Shield-Bright 309L X-tra

Shield-Bright 309L X-tra is a gas‑shielded stainless steel flux‑cored wire (FCAW/MCAW) designed for 22% Cr – 12% Ni stainless steel welding in flat and horizontal positions. It provides superior operability, easy slag release, and low spatter for clean welds.

Key Features

• Gas‑shielded flux‑cored wire for all‑position welding
• Fast‑freezing slag gives flat weld deposits
• Spray transfer mode with mixed or pure CO₂ shielding
• Low spatter and easy slag release for reduced post‑weld cleaning
• Available in 1.2 mm and 1.6 mm diameters
