Why Choose ER70S-6 TIG Wire?
The ER70S-6 classification features a higher silicon and manganese content than standard ER70S-2 wires, giving it enhanced deoxidizing properties. This makes the LW1-6 rod especially effective when welding steel with mill scale, light rust, or surface oxidation, producing cleaner welds with reduced porosity even under less-than-ideal base metal conditions.
Features & Benefits
- Smooth, Stable Arc Characteristics – Consistent feeding and arc stability for precise weld puddle control
- Excellent Bead Wetting & Profile – Produces flat-to-slightly-convex beads with minimal spatter
- High Silicon/Manganese Content – Superior deoxidization for welding on scaled or mildly contaminated surfaces
- Copper Coating – Improves electrical conductivity and provides corrosion resistance during storage
- Strong Mechanical Properties – High tensile strength welds suitable for structural and general fabrication work
- Versatile Application Range – Compatible with a broad range of mild and carbon steel grades
Recommended Applications
- General fabrication and structural steel welding
