Plasma Cutter

• A plasma cutter is a device that is very easy to manage and use. This is used to cut metals that conducts electricity and steels. The device works using an electric arc and gas, usually nitrogen, oxygen or an air, through a thin opening. This makes the gas temperature rise to the extent that it reaches the fourth state of matter which is the plasma. The gas that passes along the nozzle is being ionized by an interior electrode in which this produces an electrical arc. This arc creates strong plasma arc at the tip of the cutter.

• The elevated heat produces when the arc contact to the metal surface dissolves a portion not greater than 1.6mm in length. A good and nice cut is produce due to the plasma force which drives out the area that melts. The speeds while traveling the nozzle is 20000 fps and at the high temperature of 16, 000 Celsius. Small cutters are often comprised with a attached air compressor that uses 110 volts of electricity and an output of between 12-35 amperes.

• While the large cutters uses 220 volts of electricity and an output from about 50 to 80 amperes. Handy plasma cutter is used to cut up to half an inch thick of metal plates while the large plasma can but at least 5 centimeters of metal plates. The outer portion of the metal that is cut using the cutter retains it cool temperature which prevent it from deforming.

• The cutter is very much faster than tradition flame cutters. Some cutter can slice metal exactly and precisely. Plasma cutter has also a downside. The nozzle and the electrode need a regular replacement which is relatively expensive. The cutter cannot cut plastics and woods. And traditional torches are the best cutter for some thick metals.
