Perhaps, but probably not the accurate one. The reality is that the
purity standard for welding O2 is tighter than that for medical O2.
Ultimately, except for the "analytical grade" all of them come from the
exact same cryo tank of O2 at the filling station.
A friend uses "welding oxygen" to fill his breathing tanks for high
altitude flying in his Harmon Rocket.


Hope he doesn't catch fire and explode.
My guess, he'll be fine.
