How Plasma Cutters Work

By using a plasma torch, plasma cutters can cut metals. 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.

Plasma cutters often use compressed inert gasses and electricity in order to make a plasma. 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. The fast flowing inert gasses will meet through the negative electrode with the sparks that is created by the electrical circuit. The combination of the gas and the electricity will heat up that gas to up to 15,000 degrees Celsius and will then transform to a plasma. In order to cut the metal, touch the end of the nozzle to which the plasma goes out. 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.

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. 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. 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 higher the sever cut, the thicker the metal a plasma cutter can cut. A CNC plasma c cut will do a better work if the metal to be cut is thick. 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. When you have projects that are repetitive you better have a CNC plasma cutter.
