WIA AUSTARC 16TC 2.5mm Low Hydrogen Stick Electrodes 2.5kg – Premium Welding Solution

Product Description

AUSTARC 16TC is a high-performance low hydrogen stick electrode engineered for precision welding across diverse applications. Its unique twin coating extrusion process concentrates arc-stabilizing elements in the inner layer, ensuring exceptional arc control and stability with AC/DC power sources. Designed for all positional welding (except vertical down), this electrode delivers X-ray quality welds with reliable notch toughness down to -40¡ãC, making it ideal for critical structural and sub-zero temperature projects.

Core Features & Benefits

Applications

• Sub-zero temperature welding operations
• Structural steel fabrication
• Unknown composition steel welding
• Single-sided weld joints
• Pipe welding and maintenance
• Highly restrained joint assembly
• Buffer layers for hard surfacing

Performance Highlights

The electrode’s fluid slag action ensures excellent bead appearance while minimizing spatter. Its low hydrogen content (<8ml/100g) prevents porosity, making it suitable for high-stress applications. The consistent arc behavior reduces operator fatigue, increasing productivity for both experienced welders and technical professionals.

Quality Assurance

Manufactured in New Zealand using advanced extrusion technology, AUSTARC 16TC adheres to strict quality protocols. Each batch undergoes rigorous testing to ensure compliance with international welding standards, guaranteeing consistent performance and reliability.

Differentiation

Unlike conventional low hydrogen electrodes, the twin coating system provides superior arc initiation and stability across all current types. This technology delivers more precise heat control, resulting in better fusion and reduced post-weld distortion ¨C critical advantages for complex welding projects.
