ER70S-2 TIG filler rod is a versatile choice for mild and carbon steels, especially when welding on surfaces with mill scale, rust, or oil. Its triple deoxidizers (Al, Ti, Zr) ensure smooth, clean welds even on less-than-perfect base metals, making it ideal for general fabrication, piping, and automotive repair.
Applications
✅ General fabrication of mild steel
✅ Ability to weld slightly rusty or contaminated steel
✅ Produces clean welds that require little or no post cleaning
✅ Lower tensile strength than ER70S-6
