Mild Steel Flux Cored Wire - E71T-11
E71T-11 self-shielded flux-cored wire is a true gasless FCAW wire (AWS A5.20) that makes its own shielding as the flux burns — no gas bottle required. All-position and multi-pass rated, it runs on DC− (DCEN) for portable, outdoor, and general-purpose welding where a shielding-gas setup isn't practical. Common sizes .030", .035".

Frequently Asked Questions
Does E71T-11 need gas?
No. E71T-11 is self-shielded and runs on DC− (DCEN) — ideal for portable machines and outdoor work where wind would blow away shielding gas.
E71T-11 vs E71T-GS?
Both are gasless. E71T-GS is for single-pass welds on thinner material; E71T-11 is rated for multi-pass welding and handles a wider thickness range.
