What is the difference between oxygen and acetylene cylinders?

Last Updated: 7th April, 2021

Acetylene is a Class 2.1- Flammable Gas, can react dangerously with oxidising agents and may explode if heated. Pure oxygen gas is usually supplied in black cylinders and comes in a range of purities: industrial grade, food grade, ultra high purity, dry breathing extra high pressure etc.

Beside this, what should my oxygen and acetylene be set at?

Check the manufacturer's instructions, but generally the acetylene should be set to about 10 psi and the oxygen should be set to about 40 psi.

Subsequently, question is, when using oxygen and acetylene cylinders open the valves? Always keep cylinders in an upright position. Oxygen cylinder valves must be opened all the way. Do not open acetylene cylinder valves more than 1 turn (1/4 to 1/3 is usually enough). Turn pressures into gauges gradually.

Also Know, how do you identify acetylene cylinders?

In industrial applications acetylene cylinders are maroon coloured, and with a left thread. The oxygen cylinders are black, and have a right-handed thread. That way you cannot get the regulators and hoses mixed up.

Do you use more oxygen or acetylene?

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. So, there is far more oxygen being consumed when using Propane. Despite Propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.

What do you turn off first oxygen or acetylene?

It's typically recommended that when finishing with the use of an O/A torch, you shut off the acetylene first, then sut off the oxygen. I realize that this extinguishes the flame immediately, because the fuel gas is gone.

What is the working pressure of acetylene?

The pressure of acetylene in an acetylene cylinder can be as high as 250 psi (1724 kPa). A gas pressure regulator will automatically deliver a constant volume of gas to the torch at the adjusted working pressure.

How do you set an oxygen acetylene torch?

How to Set Up an Oxy-Acetylene Torch
  1. Secure the oxygen and acetylene tanks in the torch cart.
  2. Remove the covers protecting the tank valves and attach the regulators to the valves.
  3. Attach the hoses to the regulators.
  4. Connect the other end of the hoses to the torch handle.
  5. Turn the valve on the oxygen tank completely open.

Why is my torch popping?

The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage. In short, it could be a number of things.

How do you make 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.

How do I know if my acetylene tank is empty?

You can see if a cylinder is empty by checking the cylinder pressure registered at the gauge* on primary regulator. colour coded), the cylinder is empty • change it for a full cylinder of the same type.



What is the ratio of oxygen to acetylene in a neutral flame?

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

How are gas cylinders identified?

The permanent stamp on the cylinder neck is the primary means of identifying the contents of a gas cylinder. The distinctive colour and a label on the cylinder neck also help to identify the cylinders.

How do you identify a nitrogen cylinder?

If a flaming wooden splint or piece of paper is inserted into a tube of gas and the flame immediately goes out, then the gas is nitrogen versus oxygen (oxygen would feed the flame). If a wet piece of pH paper is inserted into a tube of gas and shows no change, then the gas is nitrogen versus carbon dioxide.

How do you identify a cylinder?

There are two ways to identify a cylinder. The first way is by the part number. Typically, there will be a stamp or a plate on the cylinder with a 5 to 10 digit part number on the cylinder. Also, finding out the manufacturer will help a great deal.

What happens to acetylene above 15 psi?

Acetylene will not explode under low pressure at normal temperatures. However, it becomes unstable and spontaneously combustible when compressed to a pressure over 15 psi. Beyond 29.4 psi, it becomes self explosive, and a slight shock may cause it to explode even in the absence of air or oxygen.

What happens when you mix oxygen and acetylene?

Needs only 10% mix of oxygen to ignite. It is an unstable gas, will violently decompose when in a pure state above 15 psi. What Is Acetylene? This means if acetylene reaches 30 psi in a free state, it can explode by itself without a spark or flame being present.

Do you turn off the oxygen or acetylene first?

We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.

What would happen if acetylene is used with the wrong tip?

What can happen if acetylene is used on a tip designed to be used with propane or other such gas? Tip may overheat, causing backfire or the tip explodes.
