I am very new to Tig welding. I just purchased a Lincoln Square Wave 200. It came defective out of the box, flashed 100 and nothing could be adjusted. Long story short, Lincoln tech had me remove the cover and I found that the retaining clip for the wiring ribbon on the back of the display circuit board was broken and the connector was half way out. I pushed it back in and the display now functions.
So, now I am worried that the unit is a dud. I tried to run a bead on a razor blade with 1/16 tungsten at the lowest possible setting and it just burned through it. None of the welds look clean on the thicker stuff (I am not using any filler, just practicing control and fusion welding). The tungsten gets trashed quickly and the arc wonders all over the place, the pulse function (set at 1) is barely noticeable. There are a lot of sparks when welding steel. When I set the unit to AC welding for some aluminum (120 amps, Freq 120, Balance 75) it just torched the aluminum (see pic) black and pitted.
At this point, since I am so new to Tig welding, I am probably going to return the unit and get another one since it is broken inside anyway (retaining clip is snapped off). However, I am sure some of the above is my fault due to lack of skill, but it just seems to me that if I am welding on 16ga steel that I should be able to get a clean weld going without burning holes in it at 40 amps on the peddle.
Would love to get set in the right direction if anyone has some tips.

Maybe he'd do us a favor by closing this forum.
I mean, in it's crippled form it doesn't effectively serve as an alternative to Welding Web, not that Welding Web is bad, but there are some who would undoubtedly prefer a tamer forum. And as you know, I like to mix it up a bit over there on WeldingWeb, but, ideally, an alternative, without as much bi-polarity will have a good place on the internet too, like how this forum and the members are.
So, maybe killing this forum would give rise to a new, fully-functioning forum somehow.
Otherwise, the Everlast Forum is nice too, since I'm an Everlast users and a fan.

A new poster can get more action at WeldingWeb, and some new posters here and elsewhere may be in such a hurry to solve their problem that they'll post on a few forums until their solution is arrived at (which I don't really blame them), and then may never return to the forums and give the closure to the thread. That's why I thought to do it, because I noticed it resolved at WeldingWeb. I'm sure you've noticed that kind of thing a lot too, George.
But this forum is kind of a crippled one, with no functional photo posting ability. I mean, the Everlast Forum is now working quite well, but there's not much interaction there yet, undoubtedly due to it having problems for so long. And so, WeldingWeb seems to catch most everything welding wise, like flypaper...
