\u25b6\ufe0e Characteristics<\/strong>:<\/h5>\n

LSF-56 is a neutral \ufb02ux. It is designed for multi-pass groove welds. With nice bead appearance, porosity resistance and good slag removability. High welding efficiency, good toughness can be obtained. It produces good impact property and minimum 500N\/mm\u00b2 tensile strength when used with LSW-EM12K.<\/p>\n

 <\/p>\n

\u25b6\ufe0e Notes on Usage<\/strong>:<\/h5>\n

1. Dry the \ufb02ux at 350\u00b0C for 60 minutes before use.
\n2. When performing first pass welding, it is recommend to use lower current to prevent cracking.<\/p>\n
