I currently use an Extreme Oxygen 15 concentrator and propane for my Nortel minor burner. It works very well but I am limited in what I can do with Boro. I am looking to upgrade to a Nortel major/minor burner to advance my beading and work with Boro and am considering using oxygen cylinders rather than piggy back oxygen concentrators.
I am trying to find out what size oxygen cylinders most of you use and approximately how many hours of beading you all (I live in Tennessee) are able to get out of them? Or any other opinions about cylinders versus concentrators.
