Plasma Cutting Machine Working Principle

The plasma arc cutting process is illustrated in fig.

Plasma cutting machine working principle.

Principles of plasma cutting. A processing method which takes oxygen or nitrogen as working gas make use of high temperature plasma arc heat to melt and evaporate the incision of the metal part and by means of the momentum of high speed plasma flow to remove the molten metal in order to form slotting seam. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel. The plasma arc formation begins when a gas such as oxygen nitrogen argon or even shop air is forced through a small nozzle orifice inside the torch.

This is a cutting system utilizing heat generated by arc discharge between the cutting object material and the electrode inside the torch. This increases the temperature and velocity of the plasma emanating from the nozzle. Working principle of the plasma cutting machine. Arc discharge heat forms working gas into the plasma state of high temperature.

The plasma jet of high temperature and high speed is blown out from the.
