INSTRUCTION MANUAL FOR ARC 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.
1 SAFETY PRECAUTIONS
WELDING AND ARC CUTTING CAN BE
HARMFUL TO YOURSELF AND OTHERS.
The user must therefore be educated
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 work-
piece.
· 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
filtered lenses, and protect your body with appro- priate 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
flammable materials in the area, and wear appro-
priate protective garments.
NOISE This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding pro-
cedure may produce noise levels beyond said
limit; users must therefore implement all precautions
required by law.
ELECTRIC AND MAGNETIC FIELDS - May be dangerous.
· Electric current following through any conduc-
tor 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) should consult their phy-
sician before 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 order to
minimize exposure to EMF fields from the welding/cutting cir-
cuit:
- 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 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 standard IEC 60974-10 (CL. A),
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.
DISPOSAL OF ELECTRICAL AND ELECTRONIC
EQUIPMENT
Do not dispose of electrical equipment together
with normal waste!In observance of European
Directive 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 represen-
tative. By applying this European Directive you will improve the environment and human health!
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
