I got a torch set from Craigslist for pretty cheap money. It came with
a cart and a bottle of gas. The guy is real sure it's O2, but the
label had CO2 and Argon, with the percentages faded totally away. And
the fitting is not the "normal" O2 fitting, but seems to match that of
CO2 bottles.
The gas itself has no smell at all. And I held a lit match in front
while I just let a little gas squirt out. I would have expected O2 to
have fired that match right up, but it just put it out.
I was hoping it was O2, as that would have saved me from buying a
bottle. But even without it, the cart, regulators, hose, torch, and
tools is worth what I paid.
So is there any way to tell what's in there? I'd like to sell it, but
I think "mystery gas" wouldn't get a lot of takers.

Well your right, a smouldering piece of wood should flare up in O2 but since it
was put out it means a none combustible gas, probably CO2 or one of the inert
gases like Argon.
Most probable that what is on the label is inside the bottle

Have a look at
http://www.concoa.com/index.php?pagetype=showRef&id=11&ref=10&cga=580
if that isn't the one poke around there - you'll figure it out.
You can swap your cylinder straight over for an oxygen one if that's
what you're worried about.

With the cylinder cap off, look on the side of the brass valve for the
CGA number. If it says CGA 580, that is an inert gas cylinder, and thats
why there's a lable that says Argon/CO2.

Mine is 7/8", so it looks like it's either CGA-034 or -035. That would
make it inert gas or industrial air, if it follows that description.
But, you're right, I only really care if it's oxygen, and I didn't
know I could just swap it. Solves my problem, thanks.
