4 PLASMA CONSOLE PW30.
4.1 General remarks.
Console PW30 consists of a direct current power source built with inverter technology and designed to start the pilot
arc in a plasma welding system. The arc is struck with the aid of high-frequency (HF) high-voltage generated by the
internal circuits.
Two hydraulic circuits (Main and Aux) are connected to the power source to cool the torch. Two air circuits are also
connected to control plasma and shield gases.
Everything is managed by the console control, which communicates with the control of power source (21) by means of
a CAN bus serial line (CAN-1).
Console PW30 may be used only for the purposes described in this manual.
