E71T-11 Gasless Flux-Cored Welding Wire is a self-shielded, all-position flux-cored wire for gas-free welding of mild and low-carbon steel. Unlike single-pass-only wires, E71T-11 supports multi-pass welding across a wide range of thicknesses, making it a versatile choice for fabrication, repair, and general-purpose work — with no shielding-gas bottle required.
Key Features
No shielding gas required — DCEN (electrode-negative) straight polarity
Ideal for portable machines and outdoor/windy sites
Ideal Applications
General steel fabrication and non-critical structural repair
Multi-pass fillet and groove welds
Trailers, frames, railings, farm and ranch equipment
Maintenance and field repair
