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.

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

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

    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.

    YEAH!!!!!!!! what HE said!!!!!!!! Interesting someone can be so rude (I'm being VERY polite!!!!!!!!!!!), not seem to back themselves up, so we can all learn, eh?

    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.

    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.

    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

    Those who tell you it is a propylene are wrong.

    Propylene will get to 5300 degrees max, Chem-O-lene will burn at 5800 degrees.

    Propylene is a residual product from refining crude oil, Chem-O-lene is a Hydrocarbon blend like acetylene but is carried by propane as opposed to acetone in acetylene.

    It is a cleaner, safer gas and performs well in comparison to acetylene. It costs about half of whatr acetylene will cost.

    I don't know when i have seen such a complete array of incorrect info.
    OK Chem-o-lene is not propylene. Other than that what was incorect in the posts about propylene? How does you brand name gas outpeform propylene and where can you get it? This is not a jab it is real question and I would like to know more as I am planning to do a lot more gas work in the future.

    Thanks. Unfortunately, my Victor uses a RM hose. But my Nortel bench burner has a T hose.

    Thanks for the clarification. Keep hearing that acetylene is on its way out -- especially here in Hawaii. But can't seem to get any clear consistent info on alternative fuels. The gas supplier (gaspro/airgas) tells you one thing and the torch rep (victor) tells you something else

    If I change to Type T hose and propylene cutting tip, will I be able to use my same equipment? Or is there more? If so, how much more?

    I already have 2 setups -- 1 for my OA torch and 1 for my oxy-propane lampwork torch. Last thing I want in my very very small space is a 3rd setup for alt fuel. I'm just trying to do some artwork, I don't plan on opening my own welding business
