Description
Characteristics:
LFC-318 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 stabilized stainless steel as CrNi(N) and CrNiMo(N)
Notes on Usage:
1. Use 100% CO₂ shielding gas.
2. Use DC(+) polarity.
3. Keep dry while in storage and delivery.
4. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
