Abstract
A cored type arc-welding steel electrode for the welding of 14 gauge to 3/8 inch thick mild steel wherein the ingredients in the core provide a smooth spray arc that is easy to control along with excellent bead appearance, low spatter, and good slag removal. The core ingredients include: calcium oxide, as a necessary compound, in a prefused mix to lower its hygroscopicity; aluminum and magnesium in controlled amounts; and selected fluorides.
