Aviation Oxygen

[drifter1430]

Just trying to get an "Advanced" discussion started...

I was surprised to find out that it all comes from the same manifold and after years of being told that welding gas was bad or dirty, that "we have been told by the suppliers of welding oxygen, the purity level required for welding and cutting purposes is more critical than for breathing".

I don't have a mix station completely set up yet, but through where I work I can get a discount on all kinds of gas (industrial, medical and aviation, not to mention helium.) After paying roughly $55.00 for a fill of 21/35 in a set of double LP85's at a local shop. It's time to get going.
