difference between argon and oxygen tanks?

I was wondering if there is a difference between oxygen tanks and argon tanks for welding. If I got an oxygen tank would I be able to get it filled with argon for mig? I found a guy willing to give me an oxygen tank for $40 but I want to use if for argon. If anyone knows could you jsut give me a heads up? Thanks...

Same tanks, different label. I would check with your supplier though, since having Oxygen in the tank previously may contaminate the Argon, since you are trying to displace the oxygen around the weld with Argon.

First is that they purge and vaccum any new tank that is not labeled by the supply house. Secondly, you are usually not getting your bottle back. You just exchange for one of theirs.
