WIA Austarc 77 E7018 Electrodes 3.2mm 5kg – 77/32

Professional Low Hydrogen Welding Electrode

The WIA Austarc 77 E7018 Electrode 77/32 delivers high-quality welding performance for demanding structural and fabrication applications. Designed as a low hydrogen iron powder electrode, it provides excellent weld strength, smooth arc stability, and reliable mechanical properties. The 3.2mm electrode size offers versatility across a wide range of heavy-duty welding tasks.

Smooth Arc and High-Quality Weld Finish

Austarc 77 electrodes produce a smooth and stable arc with minimal spatter during operation. The weld deposit delivers excellent edge wetting and clean bead appearance, helping reduce undercut and post-weld cleanup time. Slag removal remains easy, improving productivity and weld consistency across multiple passes.

Designed for Critical Welding Applications

These E7018 electrodes suit structural steel fabrication, pressure vessels, heavy machinery repairs, mining equipment, and maintenance work. The low hydrogen formulation helps reduce the risk of hydrogen cracking while delivering high ductility and strong impact resistance. Welds achieve x-ray quality results and maintain toughness at temperatures down to -50°C.

All Position Welding Capability

The Austarc 77 supports all positional welding except vertical down applications. It performs effectively on both AC and DC welding machines, offering flexibility for workshop and on-site environments. The stable arc characteristics also improve control during vertical-up welding tasks.

Reliable WIA Performance

Manufactured by WIA, the Austarc 77 range has built a strong reputation for consistent welding quality and dependable performance. Professional welders value these electrodes for their smooth operation, reliable restrike characteristics, and durable weld properties across demanding industrial applications. Community welding discussions also frequently reference 7018 rods for structural and repair work due to their low hydrogen properties and strength.
