This 0.030 in. inner shield NR-211-MP wire 10 lb. spool has high operator appeal and good bead appearance. There's a long list of reasons why operators are so loyal to Excalibur 7018 MR. They tell us they love the clean puddle, the square coating burn off, the easy all-position handling and the excellent wash-in characteristics. It’s a terrific choice for jobs that involve steels with poor weld ability.
