Principle of plasma cutting Plasma cutting is a thermal cutting process in which a plasma arc is constricted through a nozzle. The transferred arc, which occurs when electricity flows from the non-melting electrode (cathode) to the workpiece (anode), is used to cut electrically conductive materials. This is the most commonly used form of plasma .

Plasma temporal evolution changes with pulse duration. For pulses longer than about 5ps, the laser-plasma interac-tions result in plasma heating and the plasma temperature increases with pulse duration [17].

The plasma arc cutting and gouging processes use this plasma to transfer an electrical arc to the workpiece. The metal to be cut or removed is melted by the heat of the arc and then blown away. While the goal of plasma arc cutting is the separation of the material, plasma arc gouging is used to remove metals to a controlled depth and width.

Cut Direction must be considered when programming the plasma cutter. Like a router, the direc-tion of travel the plasma torch takes will affect the cut quality. This is because the holes in the swirl ring produce a swirl in the plasma jet. The finish side of the plasma cut is the right side of the cut when facing the direction of travel.
