(Flux Cored Stainless Wire)
▶︎ Characteristics:
LFC-309H is a special for 100% CO₂ or Ar+15-25%CO₂ gas and all-position welding. With excellent slag removal, good resistance to intergranular corrosion and good for welding dissimilar meals.
▶︎ Applications:
It is suitable for welding of dissimilar metals such as stainless steel and carbon steel or stainless steel andlow alloy
▶︎ Notes on Usage:
1. Use 100% CO₂ or Ar+15-25%CO₂ shielding gas.
2. Keep dry while in storage and delivery.
3. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
