T3327GL2 - CK Worldwide 3/32" Blue Tungsten Electrodes (10 Pack)

Premium Non-Radioactive TIG Welding Electrodes

The CK Worldwide T3327GL2 is a high-performance 2% Lanthanated tungsten electrode designed to meet the rigorous demands of modern industrial welding. Identified by its blue color code, this electrode falls under the AWS classification EWLa-2 (or WL20 in ISO standards). It is engineered with a composition of approximately 97.3% tungsten and 1.8% to 2.2% Lanthanum Oxide (La2O3). This specific formulation provides distinct metallurgical advantages, primarily by lowering the work function of the electrode, which facilitates easier electron emission compared to pure tungsten. The result is an electrode that offers exceptional arc starting capabilities, stable arc maintenance, and excellent reignition properties, making it a staple in professional fabrication shops.

One of the most significant advantages of the 2% Lanthanated tungsten is its non-radioactive nature. Historically, 2% Thoriated (Red) tungsten was the industry standard for DC welding, but it carries low-level radiation risks due to the Thorium content. The CK Blue Tungsten serves as a direct, safe replacement, offering similar—and often superior—conductivity and performance characteristics without the associated health hazards. This makes it particularly suitable for environments with strict safety protocols, such as nuclear, food and beverage, and pharmaceutical facility maintenance.

Versatility is a core strength of the T3327GL2. Unlike specialized electrodes that excel in only one polarity, 2% Lanthanated tungsten performs admirably in both Alternating Current (AC) and Direct Current (DC) applications. It is compatible with both older transformer-based machines and modern inverter power sources. When used on DC, it maintains a sharp point for deep penetration on carbon and stainless steels, nickel alloys, and titanium. On AC, it handles the balling necessary for aluminum and magnesium welding while maintaining better shape stability than pure tungsten. This 10-pack of 3/32" x 7" electrodes ensures you have a reliable supply of high-quality consumables for a wide range of welding tasks.
