S282419-002 - Hobart Fabco 101K3 1/16" Flux-Cored Welding Wire - 60lb Coil

Toughness and Control for High-Strength Steels

When your project involves high-yield steels like HY-80, A710, or A514, you need a consumable that matches the base material's toughness without fighting you on the arc. The Hobart Fabco 101K3 is built for exactly these challenges. This 1/16" flux-cored wire is a go-to solution for welders who need to lay down high-strength deposits that can withstand significant stress and impact, even at lower temperatures. It is designed to run smoothly on 100% CO2, giving you a deep-penetrating arc that cuts into the sidewalls for solid fusion, while keeping your gas costs manageable.

Welders will appreciate the "fast-freeze" slag characteristics of the Fabco 101K3. Unlike some high-strength wires that become fluid and difficult to control out of position, this wire supports the puddle effectively in vertical-up and overhead welds. The slag lifts easily, often peeling off in large sections, which reduces cleanup time and the risk of slag inclusions in multi-pass applications. This makes it a favorite for heavy equipment repair, crane fabrication, and ship hull work where weld integrity cannot be compromised.

Reliability is key in heavy fabrication, and the Fabco 101K3 delivers consistent mechanical properties that meet strict code requirements. The 60lb coil format ensures you have plenty of material on the feeder for long runs, reducing interruptions. With its ability to produce X-ray quality welds and its resistance to cracking, this wire gives professional welders the confidence that their work will hold up under the most demanding service conditions. If you are welding quenched and tempered steels and need a wire that balances high performance with welder appeal, the Fabco 101K3 is the tool for the job.
