1. Drying Requirement: Electrodes must be baked at 250℃ for 1 hour before use and used immediately after baking.
2. Recommended Preheating Temperature: 200℃, with post-weld tempering at 760～790℃.
3. When using AC welding, spatter is higher, the coating is prone to reddening, and penetration is shallower; therefore, DC reverse polarity welding is recommended.
4. Use low current and short arc welding as much as possible during welding, with minimal oscillation amplitude.
