1-5 EMF Information
Electriccurrentflowingthroughanyconductorcauseslocalized
electricandmagneticfields(EMF).Thecurrentfromarcwelding
(andalliedprocessesincludingspotwelding,gouging,plasmaarc
cutting,andinductionheatingoperations)createsanEMFfield
aroundtheweldingcircuit.EMFfieldsmayinterferewithsome
medicalimplants,e.g.Pacemakers.Protectivemeasuresfor
personswearingmedicalimplantshavetobetaken.Forexample,
restrictaccessforpassersbyorconductindividualriskassessment
forwelders.Allweldersshouldusethefollowingproceduresin
ordertominimizeexposuretoEMFfieldsfromtheweldingcircuit:
1. Keepcablesclosetogetherbytwistingortapingthem,or
usingacablecover.
2. Donotplaceyourbodybetweenweldingcables.Arrange
cablestoonesideandawayfromtheoperator.
3. Donotcoilordrapecablesaroundyourbody.
4. Keepheadandtrunkasfarawayfromtheequipmentinthe
weldingcircuitaspossible.
5. Connectworkclamptoworkpieceasclosetotheweldas
possible.
6. Donotworknextto,sitorleanontheweldingpowersource.
7. Donotweldwhilstcarryingtheweldingpowersourcewire
feeder.
