Characteristics:
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
Applications:
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
Notes on Usage:
- Use 100% CO2 shielding gas.
- Use DC(+) polarity.
- 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.
