Plasma cutting machine, the working gas that can be used (working gas is the conductive medium of the plasma arc, and it is also a heat carrier, while also excluding the molten metal in the cut), the plasma arc cutting characteristics, cutting quality, speed are obvious influences. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor, and some mixed gases.

Plasma cutting machines are used to cut thin metal sheets, square and round metal pipes, including iron, cold rolled steel, hot rolled steel, stainless steel, galvanized steel, carbon steel, copper, brass, alloys, bronze, aluminum, titanium. Plasma cutting machines are widely used in machine tool manufacturing, petrochemical equipment, light industry machinery, pressure vessels, shipbuilding, mining machinery, electricity, bridge construction, aerospace, steel structure and other industries, suitable for amateurs, family workshops, family business, Small workshops, small workshops and other industries, business, school education, industrial manufacturing.
