DESCRIPTION
A rutile-coated, iron powder electrode with 140 % deposition efficiency intended for horizontal and fillet welding of heavier section construction steel. Weldable in flat and horizontal positions only. Gives good finish welds and easy slag removal properties. The welding speed is relatively higher. Spatter loss is negligible. Deposition efficiency is approximately 140 %.
