OVERVIEW

Superior Weldability with Hobart Fabco 91K2-M

Elevate your welding projects with the Hobart Fabco 91K2-M, a .045-inch flux-cored wire designed for professional welders who demand both strength and ease of use. This wire is classified under AWS E91T1-K2M, indicating its suitability for welding steels with a tensile strength of 90,000 psi. It is specifically formulated to provide outstanding mechanical properties, making it a go-to filler metal for structural fabrication where standard mild steel wires may not suffice. The "M" in its classification denotes that it is optimized for use with mixed shielding gases, providing a smooth arc and deep penetration.

One of the standout features of the Fabco 91K2-M is its operator appeal. The wire feeds smoothly through standard MIG guns and establishes a crisp arc with low fume generation, creating a more comfortable working environment. The slag system is designed to detach easily, often curling up on its own as the weld cools, which reveals a clean, smooth bead profile underneath. This reduces the need for aggressive grinding or chipping, allowing welders to move on to the next pass or finish the job faster. Its ability to weld in all positions without sacrificing bead quality makes it incredibly versatile for on-site repairs and complex assemblies.

The 33lb spool size is standard for industrial wire feeders, and the vacuum-sealed packaging ensures that you get the best possible performance right out of the box. This wire is particularly effective for joining ASTM A514, A710, and similar high-strength steels often found in crane manufacturing, earthmoving equipment, and marine structures. With the Fabco 91K2-M, you get the perfect balance of high-performance metallurgy and practical weldability.

Performance Highlights

  • Enhanced Strength: Ideal for 90 ksi tensile strength steel applications.
  • Operator Friendly: Smooth arc, low spatter, and easy slag release.
  • Versatile Application: Excellent for shipbuilding, pipelines, and heavy machinery.

FAQ

This wire is designed for use with a mixed gas, typically 75% Argon and 25% CO2.

The AWS classification is E91T1-K2M-H4.

Yes, the Fabco 91K2-M has a fast-freezing slag that makes it suitable for all-position welding, including vertical-up and overhead.

The wire produces a weld deposit with a tensile strength in the range of 90,000 psi (90 ksi).

It comes in a Vacuum Packed Spool (VPSP) to protect against moisture. Once opened, it should be stored in a dry environment or a rod oven if necessary to maintain low hydrogen levels.

This wire operates on Direct Current Electrode Positive (DCEP), also known as DC+.

It is suitable for both single and multiple pass applications.

The wire contains approximately 1.5% Nickel to improve impact toughness at low temperatures.
