OVERVIEW

Hobart Megafil 713R: Premium Seamless Flux-Cored Wire for Industrial Fabrication

Josef Gas is proud to supply the Hobart Megafil 713R, a high-performance 1/16-inch (1.6mm) flux-cored welding wire designed for the most demanding carbon steel applications. This 35lb spool features Hobart's advanced seamless technology, which sets it apart from traditional folded wires. The manufacturing process creates a hermetically sealed, copper-coated tube that completely protects the flux core from the atmosphere. For industrial shops and large-scale fabricators, this means the wire is highly resistant to moisture absorption, ensuring low diffusible hydrogen levels (typically below 4ml/100g) directly from the package without the need for rigorous conditioning or heated storage.

The Megafil 713R is engineered for versatility and efficiency. It operates with a fast-freezing rutile slag system, making it an exceptional choice for all-position welding, including vertical-up and overhead. Whether you are welding structural steel beams, offshore platforms, or heavy machinery, this wire delivers consistent mechanical properties and excellent impact toughness even at low temperatures. It is compatible with both 100% Carbon Dioxide (CO2) and Argon/CO2 mixed gases, allowing you to utilize your existing gas supply setup from Josef Gas efficiently.

One of the key benefits for production environments is the wire's feedability. The copper coating and seamless surface provide smooth, friction-free feeding through liners and contact tips, significantly reducing wear and downtime associated with tip burn-back or bird-nesting. This makes the Megafil 713R a top contender for mechanized and robotic welding cells where reliability is paramount. By choosing this premium consumable, you ensure high-quality welds with excellent bead appearance and minimal spatter, reducing post-weld cleaning time and increasing overall throughput.

FAQ

This wire is designed to operate with either 100% CO2 or a mixture of 75-80% Argon and balance CO2. Using mixed gas typically provides a smoother arc and less spatter.

The seamless design hermetically seals the flux inside a copper-coated tube. This prevents moisture absorption, ensures low hydrogen levels (<4ml/100g), and improves feedability and shelf life compared to folded wires.

Yes, the Megafil 713R features a fast-freezing rutile slag system that makes it excellent for all-position welding, including vertical-up and overhead.

This specific product is 1/16 inch in diameter, which is approximately 1.6mm.

Due to its seamless, hermetically sealed nature, Megafil 713R is much more resistant to moisture pickup than standard flux-cored wires and does not typically require heated storage if kept in its original packaging.

This wire is designed to be welded using Direct Current Electrode Positive (DCEP).

Absolutely. The copper coating and seamless construction provide excellent stiffness and current transfer, ensuring consistent feeding and tip life essential for automation.

It is classified as E71T-1M H4 and E71T-1C H4, indicating it meets standards for tensile strength, all-position capability, and low hydrogen with both mixed gas and CO2.
