What is the ideal pressure range for the oxygen cylinder in oxyfuel cutting?

The ideal pressure range for the oxygen cylinder in oxyfuel cutting is between 20 to 40 psi. This pressure range is important for several reasons. First, at this pressure, the oxygen can effectively fuel the cutting process, ensuring that the flames are hot enough to melt through the metal being cut. If the pressure is too low, the combustion may not be sufficient, leading to poor cutting quality and slower cutting speeds.

Moreover, maintaining oxygen pressure within this range helps achieve a steady and stable flow of gas. This consistency is crucial when cutting, as fluctuations in pressure can lead to disruptions in the flame stability, affecting the overall performance and safety of the cutting operation. Pressures above this range, such as those in the 50 to 70 psi or higher categories, can be excessive for most cutting applications and could potentially increase the risk of flashback or other safety hazards.

Thus, the 20 to 40 psi range is recommended as it strikes an optimal balance between efficient cutting performance and safety while utilizing the oxyfuel cutting process.
