Product Overview
Comweld LW1-6 (ER70S-6) is a premium copper-coated TIG welding filler rod engineered for high-quality, precision welds on carbon and low-alloy steels. With a diameter of 1.6mm, this filler wire is one of the most popular sizes for general fabrication, workshop, and industrial TIG welding applications, delivering smooth arc starts, excellent bead appearance, and minimal spatter.
Classified under AWS A5.18 ER70S-6, this filler wire is formulated with higher levels of silicon and manganese deoxidizers than standard ER70S-2 rods, making it ideal for welding steels with mill scale, rust, or light surface contamination — while still producing clean, X-ray quality welds.

Why Choose ER70S-6 Filler Wire?
ER70S-6 is the go-to choice for welders who need a forgiving, all-purpose filler wire that performs reliably even when base metal preparation isn't perfect. The added deoxidizers make it more tolerant of scale and light rust compared to ER70S-2, reducing porosity risk and giving welders confidence across a wide range of site and workshop conditions.
