2 - SYSTEM DESCRIPTION

2.1 - Introduction.

The Plasma PROF 164 HQC is a system for cutting electrically conductive materials using a
multigas plasma arc process, for mechanical systems.
It consists of an electronic Power Source (art. 954), a Starter Unit HV18 (art. 472), a Gas
Console PGC1-2 (art. 477), a PVC Valve Console (art. 478), the Torch CP250G (art. 1236), and
a series of accessories to adapt to automated systems (see list in the Sales Catalogue).
The units that make up the cutting system and the corresponding connections can be seen in
fig. 2.1.1.

2.1.1 - Plasma PROF 164 HQC system.

2.2 - Technical specifications.

To verify the technical specifications, see the machine plate on the equipment, the Instruction
Manual, and Sales Catalogue.

2.3 - Description of Plasma PROF 164 HQC system.

The cutting system is controlled by microprocessor-based circuits, which manage the
functions for the plasma arc control and the interface with the operator and system.
Referring to fig. 2.1.1, electrical diagrams in par. 5, the drawings and tables in par. 4 you may
identify the main blocks that make up the system.
Power Source and Gas Console contain the microprocessor-based circuits, which in addition
to managing the functions of the groups that make up the system, communicate amongst
themselves by CAN bus serial line, to collaborate smoothly with system operation.
Based on this architecture, one may identify the following units:
− MASTER microprocessor, in the control board (38) of the Power Source art. 954;
− SLAVE microprocessor, in the panel board (20) of the Gas Console art. 477.
Each microprocessor is programmed with a different program, which obviously must be
compatible with that of the other microprocessor. To make it easier to insert and update these
programs, a unique access system is present (the connector (34) (J) on the front panel of the
Power Source for RS232 serial communication), which allows both microprocessors to be
programmed in a single session.
