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.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.

1.3 DESCRIPTION OF PROTECTION
This unit is protected by a normally closed thermostat
placed on the power transformer. When the thermostat
intervenes, the machine stops welding, while the motor-
driven fan continues to work. Wait a few minutes to allow
the generator to cool down.
2 INSTALLATION
2.1 PRECAUTIONS
Carefully read all the instructions about the installation of
the machine.
WARNING : ELECTRIC SHOCK CAN KILL!
•
This machine must be installed by skilled personnel.
Make sure that the input power plug has been disconnected
before inspecting, repairing, or servicing.
•
Connect the yellow-green wire to a good electrical
ground.
2.2 SET UP
Unpack the machine and place it in a properly ventilated
area, possibly not dusty, making sure that airflow on the
cooling vents is not obstructed.
WARNING: RESTRICTED AIRFLOW causes overheating
and possible damage to internal parts.
•
Maintain at least 20 inches (500 mm) of free space on
all sides of the unit.
•
Do not place any filtering device over the intake air
vents of this power source.
• The warranty is void if any type of filtering device is
used.
2.3 START UP
This unit must be installed by skilled personnel. All fittings
must be in conformity with the existing safety standards.
See CEI standards 26-10 -CENELEC HD 427.
2.3.1 Preparation
•
Install the components supplied with the welding
machine (pict.5).
•
Connect the welding torch (36).
•
Check that the wire diameter corresponds to that shown
on the drive roll and mount the wire spool.
• Make sure that the wire goes into the groove of the drive
roll (B, fig.4).
•
Before connecting the power supply cable (34) ensure
that mains voltage corresponds to the machine voltage and
that the earth plug is efficient.
•
(Fig. 1) The connection voltage can be changed on the
60% at I =100 A. This means that the
2
welding machine can weld with a current
I =100A for 6 minutes out of 10, i.e. 60%.
2

Grade of protection of the case.
Grade 1 as a second digit means that this
unit is not fit for working in the rain.
