Using an oxygen concentrator with oxy propane questions

[Mad Matt]

Ok so looking around I can find an oxygen concentrator for the price of an oxygen bottle. But then I don't have to fill it. So an oxygen concentrator seems better. But the question is how can I set up an oxygen concentrator instead of an oxygen tank to run an oxy propane torch and oxygen concentrators seem to be listed in litres per minute. How many litres per minute will I need to run an oxy propane rosebud?

It depends on the torch and rose bud there may be some data from the manufacture but this should help.
L/min=0.035 CF/min concentrators operate usually around 5/7PSI
The local welding shop may be able to help, you will likely need barbed adapter fittings and such.
Concentrator can be set up with a Y or T fittings if you need more O2.
