The plasma cutting process includes the consumption of a plasma torch to cut metals and steel of different thickness. Plasma cutters have become very popular in the world as an excellent tool for metal cutting. This wide popularity has resulted in various manufacturers conducting extensive research to enhance the functionality of the plasma cutters. Hypertherm plasma cutters is the results of this research, and includes all the characteristics of an advanced plasma cutting device. home machining and tooling.
Scientists have proved that aside from the three states of matter which are known to them, namely solid, gas, and liquid, there is a fourth type known as plasma. It doesn’t exist naturally on earth. When a gas is heated to very high temperature, tremendous amount of energy is moved to the atoms which ionize into its basic components, nuclei and electrons. Plasma is known to be an excellent electric conductor.
Adding to this discussion.
Plasma cutters work by passing a gas through a narrow opening and bringing this in contact with an electric arc. The gas used can be nitrogen, oxygen, compressed, or argon air. This causes the temperature of the gas to rise astronomically resulting in the manufacture of plasma. This high energy released is passed to the metal under operation by the electrical conductivity property of plasma. Since the plasma is essentially a fluid, it has the potential to clear the metal surface free of the residue produced from the cut.
The main drawback of conventional gas cutters were that they weren’t able to cut metals with good conductivity. This disadvantage has been overcome with the new plasma cutter. The cutter can be used in order to cut mild steel, aluminum, copper, cast iron, and stainless steel. Therefore they it is widely employed in industries where such operations are involved.
The new plasma cutters are relatively cheaper than conventional gas cutters which gives them preference over the older type of cutters. They have the advantage of being user friendly and ensure economic advantages like minimized energy consumption. Since they don’t require flammable constituents, the risk factor involved is much lesser. They can be operated on electric power or gas. There are cases where Nitrogen or highly pressurized air can be used.
Plasma cutters are considered to be more effective than traditional oxy fuel cutters because they complement the work quickly and efficiently. Plasma cutters generate heat which is about 22000 degrees whereas the oxy fuels generate a mere 3150 degree Celsius. They can easily burn through most surface coatings such as paint and rust and still impart excellent cutting results.
Easy on the pocket, plasma cutters are more economical. Plasma cutting costs are about half than that of the oxy fuel.
It is important to have an idea how thick the metal is that you are going to cut with the equipment. The thickness of the metal will play a direct affect on the extent of the equipment required. For operations where cutting thin metals are involved, a smaller machine will be sufficient whereas to cut thick metals, heavier equipment is required.
