Is there any difference between a tank of welding oxygen vs medical

it's the same.

no it isn't
It is not necessarily the Oxygen that is different but the tank. The
tanks look the same on the outside but are markered different.
Medical oxygen tanks are held to a higher standard than industrial
oxygen. Medical tanks are "Oxygen clean" whereas welding tanks may
not be as clean. Medical oxygen is also dryer to prevent rust in the
tanks.

Bull**** . That medical O2 comes out of the very same tanks as welding O2
. And in some cases welding oxy is held to a higher standard of purity . And
any impurities in the tanks can cause the same problems , no matter the
intended end use .

CHECK THE DATE ON THAT POST , you're responding to stuff from 5 years ago

That's what you get from a google grouper. Still an interesting
question that I have never seen.
