Or is it just a matter of being patient and working it longer?
Any advice would be welcome.
A couple questions:
(with possible answers)
What LPM are you setting the concentrator to ?
(if you are running at 8 LPM your Oxygen purity is low,
Reduce the LPM setting to 6.5-7 LPM for increased
Do you run with the torch oxygen valve all the way open ?
(If you run all the way open there is not a lot of pressure,
turn your torch Oxygen valve down so the line pressure is a
little bit higher and reduce propane accordingly)
