I can say that medical O2, welders O2 and aviation O2 all come off the
same tank, so they are exactly the same product. I don't know if the
various tanks or eqp used have any affect on flow/use thou.

Thanks. That's one of the few online sources I did find, but it's
good to have the confirmation that the oxygen is the same thing.


All the best,
