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.
- Keep the gas bottle (if used) away from heat sources, including direct
sunlight.
- Useelectricinsulationthatissuitableforthetorch,theworkpieceandany
metalpartsthatmaybeplacedonthegroundandnearby(accessible).
Thiscannormallybedonebywearinggloves,footwear,headprotectionand
clothingthataresuitableforthepurposeandbyusinginsulatingboards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.
Thiswelding machineconforms totechnicalproductstandardsfor exclusive
useinanindustrialenvironmentforprofessionalpurposes.Itdoesnotassure
compliancewiththebasiclimitsrelativetohumanexposuretoelectromagnetic
eldsinthedomesticenvironment.
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.O).
-ClassAequipment:
Thiswelding machineconforms totechnicalproductstandardsfor exclusive
use in an industrial environment and for professional purposes. It does not
assure compliance with electromagnetic compatibility 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riskof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”.
-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).
- Donotusethehandletohangtheweldingmachine.
