説明
特徴
LFC-309L is designed for 100% CO₂ gas and all-position welding. It performs with smooth arc transfer, low spatter level, fast freezing slag and good hot crack resistance
アプリケーション
It is suitable for welding dissimilar alloys in wrought or cast forms, or used in dissimilar welding such as low alloy steel, heat resistance steel and clad steel
使用上の注意
- Use 100% CO₂ シールドガス。
- DC(+)極性を使用する。
- Keep dry while in storage and delivery.
- Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
