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°.
