描述
特性：
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.
應用：
It is suitable for welding of dissimilar metals such as stainless steel and carbon steel or stainless steel andlow alloy
使用注意事項：
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.
