Jun 25, 2019 · Plasma cutting emerged from plasma welding in the1960s and developed into a very productive process for cutting sheet metal and plates in the 1980s. Compared to traditional “metal vs. metal” cutting, plasma cutting does not produce metal chips and offers precise cuts. The early plasma cutters were large, slow and expensive.
As with other machine tools, CNC (Computer Numerical Control) technology was used in the plasma cutter from the late 1980s to the 1990s. Thanks to CNC technology, plasma cutters were given greater flexibility in cutting different shapes based on a series of various instructions programmed into the numerical control of the machine.

Plasma arc cutting is a great process for cutting mild steel plate, offering much higher speeds than oxy-fuel cutting, but sacing some edge quality. That is where plasma is tricky. Edge quality has a sweet spot that, depending on cutting current, generally ranges from about 1/4 inch up to 1.5 inches.
Hand torches can usually cut up to 38 mm thick steel sheet, stronger computer controlled torches can cut up to 150 mm thick steel sheet. Since plasma cutters produce a very hot and very localised “cone” for cutting, they are very useful for cutting and welding sheets in curved or angled shapes.
All wiring of the system should be confirmed before power. When using plasma cutting machine, the steel plate must be leveled, which can not have large fluctuations, otherwise, it will affect the cutting size accuracy and greatly reduce the service life of the nozzle and electrode. 7. Troubleshooting

Plasma cutting machine is a new type of hot cutting equipment, its working principle is based on the compressed air as working gas, high temperature and high speed of plasma arc as heat source, molten metal will be partially melted, and at the same time high-speed air blow away the molten metal, and form the narrow cut seam.
Technique of Cutting: The surface of the metal to be cut should be free of grease, oil and rust and the heating flame held above the edge of the metal to be cut. The metal is brought to white heat and then the cutting valve is released. The cut then proceeds with a steady rate. The cut usually starts at one of the edges of the plate.
