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.
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.

CNC plasma cutting machines are more affordable and easier to operate than ever before. By knowing the right kind of hardware and software makes sense, a fabricator can choose the equipment that makes the most sense for his operation.
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.

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.

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.
