INSTRUCTION MANUAL FOR WIRE WELDING MACHINE
IMPORTANT
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, TIG and MMA welding.
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
IEC60974-1 The welding machine is manufactured
IEC60974-10 according to these international standards.
Cl. A
Machine for
professional and industrial
use.
Single-phase static transformer-rectifier
frequency converter.
MIG
Suitable for MIG-MAG welding.
MMA
Suitable for welding with covered electrodes.
TIG
Suitable for TIG welding.
U
0
Secondary open-circuit voltage.
X
Duty cycle percentage. The duty cycle
expresses the percentage of 10 minutes
during which the welding machine may run at
a certain current without overheating.

This is the maximum value of the actual
current absorbed, considering the duty cycle.
This value usually corresponds to the capacity
of the fuse (delayed type) to be used as a
protection for the 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
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 case of malfunction, the display A shows information about
the error and indications on how to solve it.
2.2.2 Overload cut-out
This machine is protected by two thermostats, which prevent
the machine from operating if the allowable temperatures are
exceeded. In these conditions the fan continues to operate
and the display A shows the message: Thermal protection n.1
or Thermal protection n.2.
2.3 PASSWORD
This device is protected against use by unauthorized
personnel through the possibility of activating a password
request upon start-up. The machine is supplied with this
function disabled.
To activate it, enter the submenu using the knob B and select
Password, then select the ON position, using the same knob,
and press on it.
