S283312-K29 - Hobart TM-771 .045 Flux-Cored Wire 33lb Spool

Experience Smoother Welds with Hobart TM-771

If you are looking for a flux-cored wire that makes vertical and overhead welding feel almost as easy as flat welding, the Hobart TM-771 is the answer. This .045-inch wire comes in a 33lb spool and is designed to run exclusively on 100% CO2, keeping your gas costs down while delivering premium performance. What sets the TM-771 apart is its incredible "operator appeal"—welder-speak for a wire that just runs beautifully. You get a soft, buzzing arc that doesn't fight you, and the spatter is so minimal you might barely need your grinder when you're done.

Master Out-of-Position Welding

Struggling with sagging puddles on vertical-up joints? The TM-771 features a fast-freezing slag that acts like a shelf, holding your molten metal in place while you weave. This makes it exceptionally forgiving for all-position structural work. Once the weld cools, the slag often curls up and peels off by itself, or comes off with a light tap, revealing a professional-looking bead with deep penetration and solid fusion. It’s the kind of wire that makes a good welder look great and a great welder look flawless.

Built for the Tough Jobs

This isn't just a hobbyist wire; it's built for heavy-duty fabrication. From repairing heavy farm equipment and railcars to building structural steel frames and ship hulls, the TM-771 offers the strength and toughness you need. It is a low-hydrogen wire, meaning the welds are resistant to cracking even under high stress. Because it is designed for both single and multi-pass welds, you can lay down heavy fillets or fill deep grooves without worrying about inclusion or porosity issues, provided your settings are dialed in.

Ready to Run

The 33lb spool size is standard for industrial wire feeders, giving you plenty of arc time between changeovers. The vacuum packaging ensures the wire arrives fresh and free of moisture, ready to burn the moment you crack the seal. If your shop relies on CO2 shielding gas and needs a versatile, all-around workhorse for carbon steel, the Hobart TM-771 is a top-tier choice that balances cost, performance, and ease of use.
