Product Overview

The CIGWELD Vertricor 81Ni1 MIG Wire (1.2mm, 15kg Spool) is a premium gas-shielded, nickel-alloyed solid MIG wire engineered for welding fine-grain, high-tensile steels. Classified under AWS A5.28 ER80S-Ni1, this low-alloy wire delivers exceptional weld metal toughness, making it the go-to choice for structural, mining, earthmoving, and heavy fabrication applications where impact strength at low temperatures is critical.

Manufactured by CIGWELD — a trusted name in Australian and global welding consumables — this wire is copper-coated for smooth feeding, consistent arc performance, and reduced downtime on the job.

Key Features

• Diameter: 1.2mm — ideal for medium-to-heavy gauge steel welding
• Spool Size: 15kg — reduces spool changeovers on long production runs
• Classification: AWS A5.28 ER80S-Ni1 / equivalent low-alloy nickel steel wire
• Nickel-Alloyed Composition: Enhances low-temperature impact toughness and crack resistance
• Copper-Coated Finish: Promotes smooth wire feeding and stable electrical contact
• High Weld Metal Strength: Suited to high-tensile and fine-grain structural steels
• Consistent Arc Stability: Minimizes spatter for cleaner welds and less post-weld cleanup

Typical Applications

• Structural steel fabrication
• Mining and earthmoving equipment repair
• Heavy vehicle and trailer manufacturing
• Pressure vessel and pipeline components
• General engineering requiring high-strength, low-temperature toughness welds

Why Choose CIGWELD Vertricor 81Ni1?

CIGWELD's Vertricor range is trusted by welders and fabricators across Australia and internationally for delivering reliable, X-ray quality welds with excellent mechanical properties. The 81Ni1 wire's nickel content specifically improves toughness in cold-climate or low-temperature service conditions, making it a preferred choice for critical structural applications where weld failure isn't an option.

The 15kg spool format is designed for industrial and workshop environments, offering better cost-per-kg value and fewer interruptions compared to smaller spool sizes — ideal for high-volume MIG welding operations.

Recommended Shielding Gas

Typically used with Argon/CO2 mixed shielding gas blends (commonly 80/20 or similar) for optimal arc stability and weld pool control, though exact gas mix may vary based on application and base metal thickness.
