Learn Everything There Is To Know About Plasma Cutters
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.
Prior to us continuing the discussion about plasma cutter and how it works, let us first define what plasma really is. Plasma, defined by wikipedia, is one of the four fundamental states of matter (other being the solid, liquid and gas) and is also known as an ionized gas which consists of positive ions and free electrons in proportions that results in more or less no overall electric charge, typically at low pressures (can be observed in the upper atmosphere and with fluorescent lamps) or at very high temperatures (like the stars and nuclear fusion reactors). 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. To simply put, a plasma is an ionized gas that provides sufficient amount of energy to free electrons coming from the atoms or the molecules plus, it is also the one responsible for letting both the ions and electrons to coexist. If you are curious as to how plasma are made, you can try boosting a gas to an extremely high temperature and you will get plasma. When the gas was boosted on to an extremely high temperature, the energy begins to break the gas molecules apart and the atoms will also begin to split as well. 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.
Plasma cutters actually works by sending an electric arc through a gas which is passing through a constricted opening. You can find in the middle of the channel a negatively charged electrode. Once you apply any power to the negatively charged electrode, and you touched the tip of the nozzle to a positively charged metal, what will happen is that a connection will be made and it creates a circuit and a very powerful spark as well. Plasma will be produced once the has that has been passing through the channel will be heated by the spark until it reach its fourth state form, so to speak. What makes plasma more incredible is that when it reach thirty thousand degree Fahrenheit, it is capable of cutting through almost anything.
Other than the things being stated previously, another way that plasma cutter can work is by creating a high velocity plasma flow coming the negatively charged electrode and the positively charged one.
