The idea of plasma cutter was generated due to the need for better tools to cut and join aircraft parts during the Second World War. The cutter uses compressed gas and high voltage electrical arc to cut through different types of metals. The compressed gas is passed through a constricted opening. The temperature of the compressed gas is elevated when it is discharged through the opening which creates plasma- the fourth state of matter. When the compressed gas is passed through the opening in a high temperature, it cuts the molten metals into desired shapes. The molten area in the metal is blown off by the high temperature of the plasma.
These cutters are available in different sizes ranging from small cutters to large and more efficient cutters. There are small portable plasma cutters available in many of the online stores too. Hand-held cutters are used to cut through conductive metals with a thickness of half an inch. However, large cutters are used to cut through metals of 2 inch thicknesses in huge industries. Today these cutters are controlled by computers which are known as CNC cutting machines. The metals are arranged and cut with the help of cutting machines controlled directly by computers.
Benefits of Using Plasma Cutter
Portability: In the early days of its discovery, the plasma cutter was huge in size but today it is available in a range of sizes and shapes. Hand-held cutters and portable cutters can be easily bought from online stores at affordable price rates.
Precision: One of the greatest advantages of using these cutters is related to its impeccable precision and accuracy. Since most of these cutters are connected to CNC machines, it can be used to cut metals into desired shape quite easily.
Power consumption: In comparison to the other metal cutters, these cutters utilize less power. This is known to be another advantage of using these unique cutters.
Smooth edges: As these cutters give smooth edges after cutting metals and pipes; it is also used in a variety of other purposes such as fabrication of metals, artistic work on metals and so forth. It is also used to cut pipes as it gives smooth edges unlike the other manual cutters. The edges of the pipes are smooth which makes it easier to install.
Another great benefit of using these cutters involves the fact that the metal outside the cutting area remains cool even after the cutting process. This helps the metal to retain its paint and seldom causes warping which is quite common among other metal cutters. Plasma cutter can be bought online too at reasonable price rates for both industrial and domestic uses.
