Many folks do very well with a 5 PSI unit at 5 LPM. The required pressure for best performance will be specified by the torch manufacture along with the needed LPM for both fuel and oxygen. It would be my guess that you do not have sufficient oxygen, but without specifying a torch or your fuel setup it is only a guess.

If you need more oxygen then the use of 2 to 3 five PSI units combined together is one solution. Other folks select a 10 LPM unit to cut done on the number of needed concentrators.

The overall key, is that if more oxygen is needed it is most important to combine concentrators that all have the same PSI static output. All 5 PSI units tied together will work fine or a pair of 10 PSI units. But combining a 5 and 10 PSI unit together will not be efficient.

If you are in a panic and need a quick fix, rent a K tank plus regulator from a local welding gas supply shop and lampwork away.
