(1)First pass only. On later passes, adjust arc speed to obtain proper bead size.

(2)Total for all passes. 100% operating factor.

Note: E7028 can produce code quality welds. E7028 is recommended for making high speed low cost welds using High-Deposition electrode (high iron powder) techniques described on pages 11-15.
