MANUALE ISTRUZIONE
Read this instruction manual carefully before using
the welding machine.
The MMA and TIG coated electrode arc welding systems
referred to herein as "welding machines" are for industrial
and professional use.
Make sure that the welding machine is installed and repaired
only by qualified persons or experts, in compliance with the
law and with the accident prevention regulations.
Make sure that the operator is trained in the use and risks
connected to the arc-welding processs and in the necessary
measures of protection and emergency procedures.
Detailed information can be found in the "Installation and use
of arc-welding equipment" brochure:": EN 60974-9.
AVVERTENZE DI SICUREZZA
Make sure that the power socket to which the welding
machine is connected is protected by suitable safety
devices (fuses or automatic switch) and that it is
grounded.
• Make sure that the plug and power cable are in good
condition.
• Before plugging into the power socket, make sure that the
welding machine is switched off.
• Switch the welding machine off and pull the plug out of the
power socket as soon as you have finished working.
• Switch the welding machine off and pull the plug out of
the power socket before connecting the welding cables,
replacing any parts in the torch or wire feeder, carrying
out maintenance operations, or moving it (use the carrying
handle on the welding machine).
• Do not touch any electrified parts with bare skin or wet
clothing. Insulate yourself from the electrode, the piece to
be welded and any grounded accessible metal parts. Use
gloves, footwear and clothing designed for this purpose and
dry, non-flammable insulating mats.
• Use the welding machine in a dry, ventilated space. Do not
expose the welding machine to rain or direct sunshine.
• Use the welding machine only if all panels and guards are
in place and mounted correctly.
• Do not use the welding machine if it has been dropped or
struck, as it may not be safe.
Have it checked by a qualified person or an expert.
• Eliminate any welding fumes through appropriate
natural ventilation or using a smoke exhauster. A
systematic approach must be used to assess the
limits of exposure to welding fumes, depending on
their composition, concentration and the length of
exposure.
• Do not weld materials that have been cleaned with chloride
solvents or that have been near such substances.
• Use a welding mask with adiactinic glass suited for welding.
Replace the mask if damaged; it may let in radiation.
• Wear fireproof gloves, footwear and clothing to protect the
skin from the radiation produced by the welding arc and from
sparks. Do not wear greasy garments as a spark could set
fire to them. Use protective screens to protect people nearby.
• Do not allow bare skin to come into contact with hot metal
parts, electrode holder grippers, electrode stubs, or freshly
welded pieces.
• Metal-working gives off sparks and splinters. Wear safety
goggles with protective side eye guards.
• Welding sparks can trigger fires.
• Do not weld or cut anywhere near inflammable materials,
gasses or vapours.
• Do not weld or cut containers, cylinders, tanks or piping
unless a qualified technician or expert has checked that it is
possible to do so, or has made the appropriate preparations.
• Remove the electrode from the electrode holder gripper
when you have completed the welding operations. Make
sure that no part of the electrode holder gripper electric circuit
touches the ground or earth circuits: accidental contact could
cause overheating or trigger a fire.
EMF Electromagnetic Fields.
Welding current creates electromagnetic fields (EMF) near
the welding circuits and the welder. Electromagnetic fields
may interfere with medical prostheses such as pacemakers.
Suitable and sufficient measures should be implemented
to protect those operators having such aids. For instance,
they should not be allowed to enter that area where welding
equipment is used. Any operator having such aids should
consult their doctor before coming close to an area where
welding equipment is used.
This device meets the specific requirements of the product
technical standard and is intended for professional use in an
industrial environment only. Compliance to expected limits
for human exposure to electromagnetic fields at home is not
ensured.
Follow these strategies
electromagnetic fields (EMF):
• Do not place your body between the welding cables. Both
welding cables should be on the same side of your body.
• Twist both welding cables together and secure them with
tape when possible.
• Do not wrap the welding cables around your body.
• Connect the earth cable to the workpiece as close as
possible to the area to be welded.
• Keep your head and trunk as far as possible from the
welding circuit. Do not work close to the welder, or seated
or leaning on it. Minimum distance: Fig. 5 Da = cm 50; Db
= cm.20
Class A equipment
This equipment has been designed to be used in professional
and industrial environments.
If this equipment is used in domestic environments and those
directly connected to a low voltage power supply network
which supplies buildings used for domestic purposes, it
may be difficult to ensure compliance to electromagnetic
compatibility as the result of conducted or radiated
disturbances.
Welding in conditions of risk
• If welding needs to be done in conditions of risk (electric
discharges, suffocation, the presence of inflammable or
explosive materials), make sure that an authorised expert
evaluates the conditions beforehand. Make sure that
trained people are present who can intervene in the event
of an emergency. Use the protective equipment described in
notmative of EN 60974-9.
• If you are required to work in a position raised above ground
level, always use a safety platform.
• If more than one welding machine has to be used on the
same piece, or in any case on pieces connected electrically,
the sum of the no-load voltages on the electrode holders or
on the torches may exceed the safety levels.
