Alone or assisted with water, plasma has proven itself to be one of the most efficient cutting processes for sheet, plate, tube, pipe, and profiles. Search this technology area for information on equipment, cutting tips, and gases.
Plasma cutting has become a process of choice for many because of its cost-effectiveness. However, this wasn't the case when the technology was introduced because of short consumable life. Technological innovations over the years, however, helped to change that.

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.

C&S Metal Fabricating, Houston, fabricates parts for the oil and petrochemical industry. When it purchased a thermal cutting table with the latest controller technology, it took the unusual step of keeping all nest designs down on the shop floor, not in the front office as many other shops do.

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.
Plasma arc cutting systems come in many capabilities. Knowing what those capabilities are and which ones you need for your operation is crucial when choosing a system.

If you are considering retrofitting existing equipment to not just expand your plate cutting capacity, several factors need to be considered. These factors focus on a higher wattage resonator or an higher amperage plasma system, but also on the need to review the entire machine architecture.
