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.

The historic High Roller roller coaster, perched atop the Stratosphere Tower on the Las Vegas Strip, needed to be demolished. The question for contractors was what cutting process and equipment would be best to dismantle the roller coaster, all 367, 3-foot, 300-lb. sections of it.

One job led Keller & Son Industrial Contractors Inc., Spartanburg, S.C., to buy a new plasma cutting table in 2001. The need for extra capacity required it to purchase another in 2006. Now the company feels it is in the perfect position to take on all types of metal fabricating jobs.

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.

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.

Just 20 years ago most heating, ventilation, and air-conditioning (HVAC) ductwork was cut by hand with snips and shears. Cutting out HVAC fittings was slow and labor-intensive. It took an experienced tinsmith with strong hands to slice through galvanized steel all day. It took even more skill to get the cuts and bends just right to coax flat panels of sheet metal into precise 3-D forms.

Many fabricators use plasma arc cutting torches every day, either to replace or complement saws, cut-off wheels, snips, and oxyfuel rigs. It can be used in a variety of applications—installing or remvoving HVAC/R equipment, plumbing systems, and industrial equipment; reparing equpment and systems; and cutting shapes consistently.

In comparing cutting costs associated with precision plasma, punch-plasma, and laser cutting, it's important to account for labor costs, operating costs, and depreciation. All three of these processes have benefits and drawbacks cost-wise, depending on how they're deployed.
