4 Oxy-Acetylene Hoses. COLOR CODED: Red= Acetylene (Flammable) Green = Oxygen
5 OxygenOxygen-a colorless, odorless, tasteless gas that is heavier than air. Oxygen alone will not burn, but when mixed with other combustibles it becomes highly explosive.
6 Oxygen is stored as a compressed gas in a steel cylinder to a pressure of 1,800 to 2,200p.s.i. Turn Cylinder valve open completely
7 Oxygen Regulator Right Handed Threads Regulator has Female Connection, Cylinder has Male ConnectionWorking pressure between 20 and 60 psiWe (Ag mech) will use 20 psi
8 AcetyleneAcetylene-is colorless, but has a very distinct odor. This gas is compressed to a pressure of 250 p.s.i. It is composed of carbon and hydrogen.Turn Cylinder Valve 1/3 or 1/4 turn open.
9 Acetylene Regulator Left Handed Threads Regulator has Male Connection with “V” groove, Cylinder has female Connection.Acetone is added as a Catalyst.Working pressure between 2 and 10 psiTank pressure, 250 psiWe use 5 psi
10 Oxygen & Acetylene Cutting Is a process used to separate metal by heating it to a melting point, somewhere between 1,400 and 1,800 degreesThe metal is then oxidized and blown from the kerf with a stream of pure oxygen
11 Oxygen Acetylene Safety Oxygen supports combustionCylinders are necessary but can also be highly dangerousAlways cap bottles in transportCylinders can explode
12 Oxygen Acetylene Safety Cont.. 5. Acetylene bottle should be emptied at a rate of 1/7th capacity per hour or less6. Flames can reach 6,300 degrees F7. Bottles should be stored in a vertical position at all times.
13 Cutting Tips Tips are sized by metal thickness Adjust pressure to fit metalCone of flame does not touch metalPopping tip means:too close, not enough oxygen, too hot, or dirty tip
