I mistook this as an explanation for the oxygen leak at the regulator. I see now that you are talking about the popping issue.

Beyond the regulator..no, but it can get into the mixing chamber of the torch and into the hose. Once they get hot, the synthetic material the hoses are made of release enough oxidizer to support flame in the acet hose.

Make sure the cutting tip is tight and not leaking any air around it. Also depending on tip size will determine the pressure setting. Acetylene pressure should be 3/5 psi and oxygen pressure around 20 psi. This is good up to about a three size tip.

Easy fix as mine did the same thing last year.

I ordered this kit and put it in and that fixed it. Make sure you get the right kit and it is easy to put in. The seals just get old and let go and needs replacing.

Pretty sure here is the kit you will need taking the numbers off the front of your regulator as yours is the model 250 as mine is the model 350. The parts are easy to put in.

No, just those three pieces in the kit.

If your LP gauge is blown from the excessive pressure, yes, it will need replacing
