Notes on usage:

1. Dry the flux at 300—350℃ for 1—2hr if there is any concern about moisture pick-up while opening the pack.

2. When performing first pass welding, it's recommended to use lower current to prevent
3. Adding proper quantity of new flux with the used one to maintain good quality of weld metal.
