I guess it would look something like this -
Oxycon --> backflow resistor --> O2 tank --> Oxygen regulator --> Torch

No. A very good concept but here's the challenge. To get all the cubic foot of oxygen into the tank (about 270 cubic foot) it's pumped into the tank under pressure -- thus referred to as compressed gas. In fact, standard oxygen tank is very compressed gas... with a tank pressure of 2100 psig.

Unfortunately, oxycons only pump oxygen at 5 psig to 10 psig. Some of the larger models, referred to as oxygen generators, can pump out 20 psig. Still not quite enough to put much more than about 5 cubic foot in the tank before it just can't pump any more.

There are some oxycons with a 'air tank' attached where you can store a little reserve oxygen for short quick boosts... but not for running very long.

Good logic though
