Plasma Cutters: Facts You Need To Know
A plasma cutter is an object that can pass through even the ferrous of materials like metals and steel and that is because of the contribution of the unique properties of plasma.
Let us first define plasma before we continue discussing about plasma cutters and how it works. Speaking of plasma, it is known to be as the fourth state of matter apart from solid, liquid and gas and is also known as a hot ionized gas which consists of approximately the same equal numbers of positively charged ions and the negatively charged electrons. Before, many schools teach about the state of matter having only three which are the solid, liquid and gas but the truth is that, there really is four of them and the fourth one being the plasma. As what is being mentioned in the previous statement, a plasma define as an ionized gas in which sufficient energy is being provided to free electrons coming from atoms or molecules and also, it is the one that enables the coexistence of ions and electrons. By boosting a gas to an extremely high temperature will definitely result from the creation of plasma. By doing so, the energy will start to break apart the gas molecules and the atoms will begin to split as wel;. With this, the fast moving electrons will also collide with the other electrons and ions which will lead to the release of an enormous amount of energy. The enormous amount of energy being released by the collision is the reason why plasma has an unbelievable cutting power.
The plasma cutter actually works by sending a pressurized gas through the small channel in the cutting nozzle. What you can find in the center of the channel is a negatively charged electrode. The circuit and the very powerful spark is the product of the connection that is being produced when a negatively charged electrode has been applied with power and the tip of the nozzle touched a positively charged metal. As the gas continue to pass through the channels, the spark will heat the gas until it reached the fourth state of matter which is known to us as plasma. Once the temperature of plasma reached an amazing level of thirty thousand degree Fahrenheit, it became capable of cutting through almost anything, even metals and steels.
Aside from the ones being mentioned above, plasma cutter can also work by creating a high velocity plasma flow between the negatively charged electrode and the positively charged one.
