Reply:A good combination is to have flashback arrestors at the regulators and check valves at the torch end.  The check valves are nice because they don't add a lot of bulk at the torch end.And these are the arrestors.
Reply:When you inspect torches, keep an eye out for indications of internal fire damage such as heat discoloration.This now-much-shorter Victor mixer left parts of itself in the tube when it melted. I guess the Smith and Airco designers have a point. Tip-mix torches don't do this: Attached Images
Reply:good post...this is good to know...i always lite my torch with mixed gas so it does have all the black smoke.

Reply:I would recommend investing in a newer torch with built-in flashback arrestors and reverse flow check valves.  It is too easy to get in a hurry and not take the time to put these in the line to the regulators separately.Ranger 225Weld Pac 100Power Mig 180CMagnum 100 Spool GunHobart EZ Tig 165iSurf for cardiovascular exercise.  Saltwater is good for you.
Reply:under what circumstances would anyone use acetylene over 15lbs? i find 10 lbs works fine for everything from sheet metal to 3" plate by changing the cutting tip to the correct size.

Reply:Just reposted it Steve.  Someone else did awhile back and I think the entire video series on proper setup and use should be a must watch for newbe OA torch users as well as a refresher for seasoned operators.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!

Reply:I was thinking of putting flashback  arrestors on my Victor  med. duty torch handle but the 3/8 sizxe seems nonexistent.Maybe I am missing them but all seem to be 9/16.Doing the best I can with what I got
Reply:Thanks to the member that originally provided Zapster with the link that started this thread.Way too many guys using torch rigs and don't know how close to a (catastrophic) failure they are at.How do you know the blacksmith's dog? When you hollar at him he makes a bolt for the door!
