E71T-GS Gasless Flux-Cored Welding Wire is a self-shielded, single-pass flux-cored wire built for fast, gas-free welding of thin mild and low-carbon steel. Because it runs without external shielding gas, it is ideal for portable wire-feed machines and outdoor or windy job sites where bottled gas is impractical.
Key Features
No shielding gas required — runs on DCEN (electrode-negative) straight polarity
Smooth arc with good wetting on thin-gauge steel
Easy slag removal and a clean, flat bead
Great match for portable and entry-level welders
Performs well outdoors and in breezy conditions
Ideal Applications
Single-pass welds on 18-gauge to 1/4 in. mild steel
Lap, fillet, and butt joints
Auto body, trailers, fencing, brackets, and general repair
DIY, hobby, farm, and maintenance work
