Flux Cored Welding (FCW) Wires

TOKO E71T-GS — Self-Shielded Flux-Cored Wire

TOKO E71T-GS is a self-shielding, all-position flux-cored welding wire designed for single-pass applications. It requires no external shielding gas, making it ideal for field welding and outdoor environments where gas shielding is impractical.

Key Specifications:

AWS Standard: A5.20 E71T-GS
Shielding: Self-shielded (gasless)
Polarity: DC straight polarity — minimizes burn-through risk
Position: All-position

Applications: Lap and fillet welds on thin mild and galvanized steels; agriculture, construction, and production.

Key Advantage: Excellent on thin materials with minimal risk of burn-through — perfect for 240V MIG machines and general-purpose welding.
