Description
Characteristics:
LFC-347L is designed for 100% CO₂ gas and all-position welding. It performs with excellent slag removal, almost spatter-free. It provides good corrosion resistance in service temperature up to 760°C
Applications:
It is suitable for welding stabilized stainless steels such as types 347 and 321, nonstabilized austenitic stainless steel such as types 301, 302, 304 and CF-8.
Notes on Usage:
1. Use 100% CO₂ shielding gas.
2. Use DC(+) polarity.
3. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
4. To get enough penetration in the down hand welding position recommend maintaining a higher welding speed.
