duration of the pilot arc based on the installed torch and the
selected processing procedure. It is nevertheless possible
to set this function on OFF, so as to be able to manually
adjust the pilot arc duration. Consumables last longer by
lowering the duration, but arc transfer complications may
occur. On the other hand, by raising the duration, it is
possible to transfer the arc more easily, but the
consumables will last less.
To exit the menu without making any selection, position the
cursor on the arrow on the bottom right and press knob S1
(Pict.1), to confirm exiting.
2.2.5 Automatic post gas adjustment (only for art.461)
By selecting this icon, it is possible to enter the menu
pertaining to automatic post gas duration adjustment.
The factory default mode is AUTO ON which allows the
power source to automatically and synergically adjust post
gas duration based on the mounted torch, the set current
value and the selected processing procedure. It is
nevertheless possible to set this function on OFF so as to
be able to manually adjust post gas duration (within certain
pre-set limits).
This can help when special, costly gases are used for
cutting, for which careful management of consumption can
lead to economic benefits.
To exit the menu without making any selection, position the
cursor on the arrow on the bottom right and press knob S1
(Pict.1), to confirm exiting.
2.2.6 Selecting the unit of measurement
By selecting this icon, it is possible to enter the menu
pertaining to unit of measurement adjustment
Here it is possible to select the icon relative to the units of
measurement and thereby choose from:
millimetres inches
bar and psi
The selected unit of measure remains highlighted until a
different one is chosen.
To exit the menu without making any selection, position the
cursor on the arrow on the bottom right and press knob S1
(Fig.1), to confirm exiting.
2.2.7 Selecting the outlet voltage divider for CNC
(optional for art.453)
.
By selecting this icon, it is possible to enter the menu to
select the CNC voltage divider.
The factory default mode is OFF meaning that there is no
voltage between outlet pins 5 (-) and 6 (+).
For use with CNC equipped with arc voltage control it is
possible to set this function on ON, so as to be able to
freely adjust the outlet divider values between a minimum
of 1/20V and a maximum of 1/100V. (ex. 1/20, 1/21, 1/22,
1/23, 1/24.....up to 1/100V).
This voltage is supplied between pins 5 (-) and 6 (+) of the
AMP connector located on the back of the power source
and is galvanically insulated from the cutting voltage.
To exit the menu without making any selection, position the
cursor on the arrow on the bottom right and press knob S1
(Pict.1), to confirm exiting.
2.2.8 Enabling current adjustment from CNC (optional
for art.453)
By selecting this icon it is possible to enter the menu
pertaining to enabling cutting current adjustment from CNC.
This function switches on and only affects cutting
current adjustment if the start function is ON from CNC
(par.2.1.7)
With the I CNC function enabled, the possibility of adjusting
the cutting current from the power source's front display
encoder is automatically disabled.
The factory default mode is OFF meaning that there is no
chance of adjusting the cutting current remotely between
pin 1 (0V) and pin 2 (10V).
If you wish to adjust the cutting current remotely (CNC),
you need to:
1) Place the Start function to On from the CNC
(par.2.1.7)
2) Place this function on ON and apply an
INSULATED VOLTAGE BETWEEN 0V AND 10V
between pin 1 (0V) and pin 2 (10V max) of the
AMP connector located on the back of the power
source.
The current value set from the CNC is ABSOLUTE,
therefore independent from the operating range of the
installed torch.
If the current requested by the CNC is greater than the
maximum allowed by the installed torch, the current will be
reduced to the lowest possible value for the installed torch
(see example 2).
EXAMPLES:
1) Torch ECF-181 cutting current 10-180A
Voltage between pins 1-2 = 5V
Remotely-adjusted current = 10+[(180-10)/10x
2) Torch ECF-71 cutting current 10-70A
Voltage between pins 1-2 = 5V
