S308037-017 - Hobart ER70S-2 Carbon Steel TIG Rod 3/32" (1 lb Tube)

Hobart ER70S-2 TIG Rod - 3/32" x 36"

Get the job done right with Hobart ER70S-2 TIG welding rods, the go-to filler metal for welders tackling carbon steel projects that demand high strength and clean deposits. This 1 lb tube of 3/32" rods is perfect for your shop, garage, or service truck, keeping your consumables clean and organized until you're ready to strike an arc. The "S-2" classification stands out from standard mild steel rods because of its powerful deoxidizing package. If you've ever had to weld over steel that wasn't perfectly prepped—maybe it had a bit of rust, mill scale, or primer residue—you know how easily porosity can ruin a weld. These rods are formulated to fight that porosity, pulling impurities out of the puddle to leave you with a solid, sound bead.

Welders love the way Hobart ER70S-2 runs. It offers a crisp, stable arc and a puddle that wets out beautifully at the edges. This makes it much easier to control your travel speed and filler addition, resulting in those stack-of-dimes welds that look as good as they hold. It is an excellent choice for root passes on pipe or tubing, where getting full penetration without defects is critical. Because it flows so well, it's also forgiving for less experienced TIG welders who are learning to manage the heat and filler simultaneously.

This product comes in a convenient 1 lb plastic tube, which protects the rods from atmospheric moisture and oxidation during storage. No more loose rods rolling around your bench or getting bent in your toolbox. Whether you are fixing a roll cage, fabricating a custom bracket, or performing critical pipe repairs, Hobart ER70S-2 gives you the confidence that your filler metal is up to the task. Compatible with 100% Argon shielding gas and DCEN (straight polarity) setups, this is a versatile essential for any TIG setup.
