Or 100% helium on DC Tig welding aluminum is a fun option too. Even pumping some helium in with a Y on a spool gun helps as well.

DC and aluminum? That can't end well.  :D

It's just fine, get it good and clean with an etch then SS wire brush then the helium breaks up the oxide layer on the aluminum works great on thick stuff since all the heat goes into the part.

All of the aluminum stick rod I have ever had was dc, could not be used with an ac machine at all. They may make some ac rod, but I never had any, I did try it with an ac machine once though.
Old LT40HD, old log truck, old MM forklift, and several huskies.
