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 WEL-
DING OPERATIONS.
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 appropria-
te 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 excee-
ding 80dB. The plasma cutting/welding procedure
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 pur-
poses in an industrial environment. There may be poten-
tial difficulties in ensuring electromagnetic compatibility
in non-industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
2 GENERAL TECHNICAL DESCRIPTIONS
2.1 SPECIFICATIONS
This manual has been prepared with the intent of instructing
the operator on how to install, operate, and properly main-
tain this electric arc welding machine.
This machine is a constant voltage power source for
MIG/MAG and OPEN-ARC welding.
Upon receiving and unpacking the machine, make a careful
inspection to ensure that there are no damaged parts.
Should there be a claim for losses or damages it must be
made by the purchaser directly to the shipper who hand-
led the goods.
When requesting information about this welding machi-
ne please state the machine's part number and serial
number to ensure receiving accurate information rela-
ting to your machine.
2.2 DESCRIPTION OF TECHNICAL SPECIFICATIONS
EC 974.1. This machine is manufactured according to the
EN 60947.1 IEC 974 international standard.
N°. Machine Serial Number which must appear on
requests or inquiries concerning the machine.
Three phase transformer-rectifier.
Flat characteristic.
MIG/MAG. Continuous wire welding
U0. Secondary no-load voltage
X. Duty-Cycle Percentage
The duty-cycle is the number of minutes the
machine can operate (arc on) within a ten
minute period without overheating. The duty
cycle varies according to the output current.
I2. Output welding current
U2. Secondary voltage whith welding current I2
U1. Nominal supply voltage
3~50/60Hz Three-phase input supply at 50 or 60 Hz
I1. Input Amps absorbed corresponding to diffe
rent output levels (I2).
IP21. Protection class of the machine's case
The 1 in the singles digit place means that this
unit is not fit to work outdoors in the rain.
S
Fit to work in hazardous areas.
NOTE: This machine has also been designed to work
in class 3 pollution areas (see IEC 664)
3 INSTALLATION
3.1 SETUP
Place the machine in a ventilated area.
Dust, dirt, or any other foreign material that might enter the
machine may restrict the ventilation which could affect the
