Characteristics | LC-300NS is an extra low hydrogen type electrode for all-position welding of aluminumkilled steel used at low temperature and provides good usability. Weld metal is 0.5%Ni-Ti-B type, and has better notch toughness at -60℃ and CTOD properties at temperature down to -30℃. |
Notes on usage | (1) Dry the electrodes at 350~400℃ for about one hour before use. (2) Keep the arc short as possible. (3) Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values of weld metal. |
