Ferrocraft 21 is a rutile type, medium iron powder arc welding electrode designed for professional welders and fabricators. It is suitable for use with both AC and DC power sources, including low open circuit voltage (O.C.V.) welding machines.

This electrode delivers smooth and stable arc performance, producing excellent fillet weld shapes in all positions, including vertical down, vertical up, and overhead. It offers a higher electrode efficiency of 110%, enhancing productivity and reducing waste.

Key features include:

• Rutile type coating with medium iron powder for improved weld quality
• Excellent operator appeal due to easy striking and stable arc
• Versatile application across all welding positions
• Ideal for vertical down fillet welding
• Reliable impact toughness down to -20°C

Ferrocraft 21 electrodes are well-suited for structural steel fabrication and general maintenance welding where consistent weld quality and ease of use are essential.
