4.2.1 Preparation and execution of the CUT

After starting the system by means of the switch on the
front power source panel, the lighting up of the CUT
LED B (see Fig. 21) indicates that the machine is in "cut"
mode. First of all, a series of selections/adjustments must
be made and a check must be carried out to ensure the
RUN key is not pressed (PREFLOW and CUTFLOW dis-
play screen in Fig.21 of PLASMA and SECONDARY gas
flow off).
The first thing to do, in sequence, is the selection indicat-
ed on table 1.

By keeping the current selection button pressed (LED I
on), end mode is selected as indicated by the flashing
LED. The current can now be regulated, with 1A step,
in preset intervals [20-30 A] , [40-50 A], [70-90A], [110-
120A], [180-200 A], [230-250 A].
The second thing to do, in sequence, is the regulation in-
dicated on table 2.
When the SET key is pressed, the gas flow for each chan-
nel is active for 10 s: after which, the key must be pressed
again to continue regulation.
By pressing the SET button again after the last adjust-
ment, the regulation mode is exited. If the button is
pressed again, return is made to the first regulation, and
so on.
The arrow LEDs under the display screen of the corre-
sponding channel indicate the direction of adjustment
of the knob: if the left one is lit, flow must be increased
(clockwise), vice versa for the right one (anticlockwise).
Once the correct flow is achieved, depending on the se-
lection made on Tab. 1, both are switched on.
After exiting from regulation mode, after the above adjust-
ments, press the RUN button: all the display screens will
thus light up relating to the PLASMA and SECONDARY
channels, and the power source will be ready for cutting.
If the H35 or F5 gas has been selected, the LED comes on
of the PGC-2 gas console.
