About Plasma Cutting
The technology behind plasma cutting involves a thermal cutting process in which a beam of ionized gas, or plasma, heats an electrically conductive metal beyond its melting point, then blows away the melted material, leaving a hole or a cut. As a plasma torch is moved across material a cut is made, much like that of a saw blade. Plasma cutting can be done using a hand held torch, however a table mounted plasma cutter with a computer controlled gantry system can be used for a higher degree of accuracy for more complicated cutting operations.
