A Closer Look At Plasma Cutters

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. In order to create a plasma, you need to have a combination of gas and liquid which is super-heated.

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. It is through touching the end of the nozzle with the metal that sparks are being created creating a circuit. By using the negative electrode, the electrical sparks and the fast flowing inert gasses will meet. 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 very reason for the fast exit of plasma on the tip of the nozzle is due to its tiny exit. Just like a laser, the plasma cuts perfectly because of its speed, temperature and focus.

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. These materials can be copper, stainless steel, aluminum and etc.

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. High frequency and high voltage sparks are used in order to 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. There will be a high risk of electrocution if the operator is not really careful. The repair and maintenance of the old plasma cutter are very hard.

Different thickness of metals is no problem for a plasma cutter. 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. If you have a higher sever cut, the work may not be as precise. 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.
