Could you do more with your plasma cutting system?

October 11, 2016 | By Harry Mellott, Shreyansh Patel

Modern plasma systems can do more than just cut. They can gouge, mark, remove welds, and more. And this applies whether plasma processing occurs using a hand-held torch or a machine torch mounted on a CNC table, robotic arm, or automated track.

Using dry filtration to capture plasma cutting fumes

August 31, 2016 | By Josh Delson

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.

Robotic plasma cutting gets flexible

July 29, 2016 | By Tim Heston

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.

Plasma cutting maintenance: Are you throwing money away?

March 2, 2016 | By Jim Colt

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.

Plasma cutting meets biochemistry

September 8, 2015 | By Tim Heston

A fluid for plasma cutting tables is designed to coat workpieces to prevent rust and corrosion. The fluid effectively biodegrades bacteria on contact. The company also reports that the fluid is safe enough to send down the sewer.

3-D plasma cutting in a 2-D world

September 1, 2015 | By Dan Davis

R.J. Cyr Co., Maidstone, Ont., had a job for which it needed to cut sections of structural steel beam, but it couldn't do the job profitably relying on a manual approach. After consulting with its plasma cutting table supplier, the company devised a way to add CNC cutting capability into the mix.

Putting heavy-duty cutting on the table

May 28, 2015 | By Steve Zlotnicki

Thermal cutting of plate can produce a haze in the shop, but does it have to be that way? Table options can help to clean up the plasma and oxyfuel cutting process and create a better work environment for fabricators.

Plasma cutting torches: the long and short of it

April 2, 2015 | By Michelle Avila

Plasma cutting torches have come a long way from the first-generation squared-off, clunky hunks of plastic that looked like a child’s toy hammer. Today’s high-tech torches come in various models for different applications.

The evolution of plasma cutting

January 17, 2014 | By Jim Colt

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.

Plasma cutting for tube, pipe, profiles -

Plasma cutting for tube, pipe, profiles

July 11, 2013 | By Jim Colt

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.
