Deskripsi
Karakteristik:
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
Aplikasi:
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
Catatan tentang Penggunaan:
- Use 100% CO₂ gas pelindung.
- Gunakan polaritas DC (+).
- Jaga agar tetap kering saat dalam penyimpanan dan pengiriman.
- Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
