What is oxygen cutting?

oxygen cutting is the practice of introducing oxygen to increase the temperature of the cutting gas, such as acetylene. By introducing oxygen into the flame over the head cut, heat increases and the operator is able to tune the cutting flame to create the desired effect. Cutting oxygen also uses compressed oxygen to throw away the liquidated metal from the path of the cut. The practice of oxygen or oxylene oxylene, as is commonly called, makes the dense steel cutting an easy task at almost any place of employment. Most construction sites around the world have at least one acetylene oxygen cutting system in place. Like blowing to the campfire to burn the material, the introduction of oxygen into any fuel gas increases the floor to which it burns. Propane is often used in cutting torches instead of more expensive acetylene. This is partly due to the ability to create a warmer flame with a propane that allows it to cut the metal.

oxygen cutting also saves gas. The amount of gas used to create a cutting flame is less than half the amount of oxygen used. Acetylene is only used to create a base fire on the burner's head and oxygen is used to treat the heat level at the tip of the flame. The flame is modified from matte orange to bright blue by adding oxygen to the gas mixture. When using the system to the gas weld, oxygen is added until the long flame becomes a short concentrated fire.

When adjusting oxygen cutting torches, oxygen is treated in two ways. The gas is ignited and modified until no black smoke comes from the flame. The oxygen is then added to the flame until the flame does not burn bright blue, which means that the temperature is the hottest. Finally, the oxygen cutting valve is set until the flame becomes a short, bright blue color and the flame does not change too much when the lever is pushed. This creates a loud blowing sound that cleans the cutting path of any residual molten metal.
