminium and I ground a lot of tungston.!!! . . . I relate TIG to Old Fashioned Gas welding and I was very very good at it in my youth having welded more Cars than Ford so thought TIG would be easy.!! I was Wrong and it was real Eye opener. Thou must Say I do love TIG now but only For Aluminium and Titanium or Stainless for most things in Steel I'll always turn to MIG because it's so much faster.
