K-T 7018 is a general-purpose, low moisture absorption, low hydrogen electrode. This electrode features easy start and restart performance, easy slag removal which lends itself for easy tacking before finish welding. Low spatter and flat beads, make good looking welds and less clean up. Very easy to control and a very stable arc. Superior weld appeal. Use for a variety of steels including low, medium and high- carbon steels, low alloy structures and high- carbon castings. Can be used in AC or DC+. 7018's typical applications include pressure vessels, cold-rolled steels and structural steels. 70000 psi tensile strength. Not recommended for low-voltage AC welders .
