7.1 Plasma cutting process
The cutting action is performed when the plasma arc, made very hot and highly concentrated by the design of the torch, transfers
onto the conductive piece to be cut, closing the electrical circuit of the power source. The material is melted at the high temperature
of the arc, and then removed by the high pressure flow of the ionized gas from the nozzle.
The arc can have two different states: the transferred arc, when the current passes through the workpiece to be cut, and the pilot
arc or non-transferred arc, when this is established between the electrode and the nozzle.

* This equipment complies with EN/IEC 61000-3-12 if the maximum permissible mains impedance at the interface point to the public grid
(point of common coupling, PCC) is smaller than or equal to the Zmax stated value. If it is connected to a public low voltage system, it is
the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary, that the
equipment may be connected.
