Hello Alfredo, the thread that John included in his response to you had to do with using a cutting attachment on your torch set-up. I believe you are trying to use your torch to braze or weld? If so, popping can come from a few different things. Most welding tips are two piece units, if you have a Victor torch or Victor clone, the mixer for the torch tip is housed in the brass piece that screws onto the torch body, the actual tip is screwed into this mixer piece. If the tip isn't seated tightly into the mixer housing you can have a situation where the torch will pop due to improper sealing, so check to see that this joint is indeed tight. The mixer housing on these types of tips has a twisted copper piece that is inserted into the inner bore of the mixer housing where the seats are located (sometimes as a result of backfires this copper piece can be burned out and cause the tip to lose it's ability to mix the gases and provide a stable flame), check to see that this insert is in good condition. If you're not sure what to look for look at all of your tips and take notice if there are any differences between how these look. The seats on the mixer portion of the torch have O-rings on them and should be inspected to see that they are in good condition and don't have any tears or cuts that could cause a leak, this could also cause the torch to pop out. Also inspect the surfaces where the tip contacts the torch body to see that there aren't any apparent scratches or deformities that could cause a leak.
Now to the simpler side, do you have the correct pressures set on your regulators? Check a tip chart to insure that you are using enough pressure for the particular tip that you are trying to use. Also consider that you could possibly have a bad gauge and the pressures that you have set on the regulator might be incorrect due to damage to the gauge. Finally, if you aren't using a high enough flow setting on the torch you could be starving the tip and causing it to pop-out. If you have enough flow of fuel gas and oxygen passing through the tip you should be able to touch the tip near it's end while it is burning and not feel an excessive amount of heat. If you do feel a lot of heat on the tip the lack of flow is allowing combustion to take place inside of the torch tip and that isn't good so you'll need to increase the amount of fuel gas as well as the oxygen to attain a neutral flame. When the flow is correct there will be minimal heating of the welding tip near it's end where the flame is being produced. If it's too hot to use for your purpose when you have reached this setting then it's time to use a smaller tip. Best regards, aevald
