71315B - Hobart MEGAFIL 713R .045 Seamless E71T-1 Flux Core Wire

Hobart MEGAFIL 713R: Premium Seamless Flux Core Wire

The Hobart MEGAFIL 713R .045 Seamless Flux Core Wire represents the pinnacle of flux-cored arc welding (FCAW) technology. Designed for the most demanding industrial environments, this wire features a unique seamless manufacturing process. Unlike traditional folded wires, the MEGAFIL 713R is hermetically sealed and copper-coated. This design completely eliminates moisture absorption from the atmosphere, ensuring extremely low diffusible hydrogen levels (typically under 4ml/100g). For fabricators in the offshore, pipeline, and heavy structural steel sectors, this translates to superior resistance against hydrogen-induced cracking (cold cracking), even in high-humidity climates.

This rutile-based wire is engineered for versatility and performance. It operates effectively with both 100% Carbon Dioxide (CO2) and Argon/CO2 mixed gases (75-80% Ar), providing flexibility depending on gas availability and desired arc characteristics. The 35lb spool size is optimized for industrial wire feeders, reducing changeover downtime in high-volume production settings. Its mechanical properties meet stringent AWS requirements, making it a reliable choice for code-quality work where structural integrity is non-negotiable.

The MEGAFIL 713R is an all-position wire, thanks to its fast-freezing slag system. This allows operators to weld vertically up or overhead with ease, maintaining a flat bead profile and excellent tie-in. The seamless nature also improves current transfer and wire feedability, reducing contact tip wear and ensuring stable arc performance during extended welding sessions. Whether used in automatic, mechanized, or manual applications, this wire delivers consistent, high-quality deposition.
