69500509 - Bonarc E71T-9 .035 Flux-Cored Wire 4.5kg Spool

High-Performance Structural Welding Wire

The Vanguard Bonarc E71T-9 .035" Flux-Cored Wire is a premium consumable designed for professional welders requiring superior mechanical properties and ease of use. Packaged in a convenient 4.5kg (approximately 10lb) spool, this wire is perfectly sized for portable wire feeders and smaller shop machines that utilize an 8-inch spool hub. Unlike self-shielded wires, this E71T-9 classification is a gas-shielded flux-cored wire (FCAW-G), engineered to run optimally with 100% CO2 shielding gas. This combination provides a deep penetrating arc and excellent fusion, making it a top choice for structural steel fabrication where weld integrity is paramount.

One of the standout features of the Bonarc E71T-9 is its operator appeal. It delivers a smooth, stable arc with significantly reduced spatter compared to conventional flux-cored options. The slag system is designed for easy removal, often peeling off in large sections to reveal a clean, high-quality bead profile. This reduces post-weld cleanup time and increases overall productivity in industrial environments. The wire is formulated for all-position welding, allowing operators to tackle complex joints in flat, horizontal, vertical-up, and overhead positions without sacrificing weld quality.

Industries relying on heavy equipment repair, shipbuilding, and general construction will appreciate the enhanced impact toughness provided by the T-9 classification. It meets rigorous standards for Charpy V-Notch impact properties, ensuring that welds remain durable even under stress or lower temperatures. Whether you are welding mild steel plate, structural beams, or machinery parts, the Vanguard Bonarc E71T-9 provides the consistency and performance professional fabricators demand.
