Rose bud torch question

Not the total answer, but keep an inch or so long cone of white flame in the center instead of increasing the oxygen until you get individual white cones on each hole. I think the one we used to have wasn't as bad to pop out as the one we have now.

Getting too hot is part of the problem, so 1) Use a more carburizing flame if you can.(slightly cooler flame) 2) Don't get the tip too close to the work as heat is reflected, don't hold at an 90 deg angle to the work 3) Use a larger tip at a lower setting(larger tips have better heat dissapation) 4) Sometimes it seems that more fuel pressure helps, I use at least 10 PSI. 5) Use two torches at a lower setting

When I was in charge of maintaining the welding supplies at an engine manufacture, the issue of popping rosebuds torches came up quite often. Some could make them work, some guys couldn't. Finally I talked to the local Welding Gas supplier, did a little Googling and came up with the facts that where most guys set their oxy-acet torches for 6psi acet and 21psi oxy, this works fine for standard cutting and most, not all brazing applications (for this you can turn down the oxy).
BUT! When you put a rosebud on, you need to turn the Oxygen pressure up! If I had the chart handy, I believe the smallest rosebud requires 35psi oxygen.
Turn it up and try it again, see if it helps. The higher flow will help with cooling the tip which in turn should help with reducing the popping.

Oxygen should be set at 5 times the pressure of the actelene, I run 7 psi actelene, to 35 psi oxygen. I get the popping when it gets too hot, with the tip too close to what I am heating. Usually back away a little and don't have the problem.

Not all rosebuds are created equal. Dig up the manufacturers literature on the torch tip you have. Use the manufacturers recommended gas pressures for the tip size for best results.

The general rule of thumb of O2 5X Acetylene will get close for most of the common tips.

yes bottle size on act does make a difference the bottle is filled with white acetone powder act is put in bottle in gas form and is absorbed by the acetone takes about 24 hrs to fill bottle and bottle is filled under water to keep the bottle cool so the acetone can only release it so fast if your rose bud pulls to fast you can actually suck the acetone up into your torch acteylene is the most unstable gas thier is very explosive keep it safe never try to transfer it to another bottle

I have two rosebud tips,one has bigger gas holes and one has smaller holes, one pops, one does not, with the same regulator settings,,,

I agree with the previous posts, mainly, too hot, too close and incorrect/insufficient pressures... From my experience, if you get too close and tap the tip to what you are heating, it pops,,,,,,, sometimes a series of pops, sometimes it stops when you back away, sometimes not...But I know that it sure makes me jump!!!! I try to hold my ground and not be startled, but every time it gets me!!! Dave P

It is usually a good idea to have backflow preventers( check valves) installed on between the end of the hose and the torch. They should be used with any oxyacetylene equipment to prevent those pops and backfires from starting a fire in the hoses. Even with a cutting torch, if she pops and then makes a strange whistling sound, shut it down as fast as you can, because the inside of the torch body is burning. Very bad!! Like everyone above has said, getting the tip too hot will cause this with the rosebud, and while using a cutting torch on dirty or rusty metal, you can get pops when the rust scabs jump off the material you're cutting and hit the end of the torch. Good reason to clean the metal with a grinder before cutting. You'll get a much better job faster and safer.
