S224525-082 - Hobart Fabshield 4 5/64" Self-Shielded Flux-Cored Wire (20lb Spool)

The Heavy-Hitter for Outdoor Welding

When you need to lay down a lot of metal fast, and you don't want to worry about the wind blowing your shielding gas away, Hobart Fabshield 4 is the wire you reach for. This 5/64-inch self-shielded flux-cored wire is a legend in the field for a reason: it eats up heavy plate steel. Whether you are repairing an excavator bucket, welding structural beams on a high-rise, or fabricating in a drafty shop, Fabshield 4 delivers the performance you need without the hassle of dragging gas bottles around.

This wire is designed to run on DCEN (straight polarity), which gives it a distinct feel and deep penetration. It is known for its ability to burn through light rust and mill scale, saving you prep time on dirty steel. The bead profile is typically flat to slightly convex, and the slag system is designed for easy removal—often curling up on its own as it cools, so you spend less time chipping and more time welding. Because it is an E70T-4 class wire, it is strictly for flat and horizontal positions. Gravity is your friend here; the fluid puddle allows you to achieve very high travel speeds and deposition rates that solid wires just can't match in the field.

The 20lb spool size is a great balance between capacity and portability, fitting standard feeders while providing enough runtime for substantial jobs. The vacuum packaging ensures that when you crack the seal, the wire is as fresh as the day it was made, free from moisture that causes worm-tracking and porosity. If your job involves heavy steel and demanding schedules, Fabshield 4 is the workhorse that will get you across the finish line.

Why Welders Choose Fabshield 4:

• Speed: High deposition rates mean you finish long welds faster.
• Forgiving: Handles rust and mill scale better than most wires.
• Convenient: No gas regulator, hose, or bottle needed.
• Clean: Slag releases easily, minimizing post-weld cleanup.
