This is the gauge I use with a pre-mixed tank, but it will work perfectly well on a pure Helium tank alsoOscar wrote:My question is exactly what regulator are you planning to use on the helium tank?

Correct. There's 2 versions of that gauge, one is PSI the other is CFM. Both support Helium (and I do use the CFM models).Oscar wrote:That gauge is configured for output PSI, not CFM. If using CFM as the sole indicator, wouldn't he need one configured for CFM, so that he may dial in his desired mix percentage?

Ah I see, I was wondering what was a good regulator for Helium. Thanks.
I would venture to say that is incorrect, in general. That might be specific for that Dartmouth RTA thing, but look at this Miller flowmeter. Not that 10CFM of argon (well the ball location that is), is about ~23 CFM of Helium. Now I see why people, including Jody, say you just barely have to crack it open and float the ball above it's seat; it's a heck of a lot of flow, probably due to density differences.rahtreelimbs wrote:Found this thru a Google search. Does this mean that since Argon and Helium are very close in numbers a flowmeter for Argon would work for Helium?

Which gives a 3.19 factor when using an argon flowmeter with 100% helium ( Ar 1.18 / He 0.37 ) which is close to what a welding engineer suggested ( 3 to 3.5 ) we use while waiting for a helium flowmeter.

I had a weak moment and just bought a mixer.
