Pelican's Perch #13:Getting High on Welder's Oxygen
Having problems finding Aviator's Breathing Oxygen to refill your bottle? Upset about the rip-off prices some FBOs charge for an O2 fill? Don't put up with it, says AVweb's John Deakin, who explains why it's perfectly safe ? and perfectly legal ? to use cheap welder's oxygen, and tells you exactly what you need to know to buy it in bulk and do your own refills.
Oxygen is oxygen. It is the substance that matters, not the intended purpose. These days, welding, medical, and aviation oxygen are exactly the same. All three come from the same tank of liquid oxygen (LOX). The liquified form is the cleanest, purest, driest form of oxygen (or any substance) you'll find anywhere.
