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.
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, When we say plasma, it is a term that is commonly used in reference to the fourth states of matter, aside from solid, liquid, and gas, in which so many of the electrons are wandering around freely among the nuclei of the atom. 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. As what is being mentioned in the previous statement, a plasma define as an ionized gas in which sufficient energy is being provided to free electrons coming from atoms or molecules and also, it is the one that enables the coexistence of ions and electrons. 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.
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. 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. 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.
