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. 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. 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 reason behind why plasma has an incredible cutting power is due to the enormous amount energy released from the collision.
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. 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. 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. Did you know that the temperature of plasma can actually reach an amazing thirty thousand degree Fahrenheit and that once it reached that level, it became capable of cutting almost any material.
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.
