Before I send this AHP Alpha Tig welder off to the winner of the giveaway, I filmed some more tig beads on aluminum and tried to dial in some sweet spot settings on 1/4" thick aluminum.

I cut several pieces of 1/4" (6.1mm) thick aluminum using the Evo dry cut saw.
I like to use Irish Spring bar soap for lubricant because it smells good...and because it seems to rinse off easily.
After the cutting was done, I used some Aluminum Cleaner and scotch brite to get the pieces nice and clean. (I plan on using these pieces to test advanced settings like wave forms, pulse, frequency, ac balance, and more)
These settings worked pretty well but there was a lot more cleaning action than was needed so I made a few minor adjustments.
These settings seemed to provide better puddle control and the electrode didnt ball up as much due to the lower cleaning setting on ac balance.
The first job I did with the AHP Alpha Tig welder was some carbon steel parts that I could set up on my turntable.
The welder did a good job but the #17 air cooled torch got really hot.
Thats because its a 150 amp torch and I was pushing it on back to back welds at 180 amps.
The settings I used for 1/8" thick aluminum were slightly different from what I liked for the thicker aluminum.
Higher frequency settings seem to work better for me on 1/8" and thinner.
