What is the maximum effective cutting distance for oxyfuel cutting?

The maximum effective cutting distance for oxyfuel cutting is often considered to be around 4 feet. This distance is important because oxyfuel cutting relies on a concentrated and carefully controlled flame to effectively melt and blow away the metal being cut. When the distance between the cutting torch and the surface being cut exceeds this effective range, the quality of the cut tends to diminish significantly.

At greater distances, the flame begins to diffuse, leading to a wider and less intense heat concentration. This can result in inadequate heating of the metal, poor melt quality, and increased risk of dross formation, making it difficult to achieve clean and precise cuts. Additionally, maintaining the correct distance allows the operator to have better control over the cutting process and ensures that they can follow the desired path more accurately.

While options suggesting shorter or longer distances are presented, they do not align with the optimal range for maintaining efficiency and cut quality during oxyfuel operations.
