E70S230 - Harris ER70S-2 1/16" TIG Welding Rod - 10lb Tube

Harris ER70S-2: The Problem Solver for Dirty Steel

When you are out in the field or working on a repair job where the metal isn't brand new, you need a TIG rod that is forgiving. The Harris® ER70S-2 1/16" Carbon Steel TIG Rod is exactly that tool. Known among professional welders as the "triple deoxidized" rod, it is formulated to handle the real-world conditions of welding. If you have ever struggled with porosity or pinholes when TIG welding mild steel that had a bit of rust or mill scale on it, switching to ER70S-2 can make a world of difference. The added deoxidizers in the wire act as cleaning agents in the puddle, pulling out impurities and leaving you with a smooth, solid bead.

This 10 lb box of 36-inch rods is a staple for any fabrication shop. While it is famous for its ability to handle dirty metal, it is also a precision instrument. It is widely used for roll cages, automotive chassis work, and critical pipe welding because it produces a puddle that is easy to control and wets out flat. The 1/16" diameter is versatile, perfect for thin sheet metal work but substantial enough to handle root passes on thicker tubing. It flows smoothly and freezes predictably, giving you the control you need to lay down those stack-of-dimes welds.

Don't let inferior filler metal compromise your project. The Harris ER70S-2 offers a tensile strength of 78,000 psi, ensuring that your welds aren't just pretty—they are strong. Whether you are fixing farm equipment, building a custom exhaust, or welding structural brackets, this rod gives you the confidence that your welds will hold. It works on all positions, so you can tackle vertical and overhead joints with the same ease as flat bench work.
