S249412-029 - Hobart FabCOR 86R .045 Metal Core Welding Wire 33lb Spool

High-Performance Metal Core Wire for Demanding Fabrication

The Hobart FabCOR 86R .045" Metal Core Welding Wire is a premium gas-shielded carbon steel tubular wire designed to excel in environments where surface conditions are less than perfect. Engineered with a specific formulation rich in deoxidizing elements, this wire offers exceptional tolerance for mill scale, rust, and other surface contaminants often found in heavy industrial applications. Unlike standard solid wires that may struggle with porosity or lack of fusion when welding over scaled plates, the FabCOR 86R ensures sound weld deposits with minimal pre-weld cleaning, significantly increasing throughput and productivity in fabrication shops.

This 33lb spool is optimized for the metal-cored arc welding (MCAW) process, delivering higher deposition rates and travel speeds compared to solid wires of the same diameter. The composite metal-cored structure allows for a broader, more fluid weld pool that bridges gaps effectively and wets out smoothly at the toes of the weld. This results in flat, aesthetically pleasing bead profiles that require little to no post-weld grinding. The wire is classified as E70C-6M H4, indicating its suitability for high-strength applications requiring consistent mechanical properties and low hydrogen content to prevent cracking.

Versatility is a key strength of the FabCOR 86R. It performs admirably in both single-pass and multi-pass applications, making it a go-to choice for industries ranging from railcar manufacturing to shipbuilding and general structural steel fabrication. The wire is designed to operate with Argon/CO2 shielding gas mixtures, providing a stable, low-spatter arc that reduces cleanup time and consumable waste. Whether used in semi-automatic handheld welding or integrated into robotic welding cells, the consistent feedability and arc performance of Hobart FabCOR 86R make it a reliable solution for maximizing welding efficiency.

By choosing Hobart's metal-cored technology, fabricators can leverage the benefits of slag-free welding associated with solid wire while enjoying the deposition benefits of flux-cored wires. The FabCOR 86R specifically targets the common pain point of mill scale, turning a challenging variable into a manageable aspect of the production line. This wire represents a balance of speed, quality, and forgiveness that is essential for modern, high-volume manufacturing environments.
