Oxy-Gasoline cutting?

admin

Oxygen and fuel gas mixtures work for cutting steel, no doubt. I watched half of this video before it dawned on me that they are cutting with oxy-gasoline rather than oxy-acetylene.City of L.A.

Reply:The gasoline torches don't really perform better than any other torch systems.  They're certainly more cost effective than acetylene if you do a lot of cutting.  But, propane rivals gasoline in cost and is also very effective.  Propane is more widespread and tips/torch parts are usually easier to get.

Reply:Boilers make 3200 degree F furnace temps with athmospheric air and a little forced draft.  A lot of things burn really hot when you do it with pure oxygen.

Reply:"white gas "   ...was just a low octane (about 50 ) UNleaded gasoline , maybe about like naptha . but, it burned very clean ,was great for ancient  outboard motors .[SIZE="5"Yardbird"

Reply:They were just going out of style when I started scouting, pump, pump, pump! I never got to use one. We used a butane burner, midget looking thing that sat about 5 or 6 inches high with one little burner on top, throw away tank under it, forgot the name of them things.City of L.A.

Reply:I have a collection of Coleman lanterns, and stoves, all of which are older than me. They all work like a charm, and when out of fuel gasoline works. I vote propane for cheap cutting, I use it all the time.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:welding EXPERTS once did a study for me ,as to cost of acetylene  VS. propane for burning . acetylene came out as cheaper (somewhat) ,faster ,etc.  NOW....... having said that, IF a large shop uses a VERY large propane flask (like 500  or 750 gallon tank, ,then it can be much cheaper to use on gang burning machines (multiple torches on one machine) , along with liquid oxygen . At MARE ISLAND  welding shop(before the navy shut it down, ) we had a 2000 gallon liquid ox  tank, and a 750 gallon propane tank.[SIZE="5"Yardbird"
Reply:That study may have been done a very long time ago.  At current prices, propane is about 1/7th to 1/10th the cost of acetylene (fuel only) according to the welding experts I have talked to.  Propane may burn more O2, but O2 is cheap.Mare Island, huh?  I live near there.  We go "exploring" (no stealing, just looking) at night, sometimes.
