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

CK Worldwide T187GT2 Red Tungsten Electrodes (10-Pack)

Elevate your TIG welding performance with the CK Worldwide T187GT2 2% Thoriated Tungsten Electrodes. Commonly referred to as "Red Tungsten" due to their color coding, these electrodes are a staple in the welding industry for DC applications. The 1/8-inch (3.2mm) diameter is a robust size, perfect for welding thicker sections of steel and stainless steel where higher heat input and amperage are required. This 10-pack ensures you have ample stock for continuous production or extensive fabrication projects.

Superior Arc Characteristics
The inclusion of 2% thorium oxide gives these electrodes distinct advantages over other tungsten types. The principal benefit is the lowered work function, which allows for effortless arc starts even at lower voltages. Once the arc is established, it remains incredibly stable, reducing the likelihood of arc wander which can lead to defects. Furthermore, thoriated tungsten has a higher melting point and greater resistance to contamination, meaning it is less likely to spit or degrade during the weld. This durability makes it a cost-effective choice for welders who demand longevity from their consumables.

Optimized for DC Applications
While modern inverters allow for various tungsten types, 2% Thoriated remains the preferred choice for DC Electrode Negative (DCEN) welding on materials such as carbon steel, 304/316 stainless steel, titanium, and nickel alloys. It is generally not recommended for AC welding of aluminum, as it does not ball up well and tends to split. For DC work, however, it holds a sharp point exceptionally well, allowing for deep penetration and precise heat control in the weld puddle.

Safety and Handling
Users should be aware that thoriated tungsten contains low-level radioactive material. However, it remains one of the most popular electrodes worldwide due to its performance. When grinding the tip to a point, it is important to use a dedicated grinder with dust collection or wear appropriate respiratory protection to avoid inhaling the dust. With proper handling, these electrodes offer unmatched performance for critical welding tasks.
