MIG WIRE CIGWELD AUTOCRAFT LW1 S4 0.9MM 15KG

Product Overview

The CIGWELD Autocraft LW1-S4 MIG Wire (0.9mm, 15kg) is a premium copper-coated solid welding wire engineered for high-performance MIG/MAG welding of mild and low-alloy steels. Trusted by professional welders, fabricators, and industrial workshops across Australia, this wire delivers consistent arc stability, low spatter, and smooth, uniform weld beads for a wide range of structural and general fabrication applications.

Manufactured to AS/NZS ISO 14341-B G4Si1 (equivalent to AWS ER70S-6) standards, Autocraft LW1-S4 is formulated with higher levels of silicon and manganese deoxidizers, making it ideal for welding over mill scale, light rust, and oil residue commonly found on hot-rolled and cold-rolled steel.

Key Features

• Diameter: 0.9mm — suited for a broad range of material thicknesses
• Spool Weight: 15kg — ideal for extended production runs, reducing downtime for wire changes
• Classification: AS/NZS ISO 14341-B G4Si1 / AWS A5.18 ER70S-6
• Copper-Coated Finish: Enhances electrical conductivity and protects against oxidation during storage
• High Silicon-Manganese Content: Superior tolerance to surface contaminants like mill scale and rust
• Smooth Wire Feeding: Precision-wound layers minimize birdnesting and feed interruptions
• Low Spatter Levels: Reduces post-weld cleanup and improves productivity
• Excellent Bead Appearance: Produces clean, uniform weld profiles with good tie-in and wetting action

Applications

Ideal for MIG welding of:

• Mild steel and carbon steel fabrication
• Structural steel and general engineering
• Automotive panel and chassis repair
• Sheet metal work
• Workshop, maintenance, and repair welding
• Manufacturing and production welding environments

Compatible with shielding gases including CO2 and Argon/CO2 mixed gas blends (e.g., 80/20 Ar/CO2), depending on desired penetration and bead characteristics.
