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.

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. By doing so, the energy will start to break apart the gas molecules and the atoms will begin to split as wel;. 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.

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. 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. 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.

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.
