Product Introduction
71T-1 Flux-Cored Welding Wire – All-Position, High-Efficiency CO2 Gas-Shielded
Designed for demanding structural welding, the 71T-1 combines a soft, stable arc with low spatter and easy slag removal. Its deposited metal undergoes micro-alloying for low-temperature toughness, making it a reliable choice for carbon steel and low-alloy steel fabrication where weld quality and efficiency are critical.
Key Features & Benefits:
Flux-Cored vs. Solid – Key Advantages
Compared with solid wire, the 71T-1 Series flux-cored wire offers a significantly higher deposition rate, allowing more weld metal to be deposited per unit of time for greater productivity.The flux core also improves current density, promoting faster wire melting and further boosting deposition efficiency.
Smooth Arc & Clean Welding
The rutile (titania) flux formulation delivers a soft and stable arc, minimal spatter, and easy slag detachability. Weld beads are smooth and well-formed, reducing post-weld cleaning time and improving overall productivity.

All-Position Capability with High Deposition Efficiency
Suitable for flat and horizontal welding, as well as all-position operation, the wire supports efficient, high-deposition welding across diverse joint configurations. This makes it adaptable to both shop fabrication and field work.
