Your propane tanks have an expiration code on them, and they will not be filled if they are past that date. I can't remember how to read the coding or what it looks like, but you may be able to google it.
Oxygen is a big beef for a lot of people. I use concentrators, and only do small beads, so I have no experience. I will say that here in town everybody has better luck with the smaller local welding shops over the big gas supply houses like Airgas, Praxair and Holston Gas.
