Grant -

I don't have a rig, but is it a heat issue - pre-ignition. Maybe an air leak
that the gas that flows sucks in air and ignites poorly.

Just guessing - but maybe an idea. O-rings might do this - if high velocity gas
is flowing past.

I've been keeping my eye on surplus oxygen/acetylene gear locally and
picking it up when it's cheap, with an eye on reselling. I now have 3
cutting torch attachments all of which are high quality and all of which
seem to have the same problem. They pop and go out a lot. I haven't
replaced the tips, but I have cleaned the tips including the seating
tapers until they are really as clean as they'll get, by soaking in
vinegar and salt and gently rubbing with 3M pads. I have also used tip
cleaners to try to gently get as much junk out of the preheat holes as
possible. I don't know of a good method to clean the seats themselves,
though. This is the hole in the actual torch head. It would seem to
require some special tool to clean the seating tapers.

I believe the popping is simply from improper seating of the torch tips.
Is there another common cause?

Any of you guys have a good method for doing this job?

By the way, Seattle is blessed with a great torch repair place, Hansen &
Miller in Ballard, but they are expensive and so are new cutting torch
tips. That's why I'm trying to do this by myself.

These are all real nice torches or will be once they are fixed.
