Plasma cutting is a useful and often less-expensive means of cutting materials when compared with other means, such as laser cutting. High definition plasma cutting systems use ionized gas to cut through materials. The ionized gas (plasma) melts the material, and then the force of the gas through the torch blows it clear of the non-melted or cut material. The cutting tool, or torch, is controlled by a CNC machine, which allows for precise and accurate cuts in the material. Plasma cutting has come a long way in recent years, and it is continuously becoming a faster and more precise method.
