I have add'l pics. Per your recommendations, these changes and verifications have been made: 1. verifies AC aluminum light lit 2. verified 100% argon 3. torch leak: none 4. set balance to 70% 5. amp setting 150 6. flow increased to 20 cfh 7. freq verified at 120 Hz Thanks to all of the helpful respo...

Thanks to all immensely. I will get to work checking the basics and try to get a puddle on a flat sheet with new recommendations: 150 amps, 3/32 filler, 70% Balance, 120Hz and check gas, torch leak, machine setting for polarity, reducing gap between pieces; will go back to basics and report back.

Exceptionally difficult day working TIG aluminum. Dynasty 210 settings made according to many recommendations coming in as follows: 1. Balance set at 60% (this is the lowest setting; it will not go to 50% as recommended) 2. Frequency set to 120 3. Gas flow at 10 CFH 4. Work itself grounded (not the ...

Machine (Miller Dynasty 210) was purchased in 2020 about 6 months ago. I will look at paperwork & research further settings like frequency. Just an aside: I got so frustrated with TIG that when I owned the Diversion 180 in 2017, I shoved it in a corner in the shop and thought I never want to use...

Thanks for all the info. Forgot to mention machine = Miller Dynasty 210 (not the 210 DX). By the way, very expensive new machine. Don't know if this machine allows setting frequency. I got this machine and got rid of a Miller Diversion 180. I had essentially given up on being able to use TIG, but al...

Most difficult to impossible for me is TIG welding aluminum in side a 90 degree angle. No matter how well tungsten is sharpened, the speed of travel, or the cup size (#7), the arc will wander between the vertical and the horizontal sheets of aluminum making it difficult to add filler to a molten non...
