TTU938 - ER70S-2 Mild Steel TIG Welding Rod 3.2mm 1lb Tube

Reliable 3.2mm ER70S-2 TIG Rods for Tough Repair Jobs

Tackle your mild steel welding projects with confidence using our 1lb tube of ER70S-2 TIG Rods. Measuring 3.2mm (1/8") in diameter, these rods are the heavy-hitters for your shop's TIG setup, perfect for joining thicker steel plates, pipe, and structural components. The ER70S-2 classification is legendary among seasoned welders for its ability to handle "dirty" steel. If you are doing repair work where you can't grind every square inch of the metal to a shiny finish, this is the rod you want in your hand.

Unlike standard filler metals that might bubble up or leave pinholes when they hit a patch of rust or mill scale, the ER70S-2 is engineered with triple deoxidizers—Aluminum, Titanium, and Zirconium. These elements act like cleaning agents in your weld puddle, pulling out impurities and ensuring a solid, crack-free bead. It’s the forgiving nature of this rod that makes it a favorite for maintenance, repair, and operations (MRO) where real-world conditions aren't always pristine.

The convenient 1lb tube is perfect for the hobbyist, the mobile welder, or the shop that needs specific sizes on hand without stocking massive boxes. It keeps your rods clean, dry, and organized, preventing moisture absorption and contamination that can ruin a TIG weld. Whether you are fixing farm equipment, working on an automotive chassis, or fabricating custom brackets, these rods deliver professional results.

Don't let imperfect metal slow you down; grab a tube of ER70S-2 and get the job done right.
