Plasma Cutters

Plasma cutters use an electric current to create an accelerated jet of hot plasma. This heats and melts the metal, with a jet of air blowing away the molten metal. A plasma gas (often an Argon mix) is also consumed during the cutting operation. Plasma cutters produce a very clean cut and are very easy to use. CNC models are available that can cut very complex designs from large sheets of metal in minutes.

Use

The plasma cutter is almost a “point-and-shoot” activity, but there are a few things to know before you use one. The video below does a good job of showing how to perform a basic cut.

Safety Precautions

The main safety hazards are flying hot metal and UV exposure. Protective dark eyewear, gloves, and clothing should be worn. Be careful not to allow the cut parts to fall on your feet when cutting.
