NOTES

1: PLS clear oil, rust, water and other impurities on the butt welding                    pieces before Welding.

2: The electrodes must be baked under 300~350°C for an hour before               welding and used as soon as baking is completed.

3: When welding, short arc must be used and stringer bead is suitable.

Product features

1:Stable arc  ; 2:Fewer spatters  ;3:Easy to restrike  ; 4:Less smog

5:Good off slag, high deposition efficiency
