obdelujemo, ta razdalja se ujema s premerom elektrode, ki jo uporabljamo;
zapomnite si, da mora biti elektroda pod kotom 20-30 stopinj v smeri obdelovanja.
- Na koncu varjenja zasukajte elektrodo rahlo nazaj glede na smer obdelave nad
kraterjem, da bi ga zapolnili, ter jo s hitrim gibom odmaknite iz varilnega kraterja,
tako da bo oblok ugasnil (Videz zvara - SLIKA M).
