The rosebud won't light. Acetylene/O2 burns twice the rate of propane, and you can't get the propane/oxygen out of the rosebud tip fast enough for it to stay lit.
You can light the rosebud with propane, no oxygen - but as soon as you turn on the oxygen, it will blow out the flame.
You're not going to get the pressure up high enough so it's useless with propane.
I don't use a propane torch to heat anything excpt glass
That is not correct, If I am reading your response right. if not, then i apologize. When I use my rosebud on my oxy/propane, my O2 is on about 10psi, and propane at about 3-5psi. I light it the same as I always do. once lit, you have to turn the fuel down until it barely kisses the tip. then add Ox, then more gas, then Ox again until the little cones are close to 1/2" long. I regularly heat 5/8" rod to bend. it takes about 20 seconds to get cherry red. I use this setup nearly everyday in my shop. works very well.
