How The Plasma Cutter Works

A plasma cutter works by way of sending pressurized gas down a tiny channel that is in the cutting nozzle. At the center of this nozzle, the channel is found an electrode that is negatively charged. As power is applied, and the tip of the nozzle is touched to metal that is positively charged, this connection completes a circuit with a powerful spark. Gas passing through this channel provides a spark and heats up the gas to the point of the before-mentioned fourth state.

The temperature of this state of matter can reach an amazing 30,000 degrees Fahrenheit which makes a plasma cutter able to cut through just about anything just like cutting through butter.

With the high-velocity plasma flowing from a negatively charged electrode and one that is positively charged and created by plasma cutters you can see the efficiency of the operation.

When using a plasma cutter you will find that the metal that is not in the cutting area will stay rather cool, and this prevents the kind of warping and damage to the paint that can be seen with typical cutters using a flame. Plasma cutters are about five times as fast as traditional welding torches, and they are not reliant on gases that are flammable. They also come in handy when you use them to pierce or gouge metals speedily and with accuracy.
