Just now seen this thread, and read the entire thing. Tons of great info, and links. Lots of very nice welding also.

I.E., a butt weld joint - of two .125" square tubes - should be welded at 250 amps.
Dude! Couldn't be further from correct.... So I don't know what your post is trying to say because I must have missed something there.

I believe what he means; is that when you place two square tubes side by side, the corners are thicker than the flats. Where as, if you but the tubes together end to end, then the thickness would be as listed.

Could not agree more! I have a Miller Syncrowave 250, a Millermatic 200, and a 110v Lincoln mig (don't remember model, it's at my brother's house). 9 times out of 10 I will TIG before I MIG. I know both of my Millers are older, but I bought the TIG over 12 yrs ago, and got a steal on the Millermatic. I will post some pics of some of my welds tomorrow (not on computer now.
