Item Details

  • Hobart® 418 Hermetically Sealed Container Carbon Steel Electrode is an all position, low hydrogen electrode used to produce virtually spatter free, smooth, good stable arc with start and restart capability in addition by featuring good wetting action along with low moisture absorption rate. 1/4" Electrode is ideal for single as well as multiple pass, DCEP, AC and comes with slag design that makes removal easier features flat bead contour with a fine ripple appearance that eliminates the need of undercutting and cold lap. Electrode meets AWS E7018-1 requirements with the specifications tensile strength of 78500 psi and yield strength of about 65500 psi and has good weldability with no porosity used to weld with low, medium, high-carbon steels with low-alloy structural and can be used to weld even when welding surface is dirty or rusty. Electrode is employed in various applications like rail cars, steel structures/field erections, shipbuilding/barge offshore drilling rigs and power, petrochemical, boiler plants by minimizing the potential for hydrogen cracking that enhances productivity. Electrode is perfect for general fabrication/maintenance, heavy equipment fabrication as well as repair, non-alloyed and fine grain steels and is compatible with Fabshield® tubular wires. Electrode is sold as a 50 lb hermetically sealed container.
