In any discussion about how to cut metal, plasma cutting is right up there with laser and waterjet. The technology gets a bad rap, though, when the discussion turns to cutting aluminum. There are five preconceptions that many fabricators have about turning to plasma to cut aluminum. But according to three experts, new plasma cutting systems produce good results on aluminum.

Denman & Davis calls itself the largest general-line, independent service center in the Northeast. The company has about 65,000 square feet of inventory and manufacturing space in Clifton, N.J., another 70,000 square feet in Slatersville, R.I., and another 35,000 in Albany, N.Y. The company distributes a variety of hot-rolled and cold-finished bars, structural shapes, sheets, and tubing, but has discovered a fruitful niche with plate, used in pressure vessel, power generation, and processing applications.

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.
