If this has the small "propane torch sized" oxygen bottle, those don't
last long at all in my experience -- propane and MAPP liquify under
pressure so the bottles hold a fair amount.  Oxygen does not, at least
not under the pressures that a little disposable bottle would contain,
so there really is not a whole lot of gas in there.

I used a kit like that once, it was a long time ago but I seem to recall
the oxygen being gone in just a few minutes.
