The Excalibur 1/8 in. x 14 in. 7018-A1 MR Electrode comes in an easy-open 50 lb. can. 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. The electrode is ideal for use in most positions with the exception of a vertical downward position.
