This LA 7018 mild-steel electrode is a basic low hydrogen, all-position electrode (E7018-1) used on either DC or AC current. It can obtain code quality welds on higher strength steels with weld-metal toughness properties (charpy impacts) down to -46 Degrees C (-50 Degrees F), when coupled with a low hydrogen weld deposit. It is 18 inches in length with a 1/4-inch diameter, and meets CSA, Class E4918-1-H4 standards. Available in a five-kilogram package.
