How Plasma Cutters Work
You can cut metals using a plasma cutter that utilizes a plasma torch. In order for everything to work, a plasma must be created. Having a liquid and gas composition, you can create a plasma which is superheated.
In order to make a plasma cutter work, it uses compressed inert gases and electricity. In order to cut the metal, the plasma cutter creates an electric circuit with the metal being cut. Touching the end of the nozzle with the metal will then create an electrical circuit. The sparks will then travel through the negative electrode which will then meet with the fast flowing inert gasses. The high temperature of the gases reaching up to 15,000 degrees Celsius is the movement a plasma is created. The plasma will then go out of the nozzle which will directly hit the metal that you are cutting. The very reason for the fast exit of plasma on the tip of the nozzle is due to its tiny exit. The reason for the accuracy of the plasma just like a laser is because of the speed, temperature, and it is focus.
There will always be a perfect cut as long as everything is set up correctly. Since electricity is one of the main components of plasma, it can cut anything that also conducts electricity. Copper, stainless steel, and aluminum is just some of the materials that a plasma cutter can deal with.
A High-Frequency Contact is one of the main types of a plasma cutter. It is called a low budget equipment because it does not work with CNC operation. 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. The high frequency and high voltage circuits are the once used to cut metals. If the operator is not careful, there is a high risk of electrocution. The repair and maintenance of the old plasma cutter are very hard.
Regardless of the metals thickness, a plasma cutter can handle it. It the size of the machines that determines the sever cut. The the thickness of the cut a plasma cutter can handle will be determined by the sever cut. The thicker the metal, the better the performance of a CNC plasma cutter .is. It will have a messier cut if the sever cut is higher. Cleaning out the edges will be a must once the cut is done. The cuts are more precised in a CNC plasma cutter because it is computer controlled. When you have projects that are repetitive you better have a CNC plasma cutter.
