Not sure about welding o2 but do know all medical oxygen is all totally
dry - the only difference with aviation o2 and medical is the paperwork.
Years ago a friend of mine was CEO of the then CIG and we were worried and
run a test on moisture on medical cyclinder and it easily meet the aviation
std.

Looking to fill small bottle Aviation oxygen in Melbourne does anyone know

Alan,
I was faced with the same problem when I bought a small Aeromedix
portable system because our club ships weren't fitted for oxygen. BOC and
Liqidaire won't fill cylinders that aren't theirs. I came across this
link - http://www.avweb.com/news/columns/182079-1.html - and now fill my
bottle from my welding cylinder. As the article points out, welding oxygen
has the same moisture content as medical breathing oxygen and comes out of
the same tank. Any ice formation is probably coming from unpurged air in
the transfilling line. I've had no problems but have yet to try it over
15000 ft.
Cheers
Graeme
