An air plasma cutting machine (tungsten inert gas,TIG) is a machine that melts and cuts metals with a high-temperature (about 20,000°C) arc plasma.
Since the high-temperature melted parts are blown away by high-pressure air, it is possible to cut stainless steel and many other metals (aluminum, brass, iron) that cannot be cut by gas cutting machines.
The main use of air plasma cutting machines is to cut thick metal plates. Because of the need to supply inert gas and high-capacity DC current, portability is somewhat limited, and the machines are generally used in processing plants.
It is used manually with a torch. Therefore, cutting is performed while blowing off the molten part, resulting in a large cutting allowance of several millimeters. Also, the cut surface is somewhat rough, so it is not suitable for finishing cutting.
In addition to processing in factories, plasma cutting machines are also used for cutting steel frames and steel materials at bridges and various construction sites.
Plasma cutting generates a plasma arc and melts the object to be cut with the arc heat and plasma flow.
Since the temperature around the plasma arc reaches 20,000°C or higher, some water injection types use cooling water in combination with the arc.
The following are advantages of plasma cutting.
