What are the gas pressures for cutting?

Recommended oxy/ fuel gas (propane, propylene, natural gas) cutting tip pressures also vary widely with size. If you have no manufacturer setting- information, and are cutting less than 1 ½” steel, set the fuel gas regulator for 10 psig, and the oxygen regulator for 45 psig.

What is the working pressure for oxygen when cutting?

Safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of tip size. Simply adjust them until you get a neutral flame.

Why LPG is not used for gas cutting?

Firstly: Propane cannot be used for Gas Welding. When acetylene burns in oxygen, it creates a reducing zone that cleans the steel surface. Propane do not have a reducing zone like acetylene and can hence not be used for Gas Welding.

What pressure do we set oxygen regulators to?

Oxygen and acetylene regulators reduce pressure and control the flow of gases from the cylinders. The pressure in an oxygen cylinder can be as high as 2200 psi (15,169 kPa), which must be reduced to a working pressure of 1 to 25 psi (6.90 to 172.38 kPa).

What is the range of pressure gauge used in an oxygen cylinder used in gas welding?

0 to 300 bar
Oxygen Cylinder Pressure Test Gauge, 0 to 300 bar(0 to 4000 psi)

What pressure do you set a cutting torch?

The gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length …

Which is safer LPG or acetylene?

Acetylene will ignite at mixtures from 2.5 percent to 82 percent, while the range for propane is 2.1 percent to 9.5 percent. Based off of these numbers, it’s easy to argue that propane is much safer to use than acetylene.

What pressure should oxygen and acetylene be set at?
