How much time can I cut with a size 23 acetylene cylinder and a size 22 oxygen cylinder?
TM Products Catalogue. A size 23 acetylene contains roughly 130 cubic feet of acetylene, and a size 22 oxygen contains 125 cubic feet of oxygen. The POCKET GUIDE FOR OXY-FUEL GAS WELDING, CUTTING, HEATING, AL literature number 1140-322A, tells us that an 802 size 0 tip will consume approximately 45cfh of oxygen and 12 cfh of acetylene to cut ΒΌ inch material. The limiting factor, in this case, is the oxygen which will last approximately 3 hours, whereas the acetylene will last approximately 11 hours.
