LINCOLN® ER70S-2 - 3/32 IN (2.4 MM) - 10 LB CARTON (4.5KG)
LINCOLN® ER70S-2 TIG Welding Rod – 3/32" (2.4mm) – 10 lb (4.5kg) Carton
The Lincoln Electric ER70S-2 TIG welding rod in 3/32 inch (2.4mm) diameter is a premium-quality filler metal engineered for precision welding on carbon steels and low-alloy steels. Supplied in a convenient 10 lb (4.5kg) carton, this versatile rod is designed to deliver clean, high-quality welds with excellent mechanical properties, making it a top choice for professional fabricators, maintenance teams, and pipeline welders.
Product Overview
The ER70S-2 classification indicates a triple-deoxidized mild steel TIG rod containing aluminum, zirconium, and titanium. These added elements help eliminate porosity by effectively scavenging oxygen and impurities during welding, making it ideal for welding on dirty, rusty, or mill-scale steel surfaces where preparation may be limited.
Key Features & Benefits

Why Choose ER70S-2 TIG Rods?
Compared to other mild steel fillers like ER70S-6, ER70S-2 excels in situations where base metal cleanliness is less than ideal. Its enhanced deoxidizers provide greater tolerance to surface contaminants, making it a reliable option for fieldwork and repair jobs where perfect prep isn’t always possible.
Packaging & Handling
Supplied in a durable 10 lb carton, these rods are protected for transport and storage. For best performance, store in a dry, moisture-free environment to maintain weld integrity.
Boost Your Welding Performance
Whether you're tackling precision TIG welds or challenging repair work, the Lincoln Electric ER70S-2 3/32” TIG rod delivers consistent, high-quality results every time. Its versatility and reliability make it an essential addition to any professional welding setup.
