Developed specifically for military applications. Another Dual Shield II electrode with high strength and excellent impact properties. For all-position welding of 110,000 psi steels such as HY-100, T1 and others. For flat & horizontal welds on 100,000 psi tensile strength steels. A significant new electrode with high strength and excellent ductility. An all- position electrode for welding the T-1 and HY-80 steels. Excellent low temperature impacts. For flat & horizontal welds on 110,000 psi steels. For trade name steels such as SSS 100, N-A-XTRA 110, JALLOY S110, USS T1 Type A and others. For flat & horizontal welds. A basic slag electrode with excellent properties. Small diameters require Argon-CO₂ mixture for high current, high deposition welding. For welding T1, HY-80, HY-90, N-A-XTRA 90, 100 & 110 and the SSS 100 steels.
