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 equipment is a constant-voltage power source,
suitable for MIG/MAG and OPEN-ARC 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

IEC 60974-1 The welding machine is manufactured
IEC 60974-10 according to these international
standards.
Three-phase transformer-rectifier.
Flat characteristic.
Pict. 1
Suitable for continuous wire welding.
I2 max Unconventional welding current.
This value represents the max. limit
attainable in welding.
U0 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.
I2 Welding current
U2 Secondary voltage with welding current I2.
U1 Rated supply voltage
3~ 50/60Hz 50- or 60-Hz three-phase power supply.
I1 max Maximum absorbed current value.
I1 eff This is the maximum value of the actual
current absorbed, considering the duty cycle.
IP21C Protection rating for the housing.
Grade 1 as the second digit means that this
equipment is suitable for use outdoors in the
rain. The additional letter C means that the
equipment is protected against access to the
live parts of the power supply circuit by a tool
(diameter 2.5 mm).
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).

1.3 OVERLOAD CUT-OUT

This machine is protected by a thermostat, which prevents
the machine from operating if the allowable temperatures
are exceeded. In these conditions, the fan continues to
operate, the wire to flow and the led C lights.

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 cutout 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, wheels and the wire feeder unit support
(pict. 2).
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.
