Tig Welding Wire rod - ER70S-2
ER70S-2 TIG welding rod is a premium triple-deoxidized mild steel GTAW filler (AWS A5.18) containing zirconium, titanium, and aluminum deoxidizers. That chemistry produces exceptionally clean, porosity-free 70,000 psi welds even over light rust and scale — the preferred rod for X-ray-quality pipe root passes and out-of-position work. 36" cut lengths in 1/16", 3/32", and 1/8".

Frequently Asked Questions
Why choose ER70S-2 over ER70S-6?
ER70S-2 is triple-deoxidized, so it lays down cleaner, more porosity-free welds on rusty or scaled steel. It's the go-to for X-ray pipe root passes and critical out-of-position GTAW.
What amperage for ER70S-2 TIG rod?
As a guide: 70–110 A for 1/16", 100–160 A for 3/32", 120–210 A for 1/8", on 100% argon DCEN.
