A Closer Look At Plasma Cutters
Plasma cuter work by cutting metal using a plasma torch. You have to create a plasma in order for a plasma cutter to work. Having a liquid and gas composition, you can create a plasma which is superheated.
The combination of compressed inert gasses and electricity are commonly used by plasma cutters. The electric circuit that is being made with the metal material, plasma cutters are able to cut through it. In order for you to make an electric circuit, you have to touch the end of the nozzle with the metal. The sparks will then travel through the negative electrode which will then meet with the fast flowing inert gasses. 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 small exit on the tip of the nozzle is the very reason the plasma speeds up its 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. As long as the materials conduct electricity, the plasma cutter can cut it. Copper, stainless steel, and aluminum is just some of the materials that a plasma cutter can deal with.
The High-Frequency Contact is one type of a plasma cutter. It is considered as a low budget gear as it is not compatible with CNC plasma cutting operations. Using a combination of high frequency and high voltage, these type can then create a plasma. In order for it to create a plasma, the tip f the torch should touch the metal.
Plasma are produced in two cycles in a pilot arc type. It is during the World War II that the first plasma cutters were invented. The high frequency and high voltage circuits are the once used to cut metals. There is a very high risk of electrocution if the operator is not careful. The repair and maintenance of the old plasma cutter are very hard.
A plasma cutter can cut metals regardless of its thickness. 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 thickness of the metal is what determines the easiness of the job will be for a CNC plasma cutter. But the thicker the sever cut, the messier the cut will be. Once the cut is done, you still have to clean out the edges. Because it is computer controlled the cut of a CNC plasma cutter is more precise. When you have projects that are repetitive you better have a CNC plasma cutter.
