What is the most important gas in the oxy-fuel cutting process?
Without a doubt, the correct answer is 'Oxygen'.
It supports the flame during the preheating stage, bringing the carbon steel to incandescence, thus fueling an exothermic reaction between the carbon contained in the steel and Oxygen. However, the fuel gas also has a fundamental role in the type of operation and the economy of the process. Depending on the type of cut to be performed, it is possible to choose the most suitable fuel gas.
