EX100S1-093T - ER100S-1 High Strength TIG Welding Rod 3/32" (2.5mm)

Heavy-Duty Welding Power: ER100S-1 TIG Rod

When you are welding high-strength steel, you can't just grab any filler rod off the shelf. You need a consumable that hits as hard as the base metal. That's where the Exocor ER100S-1 TIG rod comes in. This 2.5mm (3/32") rod is built for the tough jobs—specifically designed to weld high-yield steels like HY-80 and HSLA-80. If you are working on heavy machinery, crane booms, structural supports, or pressure vessels that demand 100,000+ psi tensile strength, this is the rod you need in your torch.

What makes this rod special? It's the "special sauce" of Nickel and Molybdenum in the alloy. This blend doesn't just give you raw strength; it gives you toughness. Welds made with ER100S-1 resist cracking and hold up under stress, even in colder environments where standard mild steel rods might fail. It flows smoothly, giving you that classic TIG stack-of-dimes look while ensuring the metal underneath is solid as a rock.

Why Welders Choose This Rod:

• Matches High-Strength Steel: Perfect for HY-80 and HSLA-80 grades found in heavy fabrication.
• Crack Resistant: The Ni-Mo alloy helps prevent failure in highly stressed joints.
• Clean Burns: High-quality manufacturing means fewer impurities and a stable arc.
• Versatile Size: The 2.5mm diameter is a great all-rounder for root passes on pipe or multi-pass structural welds.

Whether you are repairing heavy earth-moving equipment or fabricating custom structural components, the ER100S-1 gives you the confidence that your welds will pass inspection and stand the test of time. Use it with straight Argon for the best results and clean your base metal thoroughly to get the most out of this high-performance alloy.
