READ THIS MANUAL AND THE SAFETY RULES MANUAL
CAREFULLY BEFORE INSTALLING, USING, OR SERVICING
THE WELDING MACHINE, PAYING SPECIAL ATTENTION TO
SAFETY RULES. CONTACT YOUR DISTRIBUTOR IF YOU DO
NOT FULLY UNDERSTAND THESE INSTRUCTIONS.
This machine must be used for welding only.
It must not be used to defrost pipes.
It is also essential to pay special attention to the "SAFETY RULES"
Manual. The symbols next to certain paragraphs indicate points
requiring extra attention, practical advice or simple information.
This MANUAL and the "SAFETY RULES" MANUAL must be
stored carefully in a pica familiar to everyone involved in using the
machine.
They must be consulted whenever doubts arise and be kept for
the entire lifespan of the machine; they will also be used for
ordering replacement parts.
1 GENERAL DESCRIPTION
1.1 SPECIFICATIONS
This manual has been prepared for the purpose of educating
personnel assigned to install, operate and service the welding
machine.
This welding machine is a power source developed with inverter
technology, suitable for MIG.
The welding machines are supplied complete with wire feeder with
4-roller wire feeder. These devices can be used only for the
purposes stated in the manual.
Upon receiving the machine, make sure there are no broken or
damaged parts.
The purchaser should address any complaints for losses or
damage to the vector.
Please indicate the article and serial number whenever requesting
information about the welding machine.
1.2 EXPLANATION OF TECHNICAL SPECIFICATIONS

equipment.
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 a pollution rating of 3. (See IEC 60664).
2 INSTALLATION
• Only skilled personnel should install the machine.
• All connections must be carried out according to current
regulations, and in full observance of safety laws.
Make sure that the supply voltage corresponds to the value
indicated on the power cable. If it is not already fitted, connect a
plug suited to the power cable, making sure that the yellow/green
conductor is connected to the earth pin.
The capacity of the overload cut-out switch or fuses installed in
series with the power supply must be equivalent to the absorbed
current I1 max. of the machine.
2.1 PLACEMENT
Mount the handle. The handle must not be used for lifting the
welding machine.
Place the welding machine in a ventilated area.
Dust, dirt, and any other foreign matter entering the welding
machine can interfere with ventilation and thus with smooth
operation.
Therefore, in relation to the environment and working conditions,
it is important to keep the internal parts clean.
Clean using a jet of dry, clean air, being careful to avoid damaging
the machine in any way.
Before working inside the welding machine, make sure it is
unplugged from the power mains.
Any intervention carried out inside the welding machine must be
performed by qualified personnel.
2.2 PROTECTIONS
2.2.1 Block protection
In the event of a malfunction, the display screen B will show the
message WARNING to identify the type of fault.
If this message does not disappear when the machine is switched
off and back on, contact the after-sales service.
2.2.2 Overload cut-out
This appliance is protected by a thermostat that prevents machine
operation whenever acceptable temperatures are exceeded.
In these conditions, the fan continues to operate and the display
screen B shows the message WARNING tH in flashing mode.
3 DESCRIPTION OF POWER SOURCE (see pict. 1)
L - Earth lead or socket: where you must connect the earth cable
connector.
O - Switch: starts and stops the machine.
P - Mains cable.
R - Socket: connect the patch connector of the power source/wire
feeder connection power cable.
S - Connector: connect the connector of the power source/wire
feeder connection service cable.
4 DESCRIPTION OF THE WIRE FEEDER (see pict. 1)
A - Knob: selects and adjusts both the welding functions and
parameters.
B - Display screen: this displays both the welding parameters
and all the welding functions.
C - Centralized coupling: to which the welding torch must be
connected.
