prestolite air-acetylene torch

Jewelry | Welding

I am returning to silversmithing after 20 years. I have a B tank acetylene torch with prestolite torches. I use air rather than oxygen so I have only one tank. When I light my torch (0, I believe) it has a pretty little blue flame but goes out most the time when the hose is moved. I've cleaned the tip and tried to adjust the air but I'm not sure what else to do. Does any one have any suggestions? How are the tips put on to allow enough air I have tried to locate instruction of the tank and torch tips but haven't found much other than turning it on. Any help will be appreciated.
Thank you,
CJ

CJ, Prestolite torches draw

CJ,

Prestolite torches draw in atmospheric air from the front, right at the point where the tip screws into the handle. If the torch has sat idle for years, the air inlets could be clogged with dust, dirt, soot or insect nests. Take the tip out, remove the hose, and blow the torch body thorough from both ends with compressed air. If you don't have an air compressor, get one of those cans of air they sell to clean computers.

If that doesn't do it, you may have a problem with your regulator not supplying sufficient gas. In that case, you need to take the whole works to your welding supplier and have it checked out by a pro.

Are you using the very tiny

Are you using the very tiny tip? It can be a hard one to light without blowing it out a few times in the process. Try a bigger tip and/or reduce the presure.

Comments

I do appreciate the helpful suggestions on how to solve my torch problem. I'm not so lost when soldering with an iron while building stained glass, both leaded and copperfoil but I'm on a learning curve with a torch. I think my biggest problem is overcoming my fear of them. I just wanted to say thanks for people taking the time to give me some guidance.

Remember that this system

Remember that this system makes a popping noise when it's lit and turned off. It makes a softer flame than torches with oxygen and you are far less likely to burn a hole in anything. Get some scrape metal and a fireproff surface and experiment. Try to melt some of the metal. Solder scrape, it's only metal.
