Plasma Cutters: Facts You Need To Know
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.
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. Perhaps, many of us learned from our younger years that matter only consist of three states which are the solid, liquid and gas however, the matter of the fact is that there are actually four of them and the fourth one is plasma. Once again, if we are to define plasma, it is an ionized gas that is responsible for supplying sufficient amount of energy to free electrons that comes from atoms or molecules and, plasma is also the one who allows both 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. 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. If you are to look closely at its center, there you can find an electrode that is negatively charged. 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. The gas will continue to pass through the channels and the gas that has been passing through will be heated by the spark until it become plasma, the fourth state of matter. What makes plasma more incredible is that when it reach thirty thousand degree Fahrenheit, it is capable of cutting through almost anything.
There is also another of making plasma cutter works and that is by creating a high velocity of plasma flow between the electrode that is negatively charged and the electrode that is positively charged.
