APPLIANCES FOR RESISTANCE WELDING FOR INDUSTRIAL AND
PROFESSIONAL USE
Note:Inthefollowingtexttheterm“spotwelder”willbeused.
1.GENERALSAFETYRULESFORRESISTANCEWELDING
The operator should be properly trained to use the spot welder safely and
shouldbeinformedoftherisksconnectedwithresistanceweldingprocedures,
ofrelatedprotectionmeasuresandofemergencyprocedures.
(Onlyforpneumaticcylinder-operatedversions)Thespotwelderisprovided
withamainswitchwithemergencyfunctions,ttedwithapadlockforlockingit
inthe“O”(open)position.
The padlock key should be handed over only and exclusively to an expert
operator or to an operator who has been trained for the tasks assigned to
him and has beenwarnedof the possible hazardsarisingfrom this welding
procedureandfromneglectfuluseofthespotwelder.
Whentheoperatorisabsenttheswitchshouldbesettothe“O”position,the
padlockshouldbeclosedandthekeyremoved.
- Electrical installation should be carried out following accident-prevention
legislationandstandards.
- Thespotweldershouldbeconnectedonlyandexclusivelytoapowersupply
withtheneutralconductorconnectedtoearth.
- Make sure the power supply outlet is correctly connected to the earth
protection.
- Do not use cables with worn or damaged insulation or with loosened
connections.
- Usethespotwelderinanambientairtemperaturerangingfrom5°Cto40°C,
withrelativehumidityequalto50%uptoatemperatureof40°C,and90%for
temperaturesupto20°C.
- Donotusethespotwelderindamporwetenvironmentsorintherain.
- The connection of the welding cables and any routine maintenance
operationsonthearmsand/orelectrodesmustbecarriedoutwiththespot
welder switched off and disconnectedfromtheelectric and pneumatic (if
present)powersupplynetworks.Pneumaticcylinder-operatedspotwelders
shouldbelockedwiththemainswitchinthe“O”positionandthepadlock
closed.
Thesameprocedureshouldbe followedwhenmakingconnectionstothe
watersupplyortoaclosedcircuitcoolingunit(water-cooledspotwelders)
andwheneverrepairsaremade(extraordinarymaintenance).
- Whenusingspotweldersoperatedwithpneumaticcylinder,themainswitch
mustbelockedat“O”usingthesuppliedlock.
The
sameproceduremustberespectedwhenconnectingtothehydraulic
network or a closed circuit cooling unit (water cooled spot welders) and
wheneverrepairs(extraordinarymaintenance)arecarriedout.
- It is forbidden to use the equipment in environments comprising areas
classedasbeingatriskofexplosionbecauseofthepresenceofgas,dustor
mist.
- Do not weld on containers, receptacles or piping that contain or have
containedammableliquidorgasproducts.
- Donotoperateonmaterialscleanedwithcholorinatedsolventsornearsuch
substances.
- Donotweldonpressurisedcontainers.
- Removeallammablesubstancesfromtheworkarea(e.g.wood,paper,rags
etc.).
- Allownewly-weldedpiecestocool!Donotleavethepiecenearammable
substances.
- Make sure there is sufcient ventilation or provide means for removing
welding fumes near the electrodes; a systematic approach is necessary
to evaluate limits of exposure to the welding fumes depending on their
compositionandconcentrationandonthelengthofexposure.
- Alwaysprotecttheeyeswithsuitableeyeprotectors.
- Wearprotectiveglovesandclothingsuitableforresistanceweldingwork.
- Noiselevels:Ifthepersonaldailyexposurelevel(LEPd)isfoundtobegreater
than 85db(A) due to particularly intensive welding operations, wearing
personalprotectiondevicesiscompulsory.
- Theowingofspotweldingcurrentsgenerateselectromagneticelds(EMF)
aroundthespot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spotweldingmachinesareinoperation.
This spot welder 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spotweldingcables(ifpresent)asclosetogetheraspossible.
- Keepheadandtrunkasfarawayaspossiblefromthespotweldingcircuit.
- Neverwindspotweldingcablesaroundthebody.
- Avoidspotweldingwiththebodywithinthespotweldingcircuit.Keepboth
cablesonthesamesideofthebody.
- Connectthespotweldingcurrentreturncabletothepiecebeingspotwelded,
ascloseaspossibletotheweldingjoint.
- Donotspotweldwhilecloseto,sittingonorleaningagainstthespotwelder
(keepatleast50cmawayfromit).
- Do not leave objects in ferromagnetic material in proximity of the spot
weldingcircuit.
- Minimumdistance:
- d=3cm,f=50cm(Fig.E);
- d=3cm,f=50cm(Fig.F);
- d=30cm(Fig.G);
- d=20cm(Fig.H)Studder.
- ClassAequipment:
This spot welder 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.
INTENDED USE
Thesystemwasdesignedto be usedonlyandexclusivelyinbody shops to
repairvehicles:itmustbeusedforspotweldingoneormoresteelplateswith
alowcarboncontent,havingashapeandsizethatvaryaccordingtothework
tobecarriedout.
RESIDUAL RISKS
Theoperatingfunctionsofthespotweldingmachine donotforeseea push-
buttontostarttheweldingoperation,butsimplythecontactofthegunelectrode
withthemachinedpiececonnectedtotheearth:thereistheriskofstartingthe
weldingprocessbyinadvertentlyplacingthegunelectrodeontheearthorparts
connectedtothesame!
Whentheworkhasbeencompleted,placethegunonaninsulatingsurfaceand
switchoffthemachine!
- RISK OF BURNS
Somepartsofthespotwelder(electrodesarmsandnearbyareas)mayreach
temperaturesofover65°C:suitableprotectiveclothingmustbeworn.
Allownewly-weldedpiecestocoolbeforetouchingthem.
- RISK OF TIPPING AND FALLING
- Placethespotwelderonalevelhorizontalsurfacethatisabletosupport
itsweight;connethespotweldertothesupportsurface(whenrequired
in the “INSTALLATION” section of this manual). Otherwise with inclined
orunevenoorsormoveablesupportingsurfacesthereisthedangerof
tipping.
- Neverliftthespotwelderunlessexplicitlyrequiredbythe“INSTALLATION”
