ED561340 - E71T-11 Gasless Flux Core MIG Wire .035 Spool

High-Performance E71T-11 Self-Shielded MIG Wire

Maximize your welding efficiency with our .035" E71T-11 Gasless Flux Core Wire. This consumable is manufactured to meet strict AWS A5.20 standards, providing a tensile strength of at least 70,000 psi. It is specifically designed for the Flux Cored Arc Welding-Self Shielded (FCAW-S) process, utilizing a specialized internal flux composition that protects the molten weld pool from atmospheric contamination. This makes it the go-to solution for structural steel erection, bridge fabrication, and heavy equipment repair where dragging gas cylinders is impractical.

The wire operates on DC Electrode Negative (DCEN) polarity, also known as straight polarity. This setup directs the heat into the wire rather than the base metal, increasing the deposition rate and ensuring a smooth, stable arc. The .035" diameter offers a perfect balance between deposition rate and control, allowing for welding on thin gauge sheet metal as well as thicker plates up to 1/2 inch with proper technique and multi-pass layering. It offers excellent wetting action, ensuring good fusion at the toes of the weld and reducing the risk of cold lap.

Unlike E71T-GS, which is strictly for single-pass applications, E71T-11 is capable of multi-pass welding (within specific thickness limitations), offering greater structural integrity for more demanding projects. It performs admirably on galvanized steel, burning through the zinc coating while minimizing porosity. The fast-freezing slag system supports out-of-position welding, giving the operator excellent puddle control in vertical-up and overhead scenarios.

Technical Specifications & Usage

For optimal results, ensure your machine is set to DCEN. A knurled drive roll is recommended to feed the tubular wire without crushing it, ensuring consistent wire feed speeds and preventing bird-nesting. Stick-out (contact tip to work distance) should generally be maintained between 3/8" and 1/2" to preheat the wire properly and activate the flux.
