1 GENERAL DESCRIPTIONS

1.1 Specifications
This equipment is a power source developed using
INVERTER technology, suitable for MIG/MAG and
OPEN-ARC welding.
1.2 Explanation of technical specifications
Art. Item number, which must be indicated on
any type of request regarding the welding
machine
n°. Serial number, which must be indicated
on any type of request regarding the
welding machine.
Single-phase static transformer-rectifier
frequency converter.
Suitable for continuous electrode
(MIG/MAG) welding.
AMP Unconventional welding current.
The values represent the minimum and
maximum levels attainable in welding.
Uo Secondary open-circuit voltage (peak V)
X Duty cycle percentage.
The duty cycle expresses the percentage
of 10 minutes during which the machine
may run at a certain current without
overheating.

IP23 Protection rating for the housing.
Grade 3 as the second digit means that
this equipment is suitable for use
outdoors in the rain.
Suitable for use in high-risk
environments.
NOTES: The welding machine has also been
designed for use in environments with pollution
rating of 3. (See IEC 664).
1.3 Protections
1.3.1 Block protection
In the event of a malfunction, a number with the
following meaning may appear on the display G:
52 = Start button pressed during start-up.
53 = start button pressed during thermostat reset.
56 = Extended short-circuit between the welding
electrode and the material to be welded.
Shut the machine off and turn it back on.
If different numbers appear on the display, contact
technical service.
1.3.2 Mechanical protection (safety button)
When the movable side is opened, this activates
the safety button that prevents operation of the
welding machine. This protection, indicated when
the LED A is lit, avoids hazardous situations when
the operator replaces the roller of the wire feeder
unit or the welding electrode.
1.3.3 Thermal protection
This machine is protected by a thermostat, which
prevents the machine from operating if the
allowable temperatures are exceeded. Under these
conditions the fan keeps running and the LED A
lights.
2 INSTALLATION
Make sure that the supply voltage matches the
voltage indicated on the specification plate of the
welding machine.
Mounting a plug with an adequate capacity for the
supply cable, making sure that the yellow/green
conductor is connected to the earth pin.
The capacity of the overload cutout switch or fuses
installed in series with the power supply must be
equivalent to the absorbed current I
machine.
2.1 Setup
Skilled personnel must install the machine. All
2
connections must be carried out according to
current regulations, and in full observance of safety
laws (regulation CEI 26-10 - CENELEC HD 427).
WARNING: This equipment does not comply with
IEC 61000-3-12. If it is connected to a public low
voltage system, it is the responsibility of the installer
or user of the equipment to ensure, by consultation
