INSTRUCTION MANUAL FOR WIRE WELDING MACHINE
IMPORTANT
READ THIS MANUAL AND THE SAFETY RULES MANUAL
CAREFULLY
BEFORE
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 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.

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 F 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 and the rear and front 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.
