Mig Wire Flux Corded E71t_11 1,2mm 15kg Spool Gasless

The E71T-11 Gasless Flux-Cored Wire is a premium, industrial-grade welding electrode engineered for the demanding South African mining, agricultural, and outdoor construction sectors. Unlike solid wires, this 1.2mm "self-shielded" wire contains an internal flux core that generates its own protective gas shield as it melts. It is the primary choice for onsite repairs where carrying heavy gas cylinders is impractical or where high winds would blow away traditional shielding gas, making it the "go-to" wire for structural field work.

Key Performance Features

• No Shielding Gas Required: Specifically formulated for "Gasless" operation, eliminating the need for Argon/CO2 cylinders, regulators, and hoses.
• Superior Wind Resistance: The internal flux core provides a robust shield that is not easily disrupted by outdoor drafts, ensuring consistent weld quality on high-rise sites or open farm fields.
• High-Strength E71T-11 Classification: Designed for single or multi-pass welding on mild steel, providing a stable arc and excellent mechanical properties for structural applications.
• DCEN (Straight Polarity) Optimization: Engineered to run on Direct Current Electrode Negative, which concentrates heat on the wire for high deposition rates and deep penetration into thick sections.

Ideal Applications

• On-Farm Maintenance & Repair: Perfect for repairing heavy-duty ploughs, tractor frames, and livestock handling equipment in remote areas without gas access.
• Heavy Structural Construction: The industry standard for onsite welding of I-beams, trusses, and industrial carports where wind interference is a constant factor.
• Mining & Earthmoving Equipment: Ideal for the maintenance of buckets, chassis components, and specialized underground infrastructure where portability is key.
• Galvanized Steel Fabrication: Effectively "burns through" light surface contamination and galvanized coatings better than standard solid wires, making it ideal for fencing and gate repairs.

Product Benefits

• Rapid Deposition Rate: The 1.2mm diameter allows for fast metal transfer, enabling the operator to complete heavy-duty structural joints in fewer passes.
• Minimal Post-Weld Cleanup: Produces a thin, easily removable slag layer that protects the cooling weld bead, leaving a professional, rippled finish.
• All-Position Capability: Despite its high-deposition rate, the flux chemistry allows for effective welding in all positions, including vertical-up and overhead.

Pro Tip: When switching from solid wire to E71T-11 gasless wire, remember to reverse your machine's polarity to DCEN (Electrode Negative). For 1.2mm wire, use a "knurled" drive roll to ensure a steady feed without crushing the hollow wire. Always maintain a slightly longer "stick-out" (15mm – 20mm) than you would with solid wire to allow the flux to pre-heat for a smoother arc.
