Hobart MEGAFIL 713R .045 Seamless E71T-1 Flux Core Wire

Experience the Smoothness of Seamless Flux Core

Welders know that not all flux core wires are created equal. The Hobart MEGAFIL 713R .045 Seamless Flux Core Wire is built to make your job easier and your welds stronger. If you are tired of fighting with porosity caused by moisture pickup in your wire, the MEGAFIL 713R is the solution. Its seamless, copper-coated design means the flux is completely sealed inside a solid steel tube. It doesn't absorb humidity from the shop air, so you get a fresh, low-hydrogen weld every time you strike an arc, without needing to bake the wire or store it in a hot box.

In the booth or on the site, this wire runs with a buttery smooth arc that rutile wires are famous for. It produces very low spatter, which means less time spent grinding and cleaning up after the weld. The slag is fast-freezing but easy to remove, often peeling off by itself. This characteristic makes it exceptional for out-of-position work; vertical-up welds lay in flat and consistent without the sagging common in slower-freezing wires. It gives you the control you need to produce X-ray quality welds in 3G and 4G positions.

Whether you are welding heavy structural beams, offshore platforms, or general fabrication projects, the MEGAFIL 713R adapts to your setup. It runs great on 100% CO2 for deep penetration and cost savings, or on an Argon mix for an even smoother arc and cleaner bead appearance. The .045" diameter is the perfect middle ground for bridging gaps and laying down heavy fill passes. Upgrade your welding game with a wire that feeds better, welds smoother, and protects against cracking.

Why Welders Prefer MEGAFIL 713R

• All-Position Control: Puddle stays where you put it, even overhead.
• Clean Welds: Low spatter and easy slag removal save cleanup time.
• Consistent Feeding: Copper coating and seamless tube shape reduce liner friction and tip wear.
• No Porosity: Hermetic seal keeps flux dry, preventing worm tracks and pinholes.
