Why does my oxyacetylene cutting torch pop and go out?
The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage. In short, it could be a number of things. Let’s work through the possibilities and figure out how to fix your problem.
Why is my acetylene torch so hot?
A bad oring on the mixer cone where it screws onto the torch handle will allow oxygen and acetylene to combine to soon in the lower part of the mixer, upper part of the handle. A reaction must be taking place there, so it is partially combusting inside the torch and that is why it gets hot.
Why is my torch making a popping noise?
This one is a bit more of a problem. The flame is staying inside your torch for a bit longer, which could eventually escalate to more major problems. Instead of just a loud pop, you’ll hear a pop followed by a hissing or whistling noise as the flame burns inside your torch.
How do I stop my torch from popping?

What are 3 of the most common problems that happen when oxy acetylene welding?
Eye injuries, such as discomfort and burns from the intense light and heat emitted from the operation, and cataracts caused by radiation from molten metal, leading to inability to see things clearly, or corneal ulcer and conjunctivitis from foreign particles e.g. slag and cutting sparks.
What do you turn on first oxygen or acetylene?

Hold the striker against the tip of the torch with the lighter Cup between the torch.
What causes a rosebud torch to pop?
If the velocity of gas flow outward through the tip is slower than the rate of burn of the gas, the flame will attempt to burn inside the tip. As the tip heats, more inner tip ignition of gases will occur. This will produce a banging or popping sound, and can lead to a flashback.
What pressure should oxygen and acetylene be set at for cutting?
Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 ½” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.
How can you tell if acetylene is leaking?
Acetylene Cylinders If leakage is suspected, brush or spray the suspected leakage area with soapy water or with a leak detection solution. Bubbles of escaping acetylene through the soap film will indicate a leak.
How do you clean an acetylene torch tip?

Which of the following is a possible cause if you hear a pop when turning a torch off?
If you hear a pop or a snap, that means you have a leaking oxygen valve, but a small flame at the tip would mean it is a fuel gas leak. To completely shut down, close both cylinder valves, and then release the pressure inside the system by opening the oxygen valve on your torch until the pressure slowly eases.

What should acetylene pressure be?
A full acetylene cylinder which has a pressure of 250 psi at 700F (1725 kPa at 20 C) will have a pressure of 315 psi at 900F (2175 kPa at 310C) and a pressure of 190 psi at 500 F (1300 kPa at 90C).
What is the oxygen pressure set at when using a Rosebud?
First, Kevin says, check the book that came with the torches for the settings for the #8 rosebud. The setting should be 20 – 30 PSI (pounds per square inch) for oxygen. Make sure you read the correct dial, as there are two scales on the dial.

Why does my welding torch pop?
The most common reason a welding torch would pop is from a dirty tip. To fix this, shut off both the oxygen and acetylene, remove the tip, give it a good cleaning, then put it back on. The other reasons for popping in a welding torch are caused by backfiring and not having a neutral flame. To figure out why your welding torch is popping, you first ...
Why does my weld pop?
Popping can occur if you don’t have the correct amount of oxygen or acetylene flowing through the torch. Your weld also won’t look right either. To fix this problem, first, learn how your flame should look. Your flame should be blue, and the shape should be a perfect cone. Also, note the sound it makes.
Why does my gas valve make a popping sound?
You’ll figure this out quickly when you take off the tip to clean it. The reason a loose tip can cause popping sounds is that some of the gases are escaping en route to the flame. To fix this first turn off the valves and unscrew the tip and take it off.
How to fix a dirty tip?
To fix this, it’s relatively straightforward and simple. Turn off both valves (remember starting with the acetylene) then unscrew the tip.
How to get a neutral flame going?
You do not want to have feathers on the end. To get a neutral flame going, turn on the acetylene. (Note that you should always turn acetylene on first and turn it off first.) Then light your torch.
Why does a gas grill pop when dirty?
The reason they pop when they are dirty is because the junk that has accumulated in the tip is not allowing the gas to flow through the tip. Inside it’s letting a little bit out at a time, causing the flame to pop and flicker. A dirty tip can be very frustrating, mostly because it’s not something you’d usually check first.
How to know if a backfire is happening?
You’ll know if it’s a backfire that’s happening because of the noise it makes. When the flame gets sucked back up into the torch, it continues to burn, causing a hissing or sizzling sound. You’ll want to shut off both valves when you hear this noise, then clean out the lines.
Why does my mixer get hot?
A bad oring on the mixer cone where it screws onto the torch handle will allow oxygen and acetylene to combine to soon in the lower part of the mixer, upper part of the handle. A reaction must be taking place there, so it is partially combusting inside the torch and that is why it gets hot.
What happens if the tip set is bad?
if the seat where the tip sets is bad it will do that you will have to take the head to a shop to have a new seat cut in it. if it made in china throw it away before you lose some fingers are the tip seats are bad
Does a torch run cool?
Torch is running stable and cool on the large tip. I notice if the pressure is too low, it starts to heat up like combusting in torch handle, then as it ran up the oxygen regulator psi, it started to cool down. The valve stem end balls are worn rusted.
