S241012-032 - Hobart Fabco 101 .045" Gas-Shielded Flux-Cored Wire (10lb Spool)

Premium Performance for High-Strength Steels

Welders tackling projects involving T-1 (A514) or other high-strength low-alloy steels need a wire that matches the base metal's performance without compromising on weldability. The Hobart Fabco 101 .045" flux-cored wire is the answer. This gas-shielded wire is built to deliver 100 ksi tensile strength welds with the smooth runability Hobart is known for. Packaged in a 10 lb spool, it is perfect for use with portable wire feeders in the field or for shop projects where a full 33 lb spool isn't necessary. It allows you to produce code-quality welds with confidence, knowing the filler metal is designed to handle high stress and low temperatures.

Crack Resistance and Toughness

Cracking is a major concern when welding quenched and tempered steels, but Fabco 101 is engineered to mitigate this risk. It offers excellent crack resistance and low hydrogen levels, which are crucial for maintaining the integrity of the heat-affected zone in sensitive materials. The wire provides outstanding impact values at temperatures as low as -40°F, making it suitable for equipment that operates in freezing climates, such as mining machinery, offshore structures, and heavy earthmoving equipment. With Fabco 101, you get a deposit that is both strong and ductile.

Operator Appeal and Usability

What sets the Fabco 101 apart for the welder is its ease of use. The arc is soft yet penetrating, and the puddle is easy to manipulate in vertical and overhead positions thanks to the fast-freezing slag. Unlike some high-strength wires that can be difficult to run, Fabco 101 behaves much like a standard E71T-1 wire, allowing for high deposition rates and travel speeds. The slag coverage is complete but removes easily, often curling up on its own as the weld cools. This means less time chipping and grinding, and more time burning wire.

Versatile Applications

This wire is a go-to solution for a wide range of heavy-duty applications. From repairing boom arms on cranes to fabricating structural components for bridges and power plants, Fabco 101 delivers the mechanical properties required by engineers and the playability desired by welders. It is designed for use with 75% Argon / 25% CO2, a common gas mix in most shops, simplifying inventory and setup. Upgrade your welding capability for high-strength steels with the proven performance of Hobart Fabco 101.
