T187GT2 - CK 2% Thoriated Red Tungsten 1/8 Inch 10-Pack

Premium 2% Thoriated Tungsten for Professional TIG Welding

The CK Worldwide T187GT2 2% Thoriated Tungsten Electrodes are the industry standard for Direct Current (DC) TIG welding applications. Identified by their red color code, these electrodes contain a precise blend of 97.3% tungsten and 1.7% to 2.2% thorium oxide. This specific composition, known as EWTh-2 or WT20, is renowned for its exceptional electron emission qualities, which translates to easier arc starting and a more stable arc during operation. For professional fabricators working with ferrous metals, thoriated tungsten remains a top choice due to its reliability and performance consistency.

These 1/8-inch diameter electrodes are designed to handle medium to high amperage ranges, making them versatile for a variety of material thicknesses. The addition of thorium oxide significantly increases the current-carrying capacity of the electrode compared to pure tungsten, while simultaneously reducing the rate of erosion. This means the electrode maintains its ground point longer, reducing the frequency of re-grinding and downtime. The 7-inch length is the standard size for most TIG torches, ensuring compatibility with your existing equipment setup.

Thoriated tungsten is specifically engineered for DC welding on non-corroding steels, titanium alloys, nickel alloys, and copper alloys. It provides a crisp, stable arc that is essential for high-quality welds on carbon and stainless steel. While thoriated tungsten is slightly radioactive, it is safe when handled according to standard safety protocols, particularly during grinding where dust extraction is recommended. The CK Worldwide manufacturing process ensures a consistent distribution of oxides throughout the rod, preventing wandering arcs and ensuring a premium weld bead profile.

This package contains 10 ground-finish electrodes, providing a durable supply for your workshop. Whether you are welding critical pipe joints, structural steel, or precision stainless components, the CK T187GT2 electrodes deliver the control and longevity required for industrial applications. Trust in the quality of CK Worldwide to provide consumables that help you achieve defect-free welds with excellent aesthetic appeal.
