Filler Rod ER70S-2 1/16 10LB

The Filler Rod ER70S-2 1/16 10LB from Eastwood is a premium mild steel welding rod engineered for critical marine and boating repairs where structural integrity and corrosion resistance demand uncompromising quality. Built for welders who understand that a strong weld joint is non-negotiable—whether you're repairing hull damage, reinforcing transom brackets, or fabricating custom aluminum-friendly connections on deck. This rod is the choice of serious boat builders and restoration professionals who depend on reliable, consistent welds in saltwater and freshwater environments.

The ER70S-2 classification indicates a solid wire rod with a 1/16-inch diameter, designed for use with MIG (gas metal arc) welding equipment and suitable for joining mild and low-carbon steels. The 10-pound spool delivers adequate material for medium-scale repairs and fabrication work without requiring frequent changeovers on the water or in the shop. ER70S-2 formulation produces minimal spatter and excellent bead appearance, critical when working on visible marine components where appearance and performance must coexist. The rod's deoxidizers ensure clean, strong welds even on mill-scale or lightly oxidized surfaces—a reality when working with salvaged marine steel or aged hull sections.

Boaters, marine fabricators, and aluminum-boat owners benefit most from this rod when performing structural work that standard hardware cannot address. The ER70S-2 1/16 10LB pairs seamlessly with standard MIG welders operating at recommended voltage and wire-feed speeds for this diameter and rod classification. Success depends on proper gas selection—CO2 or argon/CO2 blend—and consistent technique, making this rod ideal for those with intermediate to advanced welding experience. Store in a dry environment and keep the spool sealed between sessions to prevent moisture absorption, which degrades arc quality and weld integrity on critical marine applications.
