  • Excellent Deoxidation: High levels of silicon (Si) and manganese (Mn) improve puddle fluidity and allow welding over surfaces with light rust or oil contamination.

  • Stable Arc & Smooth Bead: Produces a smooth, stable arc with minimal spatter, resulting in clean, aesthetically pleasing weld beads.

  • High Tensile Strength: Delivers a minimum tensile strength of 70,000 psi, providing strong and durable welds for structural applications.

  • Low Spatter and Easy Slag Removal: Clean finish with less post-weld cleanup effort.

  • Copper-Coated Surface: Enhances feedability and resists oxidation for extended shelf life.
