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
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
IEC60974.1 The welding
IEC60974.10 according
standards.
Cl. A Machine for professional and industrial use.
S ing le-phase transformer – rectifier.
Three-phase transformer-rectifier.
Flat characteristic.
Suitable for continuous electrode welding.
I max Unconventional welding current. This value

IP21 Protection rating for the housing.
Grade 1 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 664).
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 and
the lamp A 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 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 (pict. 1, 2 and 5)
Mount the handle, rear wheels. 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.
To make firm the cylinder on the back of the machine, mount
the M8x16 screw and the corresponding box nut supplied with
the equipment as shown in picture 5.
2.2. INTERNAL CONNECTIONS
• Any intervention carried out inside the welding machine
must be performed by qualified personnel.
• Before working inside the welding machine, make sure
that the plug is disconnected from the power mains.
• After final inspection, the welding machine is connected
to the voltage indicated on the power supply cable.
• To change the supply voltage, remove the right side
panel and arrange the voltage change terminal board
connections as shown in the picture.
