64022400 - 2% Thoriated Tungsten Electrodes 3/32" x 7" (Red) - 10 Pack

The Classic Red Tungsten: 2% Thoriated 3/32"

If you have been TIG welding for any length of time, you know the "Red Tungsten." It is the legendary workhorse of the TIG welding world and for good reason. Our 2% Thoriated Tungsten electrodes (3/32" diameter) are designed to give you that crisp, stable arc you rely on for welding mild steel and stainless steel. Whether you are building a roll cage, welding exhaust piping, or doing precision fabrication work, this tungsten delivers the performance professional welders expect.

Why do welders love Red Tungsten? It's all about the point. Thoriated electrodes are famous for holding a sharp grind longer than almost any other type. This means you spend more time under the hood laying dimes and less time at the grinder. The 2% thorium oxide additive helps the electrode start an arc effortlessly—even at lower amperages—and prevents the tip from balling up or spitting when you crank up the heat on DC. This 3/32" size is the perfect "do-it-all" thickness, handling everything from delicate 1/16" sheet to heavier brackets and mounts.

Performance Tips:

• Grinding: Always grind your tungsten lengthwise (parallel to the rod) to ensure a focused arc. A tapered point is best for this electrode.
• Polarity: Strictly for DCEN (Direct Current Electrode Negative). Do not use this on AC for aluminum; it will not ball correctly and can split.
• Safety: Because thorium is slightly radioactive, always wear a respirator when grinding and wash your hands afterwards. If you prefer a non-radioactive alternative with similar performance, check out our Lanthanated (Blue/Gold) or E3 (Purple) options.

Equip your torch with the industry standard. These 7-inch electrodes fit all standard TIG torches (WP-17, WP-26, WP-9, WP-20) and come in a protective case to keep them straight and dry.
