Rob, in the past years, I have burned many a tank of MAPP, many more of propylene and because of the mindset of todays construction industy,acetylene by the truck load. The conclusion I have had is, actylene, the fast gas. Heats fast, gets used up fast, gets tips dirty fast, and because it self explods at 27.9 lbs in the right conditions, will get you killed fast. Propylene, less heat means waiting a little longer, but still allmost as expensive as act. MAPP,a little colder still, but less cost. The 2 latter gases are propane with added hydrocarbons to make propane burn hotter. There is a couple more brands out there but just propane with the stuff in it so they can mark up the price. Propane and natural gas are about 500 to 600 degrees colder than act. Takes a little longer, but propane is 1/4 the cost of act. and will last 5 times as long, no joke! Big outfits, with lots of thick cutting, use natural gas, but us home town boys have propane. Throw away your tip cleaners,very safe to use, cleaner cuts, less grinding. I am like rick, keep act. for welding or for carborizing the surface of a tool, and ofcourse for filling garbage bags on 4th of july. Did I just say that? Shame on me.
