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

it's the same.

Ummm..... no, it's not. Read the other responses in this thread from people
who actually know the difference.

i read the responses. It's the same.

It *can* be the same. However, oxygen graded for welding, but not
for medical use, isn't safe for medical use.

Wether or not a store sells medical grade oxygen to welders is up
to the store and not universally true.
