POZOR: Dioda sveti samo pri preobremenitvi
Varilnik je opremljen s temperaturno zaščito, ki samodejno prekine napajanje varilnika. Takoj, ko notranja
temperatura ponovno pade pod vrednost, primerno za pravilno obratovanje, se varilnik samodejno zažene.
Varnostni napotki za rokovanje
Glejte tudi poglavje »Sekundarna nevarnost in varnostni ukrepi« in iz tega izhajajoče
varnostne ukrepe.
Benutzen Sie das Gerät erst nachdem Sie die Bedienungsanleitung aufmerksam gelesen haben.
Beachten Sie alle in der Anleitung aufgeführten Sicherheitshinweise.
Verhalten Sie sich verantwortungsvoll gegenüber anderen Personen.
Navodilo korak po koraku
Varjeno področje ne sme biti onesnaženo z rjo ali lakom. Elektrode se izberejo glede na vrsto materiala.
Priporočamo, da elektrodo najprej preizkusite na odpadnem materialu. Elektrode namestite v razdaljo ca. 2
cm nad izhodiščno točko. Uporabljajte le varilsko maso, varilske rokavice in primerno zaščitno obleko.
Dotaknite se obdelovanca, pri čemer na rahlo vlecite elektrodo.
Napačno
(predolgi lok)
Pravilno
(ca. 1 do 1,5 kratni premer elektrode)
Natančna dolžina obloka je odločilnega pomena, saj se z njo spreminja intenzivnost toka in napetosti.
Napačna intenzivnost toka negativno vpliva tako na zvar kot tudi na sam upor. Kot med elektrodo in
obdelovancem mora znašati 80 do 70 stopinj a v smeri pomika. Prevelik kot povzroči uhajanje žlindre pod
obrobni material. Če je kot premajhen, oblok niha in brizga. V obeh primerih je zvar porozen in oslabljen.
Napačno Napačno
Pravilno
Žlindra se sme odstraniti šele potem, ko se zvar ohladi. Z varjenjem prekinjenega zvara se lahko nadaljuje
šele po odstranitvi žlindre.
Napačno
Pravilno
Varilec mora poskušati zadržati konstantno dolžino obloka. Ker se elektroda obrablja, jo običajno mora
postopoma približevati obdelovancu. Na koncu zvara se priporoča odmik elektrode v smeri proti zvaru, da
se prepreči nastanek poroznega kraterja.
