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.
✔ Very stable arc and insensitive to the effects of arc blow.
✔ Sustained and high quality fusion with a very low welding current setting.
✔ Excellent operator appeal.
✔ Exceptional wetting even at low current.
✔ High flexibility for irregular gap.
✔ High Metallurgical deposit purity.
During manufacturing the two coatings are pressed simultaneously in a single extrusion operation. Both coatings from different chemical compositions but very complementary, will give a better technical result.
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;
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.
