Can you run a National 3A on a conentrator? How big?

How big a flame do you want?

Well, right now I'm using an OX-3 or OX-5 tip and making marbles up to about 1" - 1.25", and making pendants.

I'm wondering how much concentrator it would take to do this kind of work. Right now I'm working on bottled O2, and I'm thinking that's going to be a pain dragging them in and out when winter hits here in Wisconsin.

Any advice would be appreciated.

Thanks,
Kelly

The OX-3 uses up to 12 CFH (5.6 lpm) of Oxygen
The OX-5 uses up to 20 CFH (9.4 lpm) of Oxygen
