How Plasma Cutters Work?

Plasma cutters cut metal using a plasma torch. For it work, plasma (the fourth state of matter) has to be created. Plasma is a super-heated (15,000 degrees Celsius) substance that is a gas and a liquid at the same time. Two things are required to create plasma, a gas and a heat source.

The old versions of plasma cutters (plasma cutting was invented during World War II) started the arc with high frequency, high voltage circuits. You can browse https://www.easterncompositeservices.com/machining/ to know more about the plasma cutting service.

This means that the operator risked electrocution if they were not careful. Also, these old machines are difficult to repair and maintain.

A plasma cutter can cut metals of different thicknesses. The size of the machine is what determines the sever cut. “Sever cut” is the standard used to define the thickest possible cutting potential for a given plasma cutter.

The thicker the metal to be cut the easier it is for a CNC plasma cutter to operate. You have to watch out though, the closer the metal thickness comes to the sever cut rating of a plasma cutter the messier the cut may be. This means you may have to clean up the edges after you are finished cutting.

Since CNC plasma cutters are computer controlled they are very precise. For very repetitive projects or industrial applications a CNC plasma cutter is must. These machines can do the same thing over and over and over all day long.
