Hobart Fabco 110: High-Strength Flux-Cored Wire for Critical Applications

The Hobart Fabco 110 is a premium gas-shielded flux-cored wire designed specifically for welding high-strength low-alloy (HSLA) and quenched and tempered (Q&T) steels. With a diameter of 0.045 inches and packaged in a 33-pound spool, this wire is engineered to meet the rigorous demands of heavy industrial fabrication where structural integrity is paramount. It carries the AWS classification E110T1-K3C and E111T1-K3M, indicating its capability to produce welds with a minimum tensile strength of 110,000 psi.

Technical Performance and Metallurgy

Fabco 110 utilizes a nickel-molybdenum-manganese alloy system to achieve its high mechanical properties. This formulation ensures that the weld metal matches the strength and toughness requirements of steels such as ASTM A514, HY-80, and T-1. A key technical advantage of this wire is its low diffusible hydrogen content (typically below 5.0 ml/100g), which is critical for preventing hydrogen-induced cracking (cold cracking) in these sensitive high-strength materials. The wire is designed for use with a shielding gas mixture of 75% Argon and 25% CO2, which helps stabilize the arc and refine the droplet transfer.

Operational Characteristics

Welders utilizing the Fabco 110 will appreciate its excellent operator appeal. The wire features a fast-freezing slag system, making it highly suitable for all-position welding, including vertical-up and overhead applications. The arc is smooth and stable, producing a flat bead profile with minimal spatter, which reduces post-weld cleanup time. The slag is easily removable, often peeling away to reveal a clean weld face. This wire is an essential consumable for shops fabricating heavy equipment, cranes, and offshore structures where standard mild steel wires are insufficient.

Storage and Handling

To maintain the low-hydrogen properties of the Fabco 110, proper storage is essential. The 33lb spool is packaged to protect against moisture absorption. It is recommended to store the wire in a dry, controlled environment and to return spools to their original packaging or a rod oven if left exposed for extended periods in high-humidity conditions.
