A dry filtration system for plasma cutting removes all potentially harmful contaminants from the shop air and helps to eliminate the threat of a dust explosion. It also might prove to be a much more effective plasma cutting approach when compared to plasma cutting on a water table.

It used to take days or weeks to program a robotic plasma cutting cell. Now, like in welding, robotic plasma cutting has become much more flexible and adaptable. Offline programming and simulation, as well as flexible components of the robot cell itself, have made this possible.

It's not unusual to see shops replace at least some plasma cutting consumables at the start of every shift, but some of these consumables should last 50 shifts or more. Getting the most out of your consumables goes back to the basics: proper inspection and preventive maintenance.

Great Lakes Shipyard, Cleveland, added a plasma cutting machine to its fabricating operations, which helps it to make more of its own parts without relying on subcontractors that don't always meet delivery dates.
New equipment technology and better understanding of gas selection make it possible to cut stainless steel productively using the plasma cutting process.

Metal fabricators with plasma cutting equipment that is 10 years or older may be surprised to learn just how far plasma cutting has come. The technology has evolved to the point that outside edges are smoother than ever, and precision holes can be cut to accommodate fasteners.

Initially used for nonferrous cutting operations, plasma developed into a useful means for cutting 2-D sheet and plate steel when the water-injected plasma process was developed in the late 1960s. As technology developments improved the edge quality, cutting speed, consumable parts life, and long-term operating cost, it became competitive with other thermal cutting processes. In recent years, improved control technology has enabled plasma to be a contender in the realm of 3-D cutting, making it an option for tube, pipe, and profiles.
Fabricators mark parts for various reasons using different technologies, each with its own benefits. This article describes several marking options and further discusses plasma marking.
