Helium is kind of spend these days. I bet this magic mix is even more expensive. Here's some info I've found interesting from Jody and his dad gum good videos on the subject, watch them both if you have time--near the end of the first video is a link to the second video on the top right hand corner of the video window:
Video shows Tips for Tig Welding Aluminum using argon and helium mix
I bring this up mainly because its a good video on this, but also because there is some contradictory information in the powerpoint. On pages 11 & 12 of the ppt, they tell us that with helium and argon mixed, there is considerable difference in the width of the weld bead but no significant difference in penetration. In the second of Jody's videos you'll see a significant difference in penetration when he cross sections the weld and etches it. Plus I wonder how width and penetration differ between filler metals and base metal compositions.
Not saying that is the case here... but the industry has made gas mixture and selection a very confusing proposition in the past...
they juggle the gas proportions slightly ...then...give them magical sounding names... and they have the latest miracle to arm the sales staff..
If you want to see how muddy that water is... here is a gas mix cross reference that you might find interesting

When I see mixtures in the "parts per million" range, I think contamination more than some mix with a purpose. Is the discussion seriously about "parts per million?" That's almost down to counting the molecules of oxygen and nitrous oxide to be found in your tank of the stuff.
I see an opportunity here to invent a whole line of "ppm" mixes of gases, none of which can be told from the other.
