Oh and also that 4% to 7% drop in purity from tanked to oxygen concentrator will be noticeable on a bigger flame so hunt for a 10L unit if you can find one or a couple of 5L together {which equals just about 8.5L usually}.
That is if you are going to be doing the bigger flame.
I have GTT Cricket on household natural gas ( a lot less burning umph than propane ) and a 10L I got lucky to find cheap here in 'Merica.
But I only do hobby stuff and nothing of any size so a big flame isn't needed to satisfy my molten glass addiction.
