When you are under the hood and the fit-up isn't perfect, or the steel isn't as clean as you'd like, you need a filler metal that forgives. The Harris ER70S-2 Mild Steel TIG Rod (3.2mm / 1/8") is built exactly for those real-world scenarios. Known among professional welders as the "go-to" rod for pipe root passes and general fabrication, the ER70S-2 formula includes extra deoxidizers that help pull impurities out of your puddle. This means you get fewer pinholes, less porosity, and a smoother bead, even if you are welding over a bit of rust or mill scale.
This 10lb tube of 1/8" rods provides a substantial supply for larger projects or busy shops. The 3.2mm diameter is perfect for filling gaps in thicker plate or laying down significant metal in multi-pass welds. Welders appreciate the way Harris rods feed; they are stiff enough to manipulate easily without being brittle, and the copper coating ensures they slide through your gloved fingers smoothly while making excellent electrical contact. Whether you are welding on an automotive chassis, repairing farm equipment, or laying a critical root bead on a pressure pipe, this rod gives you the control you need to produce a stack of dimes that looks as good as it holds.
Choosing Harris means choosing consistency. You don't have to worry about inconsistent chemistry from batch to batch. These rods flow wet and fast, allowing you to travel at a comfortable speed while ensuring good fusion at the toes of the weld. The resulting slag islands are small and easily brushed away, leaving a clean, shiny weld that is ready for inspection or painting. Stop fighting your puddle and start welding with confidence using the industry-proven performance of Harris ER70S-2.
