Looking again, there is probably space between the water barrel and the
acetylene tank for an oxy tank. Otherwise, I'd guess that the rig is
portable and he stores the acetylene vertical so he doesn't need to wait
an hour for the liquid to settle before use. I'd also guess he can
carry empty oxy tanks any way he wants to.

It is a good possibility that the orange tank standing up
holds propane. It is a lot cheaper to use with oxygen for
cutting only. The little 20 lb propane tank maybe for when
the big tank runs out and you need to do a bit more.

They probably use gas for cutting only and there wouldn't be
any need for acetylene.

Something more to ponder...
