81933B - Hobart Megafil 819R 1/16-inch Seamless Flux-Cored Wire 35lb

Superior Performance with Hobart Megafil 819R

For welders who demand consistency and ease of use on high-strength steel projects, the Hobart Megafil 819R 1/16" wire delivers a top-tier experience. This isn't your average flux-cored wire; it utilizes seamless technology that makes it run as smoothly as a solid wire but with the fast deposition rates and all-position capabilities of a flux-core. If you are welding on heavy equipment, structural steel, or piping that requires 80,000 psi tensile strength, this wire provides the confidence you need to pass X-ray and ultrasound testing every time.

One of the biggest frustrations with traditional flux-cored wires is moisture pickup, which leads to worm-tracking and porosity. The Megafil 819R solves this with its hermetically sealed, copper-coated design. You can leave the spool on the feeder without worrying about it absorbing humidity overnight. When you pull the trigger, you get a smooth, stable arc with very low spatter, meaning less post-weld cleanup and grinding. The slag system is designed to be fast-freezing, allowing you to weld out-of-position—including vertical up—without the puddle sagging or dripping, giving you excellent bead control.

The 1/16-inch diameter allows for high deposition rates, helping you fill large joints faster and improve overall productivity. The copper coating also helps the wire slide easily through liners and guns, reducing bird-nesting and feeding issues that cause downtime. Whether you are working in a shop or on a site requiring high-impact toughness at low temperatures, the Megafil 819R is a reliable partner. It runs best on mixed gas (Argon/CO2), giving you a clean, professional-looking bead profile with deep penetration and solid fusion.
