WL2040X7 - Weldcraft 0.040 Blue Tungsten Electrodes (10-Pack)

Premium TIG Welding with Weldcraft 2% Lanthanated Tungsten

The Weldcraft WL2040X7 2% Lanthanated Tungsten Electrodes represent the pinnacle of non-radioactive TIG welding technology. Designed as a direct, high-performance substitute for traditional 2% Thoriated tungsten, these electrodes offer welders a safer working environment without sacrificing arc quality. The 0.040-inch (1.0 mm) diameter is specifically engineered for precision applications, making it the ideal choice for welding thin-gauge materials where heat control and arc stability are paramount. Each package contains ten 7-inch electrodes, color-coded blue for easy identification in the shop environment.

One of the standout features of the Weldcraft 2% Lanthanated series is its incredible versatility. Unlike pure tungsten which is limited to AC, or thoriated which is primarily DC, this lanthanated blend excels in both Alternating Current (AC) and Direct Current (DC) welding processes. This dual capability allows fabricators to switch between materials like aluminum, magnesium, carbon steel, and stainless steel without changing their electrode type. The addition of 1.8% to 2.2% Lanthanum oxide enhances the electrode's electron emission capabilities, resulting in easier arc starting and a stable arc that maintains its focus even at varying amperages.

Durability is a key factor in industrial MRO and fabrication, and the WL2040X7 delivers exceptional longevity. The specific oxide formulation reduces the burn-off rate, meaning the tip retains its geometry longer than 1.5% lanthanated or ceriated alternatives. This resistance to tip erosion translates to less downtime spent regrinding electrodes and more time welding. Whether you are working on aerospace components, automotive exhaust systems, or general precision fabrication, these electrodes provide the consistency required for X-ray quality welds. The manufacturing process ensures that the lanthanum is evenly distributed throughout the entire length of the tungsten, preventing the "wandering arc" issues often associated with lower-quality electrodes.

For shops looking to standardize their consumables, the Weldcraft 2% Lanthanated tungsten is a smart choice. It covers the widest range of applications and materials, reducing the need to stock multiple types of tungsten. Its ability to handle high amperage loads while maintaining a sharp point makes it a favorite among professional TIG welders who demand reliability and safety in their consumables.
