E7018 AC mild steel "Low Hydrogen" welding rod easily produces quality results on smaller amperage AC/DC welders. It is suitable for all positions on hardenable steels where no pre-heat is used and on cold rolled steels normally exhibiting excessive porosity when welded with conventional rod. The low hydrogen content reduces cracking and peeling of the weld material. Features excellent restart capability. Designed for welding low, medium and high carbon steels as well as some higher strength low alloy steel.
