Plasma Cutters: Facts You Need To Know
The unique properties of plasma that is present in the plasma cutter is the one responsible for making such object pass through ferrous materials such as 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. When we were young, we learned about the states of matter and we are taught that there are juts three of them namely: solid, liquid and gas but the truth is that there are actually four states of matter and the fourth one on the list of 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 reason behind why plasma has an incredible cutting power is due to the enormous amount energy released from the collision.
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. What you can find in the center of the channel is a negatively charged electrode. When you put power to a negatively charged electrode and touch the tip of the nozzle with a positively charged metal, it will produce a connection and coming from that connection is the creation of a circuit and a powerful spark. 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.
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.
