    Actually Jon, If your torch outfit is a Victor you may already have a grade T hose. Victor Equipment has been shipping grade T hose in their cutting outfits for the past few years. If you look on the hose it should read "acetylene only" or " all fuel gases". If you can't read it play it safe and replace te hose with a grade T hose. Then just changed out your tip to a propylene tip and you are set.
    Important thing to remember: you can use an acetylene regulator for propylene, but you can NOT use a propylene/propane regulator for acetylene. The reason for this is because propylene/propane regulators have the ability to be used at a higher pressure than 15 PSI. It is ILLEGAL to use acetylene at anything higher than 15 PSI.
    It's not illegal, it's just very stupid

      Trademark name for propylene... http://www.airgas.com/browse/product...&WT.svl=117198

      Trademark for Chemweld (Atlanta Georgia) propane product, with propylene: http://www.msdsonline.com/binder/sco...000/000182.pdf

      Apparently, it is, or contains, propylene.

      Chem-O-Lene: Care to give a polite, relevant, explanation rather than a caustic, nasty, and apparently wrong diatribe, in response to a thread that is over a year old?

      Also, Acetylene is not a hydrocarbon blend. It is C2H2, ethyne, a pure hydrocarbon. As provided for chemical industry use and welding service, the purity is quite high, with fairly tight controls on impurities even with the lowest grades.

          I'll throw in my $0.02 since somebody else dug this up.... I have actually used Chem-o-lene. Bought a 10? lb can 15 years ago still have half of it... The pro's 1 No soot, 2 It will burn through multiple layers without blowing back.

          The con's 1 You need to buy all new tips, I know some of you probably have one crusty old cutting tip, but my box of tips weighs about 40 lbs. 2 It will burn through multiple layers (good luck cutting a bearing off a shaft) 3 The cuts are not as precise as O/A. 4 The cutting tips are more expensive and much more tender (basically a propane tip).

          Other thoughts... The tanks are a propane tank and have the same recert rules, They don't fit in your cart either. The supplier I had bought the gas from was pushing it fairly hard back then, now they don't handle it anymore.

            NO SOOT!!!!!!!!!!! Heck with that

            If it wasn't for the "soot trick" I may have stopped using O/A all-together.

              In looking at the MSDS sheets in the links I am suprised to see that the % of the gasses other than propane vary so much. Are they there to tune the propane or just hard to filter out?

                I work in the propane unit and have been the control room guy making the stuff. There is so many variables that enter in making any gas. Like sweet crude, sour crude, crude mixes because you just don't run one tank of supplied crude anymore its all mixed from 4,5,6,7 tanks of raw crude from all over the world. So every hour the process is changing and you have to make adjustments. We have target sheets that we have to meet 6 or 8 times a day and they may vary a little...Bob

                  will propane weld the same as name brand Cemoline? the "other gasses" seem to each range in the 2% to .5% range. Sounds almost like byproducts or manufacture or min levels that can be filtered at reasonable cost kins of stuff.
