By optimizing the performance of each of the plasma cutting system's components, a fabricator can quickly and consistently create high quality parts. The plasma power supply, torch, and lead assembly comprise a plasma cutting system. Robust cutting applications require a mechanized system with an integrated computer numerical control (CNC) and a three-axis configuration with the plasma torch and a torch height control.

Some tips and suggestions for best practices that will increase your efficiency and precision and prolong the life of your plasma cutter and consumables include: Take the time to read the manual thoroughly; develop a "preflight routine" visually follow the arc that is coming from the bottom of the cutâthe arc should exit the material at a 15- to 20-degree angle opposite the direction of travel; and maintain a 1/16- to 1/8-inch distance between the tip and the workpiece.

For many people, the world of plasma cutting is a complex and daunting place, with a cryptic set of rules that can be mastered only by highly trained technicians after weeks of training. For every change of material or thickness being cut, a long process ensues of resetting gas mixtures, tweaking pierce heights and pierce delays, and manually calibrating every last parameter to ensure a reliable result.
