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
EN 50199 The welding machine is manufactured
EN60974.1
according to these international
standards.
Single-phase transformer - rectifier
Three-phase
transformer-rectifier.
Flat characteristic.
Suitable for continuous electrode welding.

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.

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
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)
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.
