Torches

[Anonymous Poster]

Question for all you rod burners and metal melters out there. I needed to remove some rusted bolts today and decided to use the rosebud to apply some heat to help in the removal. After 1 or 2 minutes of use I noticed that the point where the rosebud attaches to the torch body was very <font color=red> HOT. </font color=red> (About the only thing hotter would be my wife if she ever found out I used the coffee grinder to munch up some chicken pellets to make a mash.) Any ideas what would cause this??

Russ, I'm probably not enough of a welder to know without seeing that torch in action, but I'd wonder if the tip was loose, i.e., not screwed on solid and most of all I'd wonder if you failed to give it enough oxygen to keep the heat blown out the end.

As Bird said make sure you are giving the tip enough oxygen and then some. The rosebud has alot of heat close up if you don't run enough oxygen the tip will get very very hot and then one of two things will happen. You will either blow the tip out--melt it-- or have a back burn not good sounds like a jet taking off its the gas burning up the inside of the hose.---be careful---

Russ,
Check all connections and look at your "o"rings,also have your torches been rebuilt?
What setting do you use on the the gauges..double check,also if you have flash backs for the could need replacing.
Be careful. /w3tcompact/icons/wink.gif
Take care and stay /w3tcompact/icons/cool.gif

As my oldest Brother would say, if you have a flashback or backburn (however you wish to term it) all you would see of me would be (cleaned up version) rearend and elbows hoofin' over the closest hill! Be extremely cautious my friend! We don't want to miss your posts on the board!

Something to check for on your torches is burnback preventers on the lines if not already built into the torchhead. What they amount to is checkvalves let the gas out but don't let the flame burnback up the gas lines. Mine are mounted inline at the end of my hoses attached to my torchhead.

Gordon, as we've all learned in various ways, it is good to trust to 'technology' only so far. Prevention is the name of the game, and knowledge is the basis of prevention. The end result is a strong dose of awareness which results in the keyword....Safety! At least in my oddball way of looking at things. In my work, I prefer to error on the side of caution.

I use a rosebud to heat large areas. Usually just use a decent size tip to heat bolts red hot (or a cutting torch to cut the head or nut off). Torch tips work in a pretty hot environment and a rose bud generates a ton of heat. The gas flow keeps the tip from getting too hot if adjusted properly.

Thanks to all you guys that responsed to my post. Not only did I get an answer to my problem, I got a valuable education. Like Scruffy said, knowledge is the key. The problem was the pressure setting on the regulators. Like you guys mentioned, a rosedbud generates a tremendous amount of heat and you need to have the correct pressure to keep the heat flowing. In addition, for what I was trying to do the rosebud was overkill. Thanks again for all your help!!
