Industrial Flux-Cored Welding Wires

Why Welders in Extreme Conditions Choose Our Wires

When you’re 300 feet up a wind turbine in the North Sea or repairing a mining truck in the Australian Outback, gas cylinders aren’t an option. That’s why our flux-cored wires are the secret weapon of field crews and heavy manufacturers. Engineered for high deposition rates, deep penetration, and zero gas dependency, these wires laugh at wind, rain, and thick rust. From shipyards in Korea to pipeline teams in Alberta, they’re built for jobs where failure isn’t an option.

Features That Outwork the Competition

Gasless, Not Clueless: Self-shielded design eliminates gas tanks—ideal for bridges, offshore rigs, or tight spaces. (A Texas crew welded 1,200ft of handrail in 40mph winds using these.)
Rust? Burn It Off: Silica-manganese flux eats through mill scale and light rust. No pre-cleaning needed.
X-Ray Quality, Every Time: Slag peels off like banana skin, revealing smooth beads that pass ASME Section IX inspections.
Certified Tough: AWS A5.20 E71T-1 & E71T-12 compliant.
Feed Smooth or It’s Free: Precision winding tested at 15m/min feed speed.

Grades & Applications:

E71T-1: All-position workhorse. Used to weld 50mm thick crusher jaws in Chilean copper mines.
E71T-12: Low-hydrogen variant for critical structural joints. Prevents cracks in -29°C Siberian pipelines.
E71T-GS: General purpose, perfect for farm equipment repairs.

Technical Parameters:

Diameter: 0.9mm (thin sheets), 1.2mm (most versatile), 1.6mm (heavy plate).
Spool Sizes: 5kg (portable), 15kg (high-volume), 300mm steel cores.
Tensile Strength: 550-670 MPa (AWS A5.20 verified).
Deposition Rate: 8-12 lbs/hr (30% faster than stick electrodes).
