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 US-
ERS FOR THE ENTIRE OPERATIVE LIFE-SPAN OF THE
MACHINE. THIS EQUIPMENT MUST BE USED SOLELY
FOR WELDING OPERATIONS.

1 SAFETY PRECAUTIONS

WELDING AND ARC CUTTING CAN BE HARM-
FUL TO YOURSELF AND OTHERS. The user
must therefore be educated against the hazards, summa-
rized below, deriving from welding operations. For more
detailed information, order the manual code 3.300.758
ELECTRIC AND MAGNETIC FIELDS - May be dangerous.
• Electric current following through any con-
ductor causes localized Electric and Magnetic
Fields (EMF). Welding/cutting current creates
EMF fields around cables and power sources.
• The magnetic fields created by high currents may affect
the operation of pacemakers. Wearers of vital electronic
equipment (pacemakers) shall consult their physician be-
fore beginning any arc welding, cutting, gouging or spot
welding operations.
• Exposure to EMF fields in welding/cutting may have
other health effects which are now not known.
• All operators should use the followingprocedures in or-
der to minimize exposure to EMF fields from the welding/
cutting circuit:
- Route the electrode and work cables together
- Secure them with tape when possible.
- Never coil the electrode/torch lead around your body.
- Do not place your body between the electrode/torch
lead and work cables. If the electrode/torch lead
cable is on your right side, the work cable should also
be on your right side.
- Connect the work cable to the workpiece as close as
possible to the area being welded/cut.
- Do not work next to welding/cutting power source.
EXPLOSIONS
• Do not weld in the vicinity of containers under
pressure, or in the presence of explosive dust, gas-
es or fumes.
• All cylinders and pressure regulators used in welding op-
erations should be handled with care.
ELECTROMAGNETIC COMPATIBILITY.
This machine is manufactured in compliance with the in-
structions contained in the standard IEC 60974-10 (CL.
A), and must be used solely for professional purposes
in an industrial environment. There may be potential
difficulties in ensuring electromagnetic compatibility in
non-industrial environments.
HIGH FREQUENCY
• High frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
• Have only qualified persons familiar with
2
electronic equipment perform this installation.
• The user is responsible for having a qualified electrician
promptly correct any interference problem resulting from
the installation.
• If notified by the FCC about interference, stop using the
equipment at once.
• Have the installation regularly checked and maintained.
• Keep high-frequency source doors and panels tight-
ly shut, keep spark gaps at correct setting, and use
grounding and shielding to minimize the possibility of in-
terference.
DISPOSAL OF ELECTRICAL AND ELECTRONIC
EQUIPMENT.
Do not dispose of electrical equipment together
with normal waste!In observance of European Di-
rective 2002/96/EC on Waste Electrical and Electronic
Equipment and its implementation in accordance with
national law, electrical equipment that has reached the
end of its life must be collected separately and returned
to an environmentally compatible recycling facility. As the
owner of the equipment, you should get information on
approved collection systems from our local representa-
tive. By applying this European Directive you will improve
the environment and human health!
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
