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. The composition of the plasma is a combination of gas and liquid which is superheated.
In order to make a plasma cutter work, it uses compressed inert gases and electricity. Using the metal that is being cut, a plasma cutter creates an electric circuit in order to cut the metal. In order for you to make an electric circuit, you have to touch the end of the nozzle with the metal. By using the negative electrode, the electrical sparks and the fast flowing inert gasses will meet. The high temperature of the gases reaching up to 15,000 degrees Celsius is the movement a plasma is created. In order to cut the metal, touch the end of the nozzle to which the plasma goes out. The plasma speeds up its exit because of the tiny opening on the tip. The speed, temperature, and the focus of the plasma are the reason why it cuts just like a laser.
The correct set up of your plasma cutter will make the perfect cut every time. The cutting ability of plasma cutters is more versatile just as long as the material also conducts electricity. A plasma cutter can work with a variety of materials including copper, stainless steel, aluminum and etc.
The High-Frequency Contact is one type of a plasma cutter. CNC operations are not capable of this kind of plasma cutter that is why it is called a low budget gear. High frequency and high voltage sparks are used in order to 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. The invention of the very first plasma cutters was in World War II. 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. Depending on the size of the machine is also the size of 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. 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. A CNC cutter is very important if you have projects that are repetitive.
