TIG FILLER WIRE COMWELD LW1 1.6MM

TIG Filler Wire Comweld LW1 1.6mm

Premium Copper-Coated Mild Steel TIG Rod for Professional Welding

Comweld LW1 1.6mm is a copper-coated, double-deoxidised low carbon steel filler rod engineered for both oxy-acetylene (gas fusion) welding and Gas Tungsten Arc Welding (GTAW/TIG) of mild and medium-strength steels. Manufactured by CIGWELD (an ESAB brand), this trusted Australian welding consumable is a go-to choice for fabricators, boilermakers, and pipe welders who need consistent, defect-free welds.

Key Features

• Copper-coated finish – improves feedability, resists oxidation during storage, and enhances arc conductivity
• Double-deoxidised low carbon steel core – produces clean, sound welds with minimal porosity
• 1.6mm diameter – ideal for thin-to-medium gauge sheet, pipe, and plate welding
• AWS A5.2 classification: ER70S-4 – meets recognised industry standards for filler metal quality
• Smooth, consistent arc characteristics for precise, professional-grade weld beads

Applications

Comweld LW1 1.6mm is recommended for TIG welding steel pipes, plates, and castings in the 500 MPa tensile strength class. It's widely used across:

• General fabrication and maintenance welding
• Steel pipe and tube welding
• Structural steel plate work
• Workshop and on-site repair welding
• Light-to-medium industrial manufacturing

Why Choose Comweld LW1?

This filler wire is favoured by welders for its reliable arc stability, low spatter, and clean weld pool control — making it easier to produce strong, ductile welds even for less experienced operators. The copper coating also helps prevent rust and corrosion during storage, extending shelf life without compromising weld quality.
