1 Rev. 03 FLUX CORED ARC WELDING CONSUMABLE FOR WELDING OF 18% Cr-8% Ni STAINLESS STEEL HYUNDAI WELDING CO., LTD.

2 v Specification JIS Z3323 E308LT1-1/-4 TS308L-FB1 EN ISO A T19 9 L P M21/C1 2 v Applications is designed for welding of 18%Cr-8%Ni stainless steels. v Characteristics on Usage is suitable for all position welding makes easier re-arcing, beautiful bead appearance and better slag removability. This wire benefit from a fast freezing slag system which assist the operator when welding out of position and performs equally as well when welding in the flat and horizontal position. v Note on Usage Use 100% CO 2 gas or Ar+20~25% CO2 gas v Packing Diameter 0.9mm (0.035in) 1.2mm (0.045in) 1.4 (0.052in) 1.6 (1/16in) Spool *including ball pac 5kg (11lbs) 12.5kg (28lbs) 15kg (33lbs) 20kg (44lbs)
