INSTRUCTION MANUAL FOR WIRE WELDING MACHINE
IMPORTANT: BEFORE STARTING THE EQUIPMENT,
READ THE CONTENTS OF THIS MANUAL, WHICH MUST
BE STORED IN A PLACE FAMILIAR TO ALL USERS FOR
THE ENTIRE OPERATIVE LIFE-SPAN OF THE MACHINE.
THIS EQUIPMENT MUST BE USED SOLELY FOR WELD-
ING OPERATIONS.
FOR THE DIMENSIONS AND WEIGHT OF THIS WELDING
MACHINE, SEE THE SPECIFIC CATALOGUE.
1 SAFETY PRECAUTIONS
WELDING AND ARC CUTTING CAN BE HARMFUL TO
YOURSELF AND OTHERS. The user must therefore be edu-
cated against the hazards, summarized below, deriving from
welding operations. For more detailed information, order the
manual code 3.300.758
ELECTRIC SHOCK - May be fatal.
· Install and earth the welding machine according to
the applicable regulations.
· Do not touch live electrical parts or electrodes with
bare skin, gloves or wet clothing.
· Isolate yourselves from both the earth and the workpiece.
· Make sure your working position is safe.
FUMES AND GASES - May be hazardous to your health.
· Keep your head away from fumes.
· Work in the presence of adequate ventilation, and
use ventilators around the arc to prevent gases from
forming in the work area.
ARC RAYS - May injure the eyes and burn the skin.
· Protect your eyes with welding masks fitted with fil-
tered lenses, and protect your body with appropriate
safety garments.
· Protect others by installing adequate shields or curtains.
RISK OF FIRE AND BURNS
· Sparks (sprays) may cause fires and burn the skin;
you should therefore make sure there are no flam-
mable materials in the area, and wear appropriate
protective garments.
NOISE
This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding proce-
dure may produce noise levels beyond said limit;
users must therefore implement all precautions required by
law.
PACEMAKERS
· The magnetic fields created by high currents may affect the
operation of pacemakers. Wearers of vital electronic equip-
ment (pacemakers) should consult their physician before
beginning any arc welding, cutting, gouging or spot welding
operations.
EXPLOSIONS
· Do not weld in the vicinity of containers under pres-
sure, or in the presence of explosive dust, gases or
fumes. · All cylinders and pressure regulators used in
welding operations should be handled with care.

ELECTROMAGNETIC COMPATIBILITY
This machine is manufactured in compliance with the
instructions contained in the harmonized standard EN50199,
and must be used solely for professional purposes in an
industrial environment. There may be potential difficul-
ties in ensuring electromagnetic compatibility in non-
industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
2 GENERAL DESCRIPTION
2.1 SPECIFICATIONS
This manual has been prepared for the purpose of edu-
cating personnel assigned to install, operate and service
the welding machine.
This equipment is a constant-voltage power source, suit-
able for MIG/MAG and OPEN-ARC welding.
Upon receiving the machine, make sure there are no bro-
ken or damaged parts.
The purchaser should address any complaints for
losses or damage to the vector. Please indicate the

mation about the welding machine.

2.2 EXPLANATION OF TECHNICAL SPECIFICATIONS

EN 50199 The welding machine is manufactured
EN60974.1 according to these international stan-
dards.
N° serial number, which must always be
indi- cated on any type of request regarding
the welding machine.
three-phase transformer-rectifier.
Flat characteristic.
MIG/MAG. Suitable for continuous electrode 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 out-
doors 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).
