Hi DickPopping is caused by burning too small a flame on too big of a tip. use a smaller tip which will give you a smaller flame but still keep the flow of gas up enough to cool the tip.

Dick,Torch popping/backfiring is often caused by:1. Holding the inner cone of the flame too close to the puddle, thus overheating the tip.2. A partly clogged, or dirty, tip.3. Using too large a tip for the job, and reducing the gas flow too much in order to avoid totally melting the work piece.Possible solutions:Keep tips clean and use the recommended tip pressures for the tip size you are using (this may vary with the make of the welding outfit). Keep inner flame cone clear of the puddle (try 1/8" to 1/4" clearance and find what works for you). Don't use too large a tip for the job and try to throttle it back; take the time to switch to a smaller tip, rather than trying to manage with the too-large tip.Good luck!Graham Hansen (Pietenpol CF-AUN)________________________________________________________________________________

Hmmm, I wonder if this technology could be adapted to my circa 1950 Cast Iron Craftsman table saw.Glenn W. ThomasStorrs, CThttp://www.flyingwood.com ----- Original Message -----
