HOBART® Fabshield® 21B Self Shielded Flux Core Carbon Steel Tubular Welding Wire with 0.045" Dia comes with 33 lb spool is used for nearly any general-purpose welding application and in any position. It works well on coated steels. It is ideal for single or multiple pass applications without the need of shielding gas. Wire finds applications in general fabrication, galvanized steels and repair welds. It features fast freezing, basic/fluoride type and flux-cored wire slag system. Wire features better operator appeal while offering enhanced productivity. It is versatile being ideal for various applications. It is great for welding outdoors and helps to pressure weld integrity while minimizing re-work. It features splendid bead appearance and better slag removal. It can be cleaned up easily and quickly. It is also applicable in non-alloyed and fine grain steels, pre-fab construction, rail car repairs, short assembly welds and light structural, machine parts and tanks. It has less tendency to burn through and is great for butt, fillet and lap joints on steel thicknesses from 16 gauge - 3/8". Without shielding gas required, it is a better choice for welding in hard-to-reach areas, where the provision of gas cylinders is not practical.
