How Do Plasma Cutters Actually Work?
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.
Before we proceed on discussing how plasma cutter works, lets us first define plasma, the one responsible for letting plasma cutter pass through thick materials, 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. 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. If the has is being boosted into an extremely high temperature, it will cause the energy to break the gas molecules apart and also, the atoms will start splitting. Apart from that, the fast moving electrons will also collide with the other electrons and ions thus releasing an enormous amount 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.
Plasma cutters actually works by sending an electric arc through a gas which is passing through a constricted opening. What you can find in the center of the channel is a negatively charged electrode. The circuit and the very powerful spark is the product of the connection that is being produced when a negatively charged electrode has been applied with power and the tip of the nozzle touched a positively charged metal. 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. 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.
