Remotely-adjusted current = 10 + [(180-10)/10x
which will automatically be lowered to 70A by the
power source since the installed torch cannot operate
above that.
To exit the menu after setting the necessary values or
without any setting, position the cursor on the arrow on the
bottom right and press the encoder to confirm exiting.
2.2.9 Limitation of the absorbed input power
By selecting this icon, it is possible to enter the menu
pertaining to the limitation of the absorbed input power.
The factory default mode is OFF meaning that there is no
limitation to the absorbed input power.
If necessary, however, by placing this function on ON, it is
possible to select the maximum value of absorbed power to
adapt the power source to the system to which it will be
connected. Accordingly it will be possible to connect it
easily to any industrial system avoiding overloading or
tripping the relative protections.
You will only need to set the available power value and the
machine will duly adjust all of the cutting parameters,
offering the highest possible cutting current.
To exit the menu after setting the necessary values or
without any setting, position the cursor on the arrow on the
bottom right and press the encoder to confirm exiting.
2.3 FAN MANAGEMENT
Fan management is fully automatic.
The power source constantly monitors the temperature of
the internal parts and duly manages fan rotation speed.
Speed increases as the internal temperature increases,
and vice versa.
When the power source remains unused and the
temperature of the internal parts normalises, the fan stops
completely.
2.4 AUTOMATIC CUTTING OK TO MOVE (optional for
art.453)
When the power source is used in combination with an
automatic cutting system requiring consent for torch
movement, it is possible to use the transferred arc
command.
In fact, the machine provides a dry NO contact (relay)
which only closes after arc transfer (Pict.4 Ref.D), between
pins 12 and 14 of the AMP connector located on the back
of the power source.
2.5 POWER SOURCE MEMORY
The power source memorises the entered settings and the
last cutting condition to be used, accordingly when the
power supply is cut off and switched back on again, it
displays the last work conditions
2.6 POWER SUPPLY VOLTAGES
The power source is equipped with an auto-adjustment
system that allows it to work without any changes, at
5
] = 95A
different three-phase voltages, namely 208V-220V-230V-
400V-440V ± 10%. When the power source is switched on
it detects the type, the quality and the presence of the three
phases and automatically adjusts for optimal operation.
3. CUTTING PROBLEMS
3.1. INSUFFICIENT PENETRATION
This error may be caused by the following:

high speed. Always make sure that the arc fully
penetrates the workpiece and is never held at a
forward angle of more than 10 - 15°. This will avoid
incorrect consumption of the nozzle and burns to the
nozzle holder.

Excessively thick workpiece.

Grounding clamp not in good electrical contact with
the workpiece.

Worn nozzle and electrode.

Cutting current too low.
NOTE: When the arc does not penetrate, the molten metal
scraps obstruct the nozzle.
3.2. THE CUTTING ARC GOES OFF
This error may be caused by:
• worn nozzle, electrode or swirl ring,
• air pressure too high,
• supply voltage too low.
3.3. SLANTED CUT
If the cut appears slanted, turn the machine off and replace
the nozzle.
When the cutting current is above 45 A, prevent the nozzle
from coming into electrical contact with the workpiece
(even through scraps of molten metal), this condition
causes rapid and at times instantaneous destruction of the
nozzle hole, leading to poor quality cutting.
3.4. EXCESSIVE WEAR ON CONSUMABLE PARTS
This problem may be caused by:
a) air pressure too low compared to the recommended
level.
b) excessive burns on the end of the nozzle holder.
c) Pierce through distance between torch and sheet too
short.
d) One or more of the parts mounted in the torch are not
e) There are impurities (water, oil or other) in the supply
gas.

4. HELPFUL HINTS


If the system air contains considerable amounts of
moisture and oil, it is best to use a drying filter to avoid
excessive oxidation and wear on consumer parts,
damage to the torch and a reduction in the speed and
quality of the cutting.

The impurities in the air encourage oxidation of the
electrode and nozzle, and may make it difficult to
strike the pilot arc. If this occurs, use fine sandpaper
to clean the end of the electrode and the interior of the
nozzle.

If the quality of the gas supply is not good, the cutting
speed drops, cutting quality decreases and the service
life of the consumables decreases.

Make sure that the new electrode and nozzle to be
mounted are thoroughly clean and degreased.
