INSTRUCTION MANUAL
WARNING:
BEFORE USING THE WELDING MACHINE READ THE
INSTRUCTION MANUAL CAREFULLY.
ARC WELDING MACHINES FOR COATED ELECTRODES (MMA)
FOR INDUSTRIAL AND PROFESSIONAL USE.
Note: In the following text the term “welding machine” will be used.
1.GENERALSAFETYCONSIDERATIONSFORARCWELDING
The operator should be properly trained to use the welding
machine safely and should be informed about the risks related
to arc welding procedures, the associated protection measures
and emergency procedures.
(Please refer to the applicable standard ”EN 60974-9: Arc
weldingequipment.Part9:InstallationandUse).
- Avoid direct contact with the welding circuit: the no-load
voltagesuppliedby thewelding machinecanbe dangerous
under certain circumstances.
- When the welding cables are being connected or checks
and repairs are carried out the welding machine should be
switched off and disconnected from the power supply outlet.
- Switch off the welding machine and disconnect it from the
power supply outlet before replacing consumable torch parts.
- Make the electrical connections and installation according to
the safety rules and legislation in force.
- The welding machine should be connected only and
exclusivelytoapowersourcewiththeneutralleadconnected
to earth.
- Make sure that the power supply plug is correctly connected
to the earth protection outlet.
- Do not use the welding machine in damp or wet places and do
not weld in the rain.
- Do not use cables with worn insulation or loose connections.
- Do not weld on containers or piping that contains or has
containedammableliquidorgaseousproducts.
- Donotoperateonmaterialscleanedwithchlorinatedsolvents
or near such substances.
- Do not weld on containers under pressure.
- Removeallammablematerials(e.g.wood,paper,ragsetc.)
from the working area.
- Provide adequate ventilation or facilities for the removal of
welding fumes near the arc; a systematic approach is needed
inevaluatingtheexposurelimitsfortheweldingfumes,which
will depend on their composition, concentration and the
length of exposure itself.
- Use adequate electrical insulation with regard to the electrode,
the work piece and any (accessible) earthed metal parts in the
vicinity.
This is normally achieved by wearing gloves, shoes, head
coverings and clothing designed for this purpose and by
using insulating platforms or mats.
- Alwaysprotectyoureyeswiththerelativelters,whichmust
comply with UNI EN 169 or UNI EN 379, mounted on masks or
use helmets that comply with UNI EN 175.
Use the relative re-resistant clothing (compliant with UNI
EN11611)andweldinggloves(compliantwithUNIEN12477)
without exposing the skin to the ultraviolet and infrared
rays produced by the arc; the protection must extend to
other people who are near the arc by way of screens or non-
reectivesheets.
- Noise: If the daily personal noiseexposure (LEPd) is equal
toor higherthan 85dB(A) becauseofparticularly intensive
weldingoperations,suitablepersonalprotectivemeansmust
be used (Tab. 1).
- The ow of the welding current generates electromagnetic
elds(EMF)aroundtheweldingcircuit.
Electromagnetic elds can interfere with certain medical
equipment (e.g. Pace-makers, respiratory equipment, metallic
prostheses etc.).
Adequate protective measures must be adopted for persons
with these types of medical apparatus. For example, they must
be forbidden access to the area in which welding machines are
in operation.
The operator must adopt the following procedures in order to
reduceexposuretoelectromagneticelds:
- Fasten the two welding cables as close together as possible.
- Keep head and trunk as far away as possible from the welding
circuit.
- Neverwindweldingcablesaroundthebody.
- Avoidweldingwiththebodywithintheweldingcircuit.Keep
both cables on the same side of the body.
- Connect the welding current return cable to the piece being
welded, as close as possible to the welding joint.
- Do not weld while close to, sitting on or leaning against the
welding machine (keep at least 50 cm away from it).
- Donotleaveobjectsinferromagneticmaterialinproximityof
the welding circuit.
- Minimum distance d= 20 cm (Fig. G).
- ClassBequipment:
This welding machine conforms to technical product standards
foruseinanindustrialenvironment,indomesticdwellingsand
inpremisesdirectly connectedto alow-voltagepower supply
system feeding buildings for domestic use.
EXTRA PRECAUTIONS
- WELDINGOPERATIONS:
- Inenvironmentswithincreasedriskofelectricshock;
- Inconnedspaces;
- Inthepresenceofammableorexplosivematerials;
MUSTBEevaluatedinadvancebyan“Expertsupervisor”
and must always be carried out in the presence of other
peopletrainedtointerveneinemergencies.
All protective technical measures MUST be taken as
provided in 7.10;A.8;A.10 of the applicable standard EN
60974-9: Arc welding equipment. Part 9: Installation and
Use”.
- WeldingMUSTNOTbeallowediftheweldingmachineorwire
feeder is supported by the operator (e.g. using belts).
- The operator MUST NOT BE ALLOWED to weld in raised
positions unless safety platforms are used.
- VOLTAGEBETWEENELECTRODEHOLDERSORTORCHES:
working with more than one welding machine on a single piece
or on pieces that are connected electrically may generate a
dangerous accumulation of no-load voltage between two
differentelectrodeholdersortorches,thevalueofwhichmay
reach double the allowed limit.
An expert coordinator must be designated to measuring
the apparatus to determine if any risks subsist and suitable
protection measures can be adopted, as foreseen by section
7.9 of the applicable standard ”EN 60974-9: Arc welding
equipment.Part9:InstallationandUse”.
RESIDUAL RISKS
- OVERTURNING:positiontheweldingmachineonahorizontal
surface that is able to support the weight: otherwise (e.g.
inclinedorunevenoorsetc.)thereisdangerofoverturning.
- IMPROPERUSE:itishazardoustousetheweldingmachine
for any work other than that for which it was designed (e.g.
de-icing mains water pipes).
