So I bought a harbor freight tig welder (pics inside)
Here are some quick pics i took; keep in mind while looking at them i have ZERO tig experience and pretty much just picked up and ran with this after reading only a few articles on the net and it a few books. The uglyness is mostly the weldor not the welder. Cleaning and preperation of the metal was minimal at best; i mostly used just a wire brush; and on the mild steel in the last pic i didnt even bother knocking off the aluminum coating; with more practice and real prep i know this little welder will perform.
Overall i'm quite impressed with this little machine; we nicknamed it the "Rescue Toaster" after an episode of sealab 2021. My friend saw it and didnt think it was worth a ---- then i showed him and he used it and named it that :P
It's really not a bad machine; the scratch start is annoying but i've got to the point where i can start the arc with minimal effort and not get the tungsten stuck. It has a built in gas valve so you dont need to worry about opening and closing the valve on the torch and it has a 2 second post flow once you stop the arc.
For $200 i couldn't be happier with it

and if it goes better than I hope then i'll probably buy one of smiley's 200 amp ac/dc welders when he gets some more in.Even if you can't hook up a pedal to the welder you can take it apart and figure out how the pot works controlling amps and build a pedal out of that
Thats what i'd do if it turns out untrue I mean come'on we're hmt ffs

Re: So I bought a harbor freight tig welder (pics inside)
the mitec (smiley just put a smiley tools sticker over the mitec label) tig welder uses high frequency start. it superimposes a high frequency high voltage signal on top of the weld circuit and acts as a pilot arc for the tig; that way you dont have to touch the tungsten to the metal to start the arc.
I haven't ever used a welder w/ it but I imagine its a very handy feature. The scratch start isn't so bad; if you stick the tungsten it'll probably break or erode the tip but if you're careful it won't stick and won't erode the tungsten as much. Scratch start still erodes the tungsten but its not too bad.
I can't complain for a $200 welder
