it’s dense, it might be. haven’t used it for anything other than an inert environment. it’s more expensive than N2, so I only use it where I need it (welding and making d8 these days 
)

You should never use anything to push that you don’t know the pressure chart for. Always research before trials. If you weren’t able to keep it as cold as you did it would have over pressured your system.

Its definitely taking longer to recover…I vent to zero this tims.its staying there but not boiling in the pot as much as usual…fun experiment got the job done…almost done recovering only 1more run
it was posted upthread…

This is incorrect information there are alot more differences than weight. This should have never been recommended and Noone should ever do this again
I have one these laying beside me w my new welder a argon regulaotor… only goes to 60psi correct wonder if I should be using it , I won’t go over 40psi this time
He did not look at it till after he was done and got lucky

why exactly?

With a boiling point of -185 it is incredibly hard to control.
The chart just says to get it to 0psi takes colder temp
If its heavier it going to the bottom I guess having to pure through the tanw maybe
and the boing point of helium?!? (-267C)
or nitrogen? (-195C)
(both of which are lower than that of argon… -185C)
he wasn’t pushing with liquid, so how is the boiling point the relevant physiochemical metric to base “it’s dangerous” on?!?

Hell what u talking about to start run 2…I’m venting and have prvs and gouges at every stop,well.except the lines
Bingo smart way what i was trying to say i don’t need it liquid thus i don’t need it that cold -120 or whatever
Heliums pressure doesn’t fluctuate as much as argon will.
I’ve been drinking a bit and am probably not explaining it correctly.

come back anytime…I’m always here
and if you’re correct, I want to understand why…
@TurahTurah seems like she might grok physical chemistry well enough to tell us we’re both wrong…

We’re using in gas form. It’s inert under our conditions. Stop drinking, it makes you dumb

I’m reading this thread now. I have never worked with helium personally in the lab, and I can’t say that I’ve even seen it used in industrial chemistry.
I’m just waking up so let me catch up

What about argon bc thats the main question
