Usage Guidelines:
- Electrode Drying: Before use, dry the electrodes at 350-400°C (662-752°F) for 1 hour to remove moisture.
- Preheating: Preheat workpieces to 150-300°C (302-572°F) to prevent thermal stress.
- Post-Weld Heat Treatment (PWHT): Heat the welded component to 690°C (1274°F) for 1 hour for optimal mechanical properties.
