1. Use dry electrodes only.
2. If coating flux absorbs excessive moisture, arc and slag fluidity become unstable, spatters increase , undercuts and blowholes are apt to occur. Damp electrodes should be re-dried at 70～120℃ for 60 minutes.
3. For inclined and vertical downward positions , touch electrode tip lightly to the base metal and deposit a stringer bead with electrode slope 40～80°.
