Oxyfuel Cutting: Effect of Oxygen Purity

PCI Gases’s Erin Meehan and Frank Vonesh recently authored an article comparing the use of vacuum swing adsorption (VSA) oxygen to the use of cylinder oxygen for oxyfuel cutting steel. Depending on equipment set-up, VSA oxygen has the capability of performing at higher cutting speeds than cylinder oxygen can. To access the full published article from the Gasworld US October 2016 Issue, click here.

Cutting with VSA oxygen provides a constant flow of oxygen. Shown here is cutting done with diesel fuel and VSA oxygen on a 1.125-in. steel plate.
