Learn Everything There Is To Know About Plasma Cutters
With the advent of the unique properties of plasma, it makes it possible for plasma cutter to pass through the ferrous of all materials like metals and steels.
Prior to us continuing the discussion about plasma cutter and how it works, let us first define what plasma really is. 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. 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. You can actually get a plasma by boosting a gas to an extremely high temperature. 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. This process will also affect the electrons and ions as the fast moving electrons will collide with other electrons and ions causing it to release a tantamount of energy. The amazing cutting power of plasma is caused by the enormous amount of energy being released by the collision of electrons and ions.
Speaking of how a plasma cutter works, it actually works by sending a pressurized gas or an electric arc through a small channel or a constricted opening which is the cutting nozzle. 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. 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.
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.
