My husband and I share the oxygen and propane tanks and use Y
splitters for my Minor bench burner and his Little Torch. When I am
working on glass the psi is set to 10 for the O2 and 5 for the
propane, and he can work on jewelry with that but when I'm not there
I know he sets both of them lower. If you're only going to use one
at a time you won't have this issue. Feel free to contact me
directly if I can help.
