SPEZIAL MMA Electrodes C-Mn and low-alloy steels SPEZIAL is a basic, double-coated multi-purpose MMA electrode. The composition of the double coating confers exceptionally good welding characteristics and a highly stable and directional arc. Very good gap bridging and ideally suited for root passes and positional welding. The glassy slag is easily removed from the finely-rippled weld seams, the excellent welding characteristics and ISO-V toughness to -30°C. Structural steelwork, production and assembly jobs in industry and for pipeline construction for decades. Very good gap bridging and ideally suited for root passes. Material to be welded S(P)235; S(P)355; GP 240; GP 280; L 245; L260. ISO-V toughness at -30°C. Deposit free from porosity and good of X-ray quality. Optimum AC weldability requires an OCV > 65V. Very good gap bridging and ideally suited for root passes and positional welding.The glassy slag is easily removed from the finely-rippled. Classification EN ISO
