Description: AFM ER70S-6 is intended for both single- and multi-pass welding. It is especially suited for sheet metal applications, where smooth weld beads are desired, and structural and plate steels that have moderate amounts of rust or mill scale. AFM ER70S-6 withstands high currents with CO©üshielding, even when welding rimmed steels. Typical base metal specifications are often the same as those for AFM ER70S-2.
