Vanguard Bonarc E71T-9: Precision and Toughness

Upgrade your welding results with the Vanguard Bonarc E71T-9 .035" Flux-Cored Wire, available in a 4.5kg spool. This wire represents a significant step up in quality for fabricators working with carbon steel. Classified as E71T-9, this gas-shielded flux-cored wire is specifically formulated to provide excellent mechanical properties, particularly impact toughness, which is essential for welds subjected to dynamic loads or harsh environmental conditions. It is designed to be used with 100% CO2 shielding gas, which ensures deep penetration and reliable side-wall fusion.

The .035" (0.9mm) diameter is highly versatile, suitable for welding thin-to-medium gauge materials as well as multi-pass welds on thicker sections. The wire feeds smoothly through standard MIG guns, minimizing liner wear and feeding issues often associated with lower-quality cored wires. Welders will notice the exceptional puddle control this wire offers, particularly in out-of-position welding. The fast-freezing slag supports the weld pool in vertical and overhead positions, allowing for flat, consistent beads with minimal effort. Furthermore, the slag is easily detachable, leaving a bright, professional-looking finish that requires minimal grinding.

This 4.5kg spool is an ideal size for mobile welding rigs and workshops where swapping between different wire types is common. It offers enough material for substantial projects without the bulk of industrial drums. Whether you are fabricating structural frames, repairing agricultural equipment, or performing general maintenance, the Bonarc E71T-9 delivers the reliability and performance necessary to get the job done right the first time.

Performance Characteristics

• Gas Shielded Reliability: Uses CO2 to protect the weld pool, resulting in fewer porosity defects.
• All-Position Capable: Excellent performance in vertical-up and overhead welding.
• High Deposition Rate: Deposits weld metal faster than solid wires or stick electrodes, increasing efficiency.
