Industrial grade oxygen is commonly used with a fuel gas for cutting, welding, brazing and soldering as it supports combustion and gives much higher flame temperatures than if air is used. For cutting with oxygen an oxy-fuel flame preheats the steel to its ignition temperature further to which gaseous oxygen flows onto the red-hot steel, generating more heat and melting the steel.
