Jack; it's a Lincoln 175 square wave. Works real good. I use a air cooled LA9 Mag torch. "comes with the machine" It will do a super job on aluminum or stainless also. Just have to learn how to use it.

It's harder welding around tube.
How about straight & level does it get better?

Your doing a lot better then guys that I work with,and being able to TIG weld is in the job description.

What is the wall thickness on this tube? What diameter of tungsten and filler rod are you using?

On small diameter round tube I weld about a 1/4" to 1/2" (depending on the diameter), and then reposition the tube.

The hardest thing to remember to do is to rotate your wrist as you travel so that you keep the tungsten at the proper angle to the surface of the tube.

I'm a novice at this.

Is a lazy susie table used to rotate the piece while holding the torch still? I guess that would only work for Mig, Tig sounds like it keeps both your hands too busy to use a rotating table.

They make a motorized rotating device that has a foot pedal. We have them at work that have a drill chuck on them and special plates that clamp into them to weld tubes of all sorts and configurations. The McMasterCarr website has a few of different sizes. They are used for SMAW, GTAW, AND GMAW.

Dan, the tubing is around 3/32" wall thickness. Using 1/16" tungsten and ER70S-6 rod. I was concerned more about strength than pretty. I'm sure it's strong enough but it sure wasn't pretty.
