What should my oxygen and acetylene gauges be set on?

The recommended setting is for the fuel gas regulator to be set at 10 psig and the oxygen regulator at 45 psig. This recommendation applies when cutting less than 1.5 inch steel with the use of propane, propylene or natural gas.

What is the ratio of oxygen and acetylene in gas welding?

For the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1,2 to 1 for acetylene and 4.3 to 1 for propane.

What pressure should acetylene gas be used at?

To prevent decomposition during use, acetylene gas system pressures must not exceed 1.5 barg (22 psig). Acetylene is principally used for oxyacetylene cutting, heat treating, and weld- ing.

What PSI does he set the oxygen and acetylene on the torch at for fusion welding?

Common pressures for cutting are 40 psi for oxygen and 10 psi for acetylene. Open the blowpipe acetylene valve about ⅛ of a turn then light the torch with a friction lighter. Increase the acetylene until the flame is just ready to leave the tip. Open the oxygen preheat valve until a neutral flame is obtained.

What should my oxygen level be?

A normal level of oxygen is usually 95\% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90\%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95\%, call your health care provider.

What is the ratio of oxygen to acetylene in carburizing flame?

Carburizing Flame : It has more of acetylene content than that of oxygen, approximately 3:1.

What is the ratio of acetylene to oxygen in reducing flame?

one-to-one ratio
The neutral flame has a one-to-one ratio of acetylene and oxygen. It obtains additional oxygen from the air and provides complete combustion.

What pressure should oxygen and acetylene be set at for brazing copper?

Oxygen and acetylene should be set at equal delivery amounts depending on the size and mass of the object being brazed. This would translate into 5 psi oxygen and 5 psi acetylene. These pressures are delivery pressures that must be set as the gas is flowing from the torch tip.

What is the correct working pressure for oxygen when welding?

10 to 40 psi
The oxygen pressure ranges between 0.7 to 2.8 bar (10 to 40 psi), depending on the size of the torch tip. A jet of relatively high-pressure oxygen produces the suction necessary to draw the fuel gas into the mixing head. The welding tips may or may not have separate injectors in the tip.

How do you set an oxygen acetylene torch?

1. Separately purge both oxygen and fuel gas lines.
2. Open fuel gas valve 1/2 turn.
3. Ignite flame with striker.
4. Increase fuel gas flow until flame leaves end of tip and no smoke is present.
5. Decrease until flame goes back to tip.
6. Open oxygen valve and adjust to neutral flame.
7. Depress oxygen lever and make necessary adjustments.
