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.
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. 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. 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 amazing cutting power of plasma is caused by the enormous amount of energy being released by the collision of electrons and ions.
The plasma cutter actually works by sending a pressurized gas through the small channel in the cutting nozzle. 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. 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.
