Hi guys,
I need your help in buying a new TIG welder.
I already have a very basic DC plasma-stick-tig welder, but I’d like something with more amps and with AC capabilities, to give aluminum a shot. Searching on ebay I’ve found these three that seem interesting:

http://cgi.ebay.it/IGBT-200Amp-AC-D...40A-cutter-4-in-1-/170523332028?pt=BI_Welders
Actually the first two are very similar, probably the difference will just be in the shipping price and the foot pedal included in the second one…
The third one has got AC frequency regulation and up slope, which the other two don’t have, and post-flow is longer (0-25s vs. 0-10s)but its pulse frequency is lower, only 25Hz compared to 300Hz of the others and it doesn’t have pre-flow time regulation.
I know you are not magicians and you can’t tell if one will broke and the other not but, which one do you think is better “on paper”, just from looking to the specs ?
Basically my question is: do you think that’s is better to have more pulse frequency but no control over AC frequency, as in the first two welders, or is better to have an option to control the AC frequency, at the expense of pulse frequency and pre-flow?
Ah, just for a frame of reference: I perfectly know where these welders come from. I know that Fronius, CEA, Miller, Kemppi, Lincoln is the way to go, but I’m not a professional, and I simply can’t afford them, please understand me.
Thank you very much in advance,
massimo
