The CHIYODA E71T-GS is a premium, high-efficiency self-shielded (gasless) flux-cored MIG welding wire engineered for operators who require maximum portability, ease of use, and versatility. Because this advanced wire contains its own specialized internal flux material to protect the molten pool, it completely eliminates the need for an external shielding gas tank (like CO2 or Argon).

Adhering to the AWS A5.20 E71T-GS specification, CHIYODA’s wire is the absolute "quality over quantity" benchmark for thin gauge metal fabrication. It is highly favored by mobile maintenance crews, home workshops, and automotive repair technicians because it runs beautifully on small, portable 230V inverter MIG machines, delivering structural bonds anywhere, anytime.

• 100% Gasless Portability: Requires zero external shielding gas bottles, regulators, or hoses—making your setup lightweight, compact, and ready for immediate mobile field deployment.

• Designed for Outdoor Environments: Traditional gas-shielded MIG welds are easily ruined by breeze or wind that blows the shielding gas away. The self-shielding properties of the E71T-GS mean your arc remains perfectly stable even in windy, outdoor conditions.

• Zero Burn-Through on Thin Gauges: Specifically formulated for single-pass fillet and lap welding on thin carbon or galvanized steels (down to 20 gauge) without the risk of burning through the metal.

• Cuts Through Dirty and Galvanized Steels: The aggressive deoxidizers built into the internal flux core easily bite through light rust, dirt, oil, mill scale, or zinc coatings, creating a strong weld without exhaustive surface preparation.

• Excellent Operator Appeal: Delivers a smooth arc action, minimal spatter, full slag coverage, and exceptionally easy slag removal for clean, square weld edges that reduce cleanup time.
