What is a necessary condition for oxyfuel cutting to occur?

For oxyfuel cutting to occur effectively, a proper mixture of gas and oxygen is essential. This process involves combining a fuel gas, typically acetylene, with pure oxygen in the correct proportions to achieve a flame hot enough to melt and oxidize the metal being cut. If the mixture is not correct, the flame won't reach the necessary temperature for cutting, which usually requires temperatures around 3,500 degrees Celsius (6,332 degrees Fahrenheit) or higher.

An improper mixture could lead to insufficient heat for effective cutting or even result in an uncontrolled reaction. Thus, achieving and maintaining the right gas-to-oxygen ratio is crucial for both performance and safety in oxyfuel cutting operations.
