When your project demands more strength than a standard mild steel rod can provide, the Exocor ER80S-D2 TIG Rod is the professional's choice. This 3/32" filler metal is legendary among fabricators working with 4130 Chromoly tubing, making it a go-to consumable for motorsports, roll cage fabrication, and experimental aircraft frames. The "80S" in the name stands for a minimum tensile strength of 80,000 psi, giving you the confidence that your welds can handle extreme loads and stresses without failure.
What sets the ER80S-D2 apart is its specialized alloy blend. It contains Molybdenum, which boosts strength and hardness, and high levels of deoxidizers like Manganese and Silicon. For the welder, this translates to a puddle that wets out smoothly and fights off porosity, even if the metal isn't perfectly prepped. The 3/32" diameter is incredibly versatile, offering enough deposition for thicker wall tubing and plate while still being controllable at lower amperages for detail work. You'll notice a clean, fluid puddle that freezes predictably, allowing for that stack-of-dimes appearance that every TIG welder strives for.
This 10lb tube ensures you have plenty of material on hand for large projects or ongoing repair work. The 36-inch rods are stamped for easy identification, so you never mix up your filler metals. Whether you are repairing heavy equipment, building a custom chassis, or welding high-yield pipe, Exocor's ER80S-D2 delivers the performance, consistency, and strength required for critical welds. Pair it with 100% Argon shielding gas and a sharp thoriated or lanthanated tungsten for best results.
