Lincoln Electric ER70S-6 TIG Rod | 3/32" x 36" | 5lb | ED034335
Lincoln ElectricLincoln Electric ED034335 ER70S-6 TIG Welding Rod – Smooth Bead, Strong Welds on Mild and Contaminated Steel
Lincoln Electric ER70S-6 TIG welding rod is engineered with elevated levels of silicon and manganese, making it the top choice for TIG welding mild steel—even when working with slightly rusted, oily, or contaminated base materials. This high-deoxidizer formulation enhances puddle fluidity and provides superior wetting action, resulting in smooth, even beads with minimal post-weld cleanup.
Ideal for structural steel, sheet metal, fabrication work, and repair jobs, ER70S-6 is a versatile filler metal that provides consistent performance across flat, horizontal, overhead, and vertical weld positions. Ink jet printing along the full length of the rod ensures easy identification, while Q2 Lot certification provides full traceability and deposit chemistry data per batch.
