Hobart Fabco 115 1/16-inch Flux-Cored Wire 60lb Coil

Heavy-Duty Welding with Fabco 115

When you are welding on cranes, earthmovers, or heavy mining chassis, you aren't just laying beads—you are ensuring the structural integrity of massive machines that carry tons of weight. For these high-stakes jobs, standard mild steel wire won't cut it. You need the Hobart Fabco 115. This 1/16-inch flux-cored wire is built for the big leagues, delivering over 110,000 psi of tensile strength to match those high-yield T-1 and HY-80 steels you are working with. It is the wire you grab when the print calls for E110T5-K3 and the inspector is watching like a hawk.

The Fabco 115 uses a basic slag system. If you're used to running all-position rutile wires, you'll notice this runs a bit differently. It is designed for the Flat and Horizontal positions, where it lays down a smooth, flat bead with deep penetration. The slag is a bit heavier, but that's what scrubs the weld pool clean and keeps your hydrogen levels low—critical for preventing cracks in thick, restrained joints. Once you get the settings dialed in, the arc is stable, and the slag often curls up and peels off by itself, leaving a clean weld face that requires minimal post-weld cleanup.

This 60lb coil format is perfect for shop environments where you are burning wire all day. Fewer changeovers mean more arc-on time. Whether you are repairing a boom arm or fabricating a new pressure vessel support, this wire gives you the confidence that your welds will hold up to extreme cold and heavy shock loads. It runs on standard DC+ polarity and works with either straight CO2 or a 75/25 Mix, giving you flexibility based on what gas you have plumbed in the shop.

Don't risk a callback or a failed X-ray on critical heavy equipment repairs. The Fabco 115 is formulated to resist cracking even when the steel is thick and the stress is high. It’s the professional choice for heavy industrial fabrication where strength and toughness are the top priorities.
