When your job involves welding thick steel that needs to withstand freezing temperatures and heavy loads, Hobart FabCO 803 is the wire you want in your feeder. This .045-inch flux-cored wire is built for the tough stuff—specifically 2% nickel steels found in shipbuilding, offshore oil rigs, and heavy construction equipment. If you are welding out on a dock or in a fabrication shop building structural beams for cold climates, this wire gives you the confidence that your welds won't crack when the temperature drops.
Welders appreciate FabCO 803 for its "fast-freezing" slag. What does that mean for you? It means you can weld in any position—flat, horizontal, vertical-up, or overhead—and the puddle stays where you put it. You won't be fighting gravity as much as you would with a fluid slag system. It lays down a flat, smooth bead with minimal spatter, which cuts down on your post-weld grinding and cleanup time. The slag peels off easily, often curling up on its own, so you can move on to the next pass quickly.
Versatility is another big plus. Whether your shop runs on 100% CO2 or an Argon mix, this wire runs smoothly on both. It provides deep penetration to ensure solid root fusion, and it handles multiple pass welds without issue. The 33lb spool fits standard industrial wire feeders, giving you plenty of runtime before a changeover. For professional welders tackling critical code work or heavy fabrication, FabCO 803 offers the reliability and performance needed to get the job done right the first time.
