How Plasma Cutters Work

You can cut metals using a plasma cutter that utilizes a plasma torch. You have to create a plasma in order for a plasma cutter to work. The composition of the plasma is a combination of gas and liquid which is superheated.

Plasma cutters often use compressed inert gasses and electricity in order to make a plasma. The electric circuit that is being made with the metal material, plasma cutters are able to cut through it. Touching the end of the nozzle with the metal will then create an electrical circuit. The fast flowing inert gasses will meet through the negative electrode with the sparks that is created by the electrical circuit. Plasma is transformed once the gases reach a temperature of more than 15,000 degrees Celsius. The plasma will then go out of the nozzle which will directly hit the metal that you are cutting. The plasma speeds up its exit because of the tiny opening on the tip. The reason for the accuracy of the plasma just like a laser is because of the speed, temperature, and it is focus.

Just as long as everything is set up properly, the cut will be almost like perfect. As long as the materials conduct electricity, the plasma cutter can cut it. These materials can be copper, stainless steel, aluminum and etc.

One of the main types of plasma cutter is the High-Frequency Contact. CNC operations are not capable of this kind of plasma cutter that is why it is called a low budget gear. Using a combination of high frequency and high voltage, these type can then create a plasma. Once the metal touches the torch, a plasma is then created.

The pilot arc type of plasma cutter is the one that produces two cycles of plasma. During the World War II, the first plasma cutters were born. It cuts metal through high frequency and high voltage circuits There is a very high risk of electrocution if the operator is not careful. It is also very hard to maintain and repair the first versions.

Regardless of the metals thickness, a plasma cutter can handle it. It the size of the machines that determines the sever cut. The sever cut is the thickness of the metal the plasma cutter can handle. The thicker the metal, the better the performance of a CNC plasma cutter .is. If you have a higher sever cut, the work may not be as precise. The edges must be cleaned once the cut is done. CNC plasma cutter are the once that are computer controlled that is why the cuts are more precise. A CNC cutter is very important if you have projects that are repetitive.
