    Thanx, guys.

    Dirt, rust, and seating. Using knock-off tips bot from Amazon for $6.00. Victor style torch by Forney, bought in 1990. Used a wrench, and the popping stopped! Will try cleaning the plate with a grinder prior to cutting. The book recommended this, too.

    A side benefit from all this cutting is I'll have lots of plates for stick welding practice! Love my local industrial surplus store. 85ยข per pound for scrap steel of definitely unknown composition.

    Lots of structured practice ahead. Wish I had an onsite instructor, but that's a $10K luxury. Didn't have one for MCSE, C, Oracle, or Unix, so I should be able to do this on my own, too. You guys are the next best thing.

    The book is "Welding Level 1 Training Guide" by NCCER. Pro level book. You can tell, because half of it is safety stuff, like having a fire watch, using the plant electrician, etc. Geared for industrial level.

    Amazing what you can learn if you just try.

    A piece of dirt ,rust concrete on the plate will cause this

    Haven't cut with OA in a number of years but can provide a couple of thoughts. Perhaps someone more current has some other ideas, but here's what I would look at. First, a bad seal between the tip and the cutting torch head might cause popping noises. Is the nut that holds the tip tight? Don't tighten it like a lug nut on your truck, but be sure it's firmly tightened with a wrench, and that there is no dirt on the seating surfaces. Second possibility is you don't have the flame adjusted high enough-try adding a little more heat and see if it helps. Too much will ruin your cut quality but you may be on the hairy edge of just barely enough heat. Might also be that your travel speed is a bit too fast, or that you are unconsciously letting up just a bit on the cutting oxygen handle.

    Also, what kind of torch? Imprecise machining at the mechanical interface between the tip and the head could do this. I think I have a vague memory that even a super quality company -I think it may have been Victor -- had this problem 10 years ago or so when they put out some poorly-machined cutting heads. They immediately made it right with their customers, of course. But if your torch is a lower-cost import, that could be the problem. Also, are you using tips made by your torch mfr., or generic tips? Not a place to save a buck-buy tips from the same guys who made the torch. There is also the possibility of overdrawing from a very small acetylene tank but that seems unlikely with a #0 tip. Hope you get this figured out.

    For a long time, I despaired of making good cuts with the torch, then, I read in a training manual about different tips. I now have the right tips. But, now, there's a couple of problems.

    I'll be cutting along, just fine, and, all of a sudden, I get a crater, and a blob of slag, and have to restart the cut. What's wrong? 1/4" steel. #0 tip. 5 lbs acet, and 20 of oxy. All the rest of the cut is wonderfully smooth. Just this one place is a blob.

    Sometimes, I get a popping noise in the torch, and I'm not cutting or adjusting. It just pops. What causes that? Same settings.
