I use oxy occasionally on my EGL S21N (3 tips) and my BMT-7 (2 tips). I
have a separate needle valve/tee arangement that injects it into the
air-stream just before entering the mixer. Got this from some book along
time ago and has worked well for me.
What I really like about oxy is the the flame is considerably hotter, but
at the same time more precise and controllable. I can have my fingers
much closer to the flame without burning. There is also less noise -
alot less noise. I'm trying not to get spoiled by it. Mabey some day
I'll find one of those oxy generators used:) Anyone have some idea what
they go for?
Never tried oxy in the ribbon burner - been sort of scared to. Seems like
an awfully big chamber in there filling up with oxy and gas.
