MMA manual metal arc welding systems using coated
electrodes with limited service are referred to herein as
“welding machines”.
- 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 processes 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: IEC or
CLC/TS 62081.
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
Make sure that the plug and power cable are in good
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
Switch the welding machine off and pull the plug out
of the power socket before connecting the welding
cables, installing the continuous wire, 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
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
welding. Replace the mask if damaged; it may let in
Wear fireproof gloves, footwear and clothing to protect
the skin from the rays 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, such as the torch, 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.
The magnetic fields deriving from the welding current
may interfere with electrical and electronic equipment.
People fitted with vital electrical devices (pacemakers
etc.) should consult a doctor prior to coming into
contact with welding equipment.
This welding machine satisfies the requirements of
the technical product standard exclusively for
professional and industrial use. Compliance with
electromagnetic compatibility for domestic use is
not guaranteed.
The welding machine is installed and used under
your own responsibility. In the event of electromagnetic
disturbance, this should be reduced so that it does
not cause problems. Ask a competent expert for
technical assistance if required.
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 protective equipment described in the IEC or
CLC/TS 62081 technical specification.
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. Make sure that an authorised expert
evaluates the conditions beforehand to see if such
risk exists and adopt the protective measures described
in 5.9 of the IEX or CLC/TS 62081 technical
specification if required.
- Do not use the welding machine for purposes
other than those described. For example to thaw
frozen water pipes.
- Place the welding machine on a flat stable surface.
and make sure that it cannot move. It must be
positioned in such a way as to allow it to be controlled
during use but without the risk of being covered with
welding sparks.
- Do not work with the welding machine hung from the
body, using straps or any other device.
- Do not lift the welding machine. No lifting devices are
fitted on the machine.
- Do not use cables with damaged insulation or loose

UNPACKING: After removing the packing material, make sure the product is in perfect
condition and that there are no visible damaged parts. If in doubt, do not use the product
and contact the dealer from whom it was purchased.
The packaging materials (plastic bags, polystyrene, etc.), must be disposed of in an
appropriate refuse collection container. These materials must not be left within the reach of
children as they are potential sources of danger.

The warning light switched on means that the
thermal protection is running.
If the welding time “tw” indicated in the data plate
is exceeded, a thermal cutout stops operation
before the welder is damaged. Wait for operation
to be resumed and, if possible, wait a few minutes
If the thermal cutout continues to cut in, the
welding machine is being pushed beyond its
normal performance levels.
Only use an extension lead when absolutely
necessary and providing it has an equal or larger
section to the power cable and is fitted with a
grounding conductor.
Do not block the welder air intakes. Do not store
the welder in containers or on shelving that does
not guarantee suitable ventiliation.
Do not use the welder in any environment in the
presence of gas, vapours, conductive powders
(e.g. iron shavings), brackish air, caustic fumes or
other agents that could damage the metal parts
and electical insulation.
The electric parts of the welder have been
treated with protective resins. When used for the
first time, smoke may be noticed; this is caused
by the resin drying out completely. The smoke
should only last for a few minutes.
Regular inspection and cleaning reduces the necessity for maintenance operations and will keep
your tool in good working condition.
The motor must be correctly ventilated during tool operation. For this reason avoid blocking the
air inlets. After use disconnect the tool from the power supply and vacuum the ventilation slots.
If the replacement of the supply cord is necessary, this has to be done by the manufacturer or his
agent in order to avoid a safety hazard.
- At the end of the machines working life, or when it can no longer be repaired, ensure that it
is disposed of according to national regulations.
- Contact your local authority for details of collection schemes in your area.
