Plasma Cutting Machine Working Principle

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.

Plasma cutting machine working principle.

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma typical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well plasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. 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. This increases the temperature and velocity of the plasma emanating from the nozzle. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.

Arc discharge heat forms working gas into the plasma state of high temperature. 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. What is plasma cutting.
