In oxyacetylene torch cutting, what is the typical cutting pressure measured in kPa?

In oxyacetylene torch cutting, the typical cutting oxygen pressure is usually set within the range of 50-70 kPa (7-10 psi). This pressure provides an optimal balance that ensures sufficient oxygen flow for combustion, allowing the flame to reach the necessary temperature for cutting through metal effectively. This range is critical because if the pressure is too low, the cutting process may be inefficient, leading to poor-quality cuts and possible issues with the metal being cut. Conversely, setting the pressure too high could result in excessive oxygen flow, causing instability in the flame or even safety hazards. Therefore, maintaining the pressure within this specified range ensures that the cutting torch operates safely and efficiently while achieving the desired results during metal fabrication or repair tasks.
