E70S230 - Harris ER70S-2 Carbon Steel TIG Welding Rod 1/16" x 36" (10 lb Tube)

Achieve Flawless Welds with Harris ER70S-2

When you are laying down a root pass on a critical pipe joint or fabricating sheet metal that needs to look as good as it holds, you can't afford porosity. The Harris ER70S-2 TIG Rod is the welder's choice for peace of mind. Known in the industry as a "triple deoxidized" rod, it contains a special blend of cleaning agents—Aluminum, Titanium, and Zirconium—that work tirelessly in your puddle to pull out impurities. This means that even if your metal prep isn't 100% perfect, or if you are dealing with some stubborn mill scale or rust, this rod fights back to give you a clean, solid bead.

Harris is a name synonymous with quality in the welding world, and their ER70S-2 rods live up to that reputation. The 1/16" diameter is incredibly versatile, giving you the fine control needed for delicate tubing or thin sheet metal, while still carrying enough metal for structural repairs. The rods feed smoothly and melt consistently, allowing you to focus on your torch angle and travel speed rather than fighting your filler metal.

This 10 lb tube is perfect for the shop or the rig, keeping your rods straight and dry until you're ready to burn them. Whether you are working on mild steel castings, structural frames, or high-pressure piping, this rod delivers the strength (78,000 psi tensile) and ductility you need. It flows wet and flat, tying into the toes of the weld effortlessly. Stop grinding out porosity and start laying down dimes with a rod designed to handle the reality of industrial welding.

Best Applications

Use this rod for everything from automotive exhaust repairs to heavy-duty structural steel. It is especially famous for being the "go-to" rod for the root pass on open-root pipe welds, where its ability to bridge gaps and resist suck-back ensures a solid foundation for your hot and fill passes.
