ED034097 - Lincoln ER100S-1 High-Strength TIG Rod 3/32" (10lb Tube)

Tackle High-Strength Jobs with Lincoln ER100S-1

When your project demands more than just a standard mild steel rod, the Lincoln ER100S-1 TIG rod is the heavy-hitter you need in your arsenal. Designed for the serious fabricator working on high-yield steels, this rod is the go-to solution for welding HY-80, HSLA-80, and other robust materials used in heavy machinery, construction equipment, and specialized structural work. If you are repairing a crane boom or fabricating heavy-duty chassis components, this is the rod that ensures your welds hold up under pressure.

The 3/32" diameter offers excellent versatility, allowing you to manage heat input effectively while laying down a bead that looks as good as it performs. Lincoln Electric has formulated this wire with a mix of nickel, molybdenum, and manganese to give you a puddle that wets out smoothly and freezes with the toughness required for 100,000 psi tensile applications. You get the control you expect from TIG welding combined with the metallurgical muscle needed for critical joints.

Packaged in a durable 10lb tube, these 36-inch rods stay clean and straight until you are ready to burn them. The clean finish on the wire means you won't be fighting arc wander or contamination issues—just smooth, consistent feeding and a stable arc. Whether you are in the shop or out in the field, having a tube of ER100S-1 means you are ready for the tough jobs that demand high-strength specifications.

Don't compromise on structural integrity. Upgrade your filler metal to match the steel you are welding. With Lincoln's ER100S-1, you get professional-grade reliability that helps you pass inspections and deliver superior results every time you strike an arc.
