Why is it crucial to maintain a proper nozzle size on the cutting tip?

Maintaining a proper nozzle size on the cutting tip is crucial because it directly influences optimal cutting efficiency. When the nozzle size is appropriate for the specific type of material being cut and the desired thickness, it allows for the right amount of oxygen to be delivered to the fuel gas, enabling a focused and effective cutting flame. This ensures that the flame can sufficiently reach the ignition temperature of the metal, allowing for smooth and clean cuts without wastage of fuel or excessive slag formation. An improperly sized nozzle can lead to poor cutting performance, inconsistent cuts, and possible safety hazards due to an unstable flame. Hence, achieving the best cutting results and efficiency is highly dependent on the correct nozzle size.
