The amount of oxygen needed for correct flame chemistry is dependent on your torch selection plus a number of other factors. What torch are you using?

Portable units IMO are not suitable for lampworking. They are not built for 24 x 7 use. Only consider a unit that is like the one suggested by Moira. Again, depending on your torch and settings more than one 5 LPM at 5 PSI unit may be required. When combining units it is important that all units have the same static output pressure. i.e. two or more 5 PSI units work well together. While one 5 PSI plus one 9 PSI not so well.

Prices for used 5 LPM at 5 PSI floor units in the USA are in the range of $225 USD. Sometimes less costly depending on source. Also keep in mind the number of hours in use. A low number is much better than high a number. i.e. 5000 vs 25,000
