if you have not tried alum before stick with the thicker stuff, like I said.  Starting with .050 with leave you frustrated.  Alum dissipates the heat like you wouldn't believe, and some times you just can't back off the pedal fast enough to prevent a hole.  with thinner material it only gets worse.  Just my opinion though.  My welder pretty much stays at 150amps, but I never use all the pedal.  I'd bet I'm actually running around 60-80 amps when my helmet is down.
I set mine at  125 and just mash the pedal for tubing, although I feather it if I have a bigger gap to fill....

I thought it was pretty obvious what I meant, but since not, I set my machine at 125 amps for 120 wall tube...

And you just mash the pedal all the way down and weld .120 wall at 125 amps??????? Seriously? You are saying that you are using the full 125 amps right?

I am far from perfect at tig welding, but here are some I did a while back by "mashing" the pedal, As I said before, I feather for some bigger gaps, but majority of the weld is done at a solid 125 amps and I have always been very happy with the results...

whatever. 125 is a lot of amps for what you're doing.

What diameter tungsten you using? 1/16"? Only way I can see it taking 125 amps is if the tungsten is undersize for the thickness metal you're welding and to me it looks like that is the case. It WOULD take more amps to get the same heat transfer as a larger tungsten. I use 3/32 on tube and nearly everything I do now.When doing aluminum head repair I used 1/8".
