Notes on Usage
Characteristics on Usage
It provides good bead appearance, better slag removal and together high impact value of the weld
metal. It is relatively insenitive to rust and dirt on a base metal, and makes better resistance to
pockmarks and pits. High impact values in both multi-run and two-run technique.
As the consumption of flux is low, it is very economical.
① Dry the flux at 300~350℃ (572~662°F ) for 60 minutes before use.
② When the flux height is excessive, poor bead appearance may occur.
③ Use welding current and speed as low as possible at the first layer of groove to avoid cracking.
