What can occur if the flame is adjusted too high during oxyfuel cutting?

When the flame is adjusted too high during oxyfuel cutting, the flame becomes less stable. A high flame can lead to an exaggerated flickering or even sputtering, which disrupts the focus and intensity of the heat. Stability of the flame is crucial because a stable flame ensures consistent heating of the metal being cut. When the flame is unstable, it can cause fluctuations that affect the cutting quality, leading to incomplete cuts or irregular kerfs.

In oxyfuel cutting, achieving the correct balance between the oxygen and fuel gas is essential for optimal performance. An excessively high flame does not contribute to better penetration; rather, it can lead to overheating of the base material, potentially causing warping or unwanted burn-through. Stable flames enable controlled cutting, allowing the operator to maintain accuracy and depth. Therefore, maintaining flame stability is critical for effective and precise oxyfuel cutting.
