Thanks for the input, Don.

Well, I love bells, whistles, lights, knobs, switches, etc.

I GUESS neither of these machines are squarewave. I don't even know if I
would want squarewave never having drawn a tig arc or seen anyone do it.

I hope that I can find a how-to video on tig so that I can have some idea of
what I may be doing.

Are all tig torches (water-cooled) pretty much alike? I may can get a
Profax unit cheaply.

What would you recommend as far as consumables, etc?

My only experience is with the Weldcraft WP-20, which I have found to
be completely satisfactory. I have no experience with Profax but
the model 20 looks very similar -- nearly identical.

Only consumables I know of are tungstens and filler rod -- and stuff
to practice on. I suppose collets, cups etc are consumables but they
are torch-specific.

I get my tungstens from:

They also offer CD's and videotapes on TIG (GTAW) welding. I've not
reviewed them.

I think you should quit shopping and start welding!
