Can't get stable flame with Oxycon Propane and a little Smith Torch

[Muggins2003]

Thanks a million. I'm getting far better flames now! The only thing that is now happening that didn't use to with the oxygen tank set-up is that if a lot of the time if I move the torch the flame is extinguishing - is that just something that happens with this set-up or is it an indication that something is still slightly off? Sorry for more questions - I'm definitely getting there!

I've been told that the flame isn't quite as hot as on pure O2 - the oxycon is putting out ~93% O2 by comparison - so that may have an impact; however, I can probably conduct 4/4 time with mine without issue. Being careful where it's pointed, of course.
