WL2018X7 - Weldcraft 1/8" Blue Lanthanated Tungsten Electrodes (10-Pack)

Premium Non-Radioactive TIG Welding Electrodes

The Weldcraft WL2018X7 2% Lanthanated Tungsten Electrode is a high-performance consumable designed to meet the rigorous demands of modern TIG welding. Engineered with a composition of approximately 98% tungsten and 1.8% to 2.2% lanthanum oxide, this electrode offers a superior, non-radioactive alternative to traditional 2% Thoriated tungsten. The addition of lanthanum oxide significantly lowers the work function of the electrode, allowing it to start and maintain an arc with exceptional ease. This makes it a preferred choice for welders seeking reliable ignition and restrike capabilities without the safety concerns associated with radioactive isotopes.

One of the defining characteristics of the WL2018X7 is its incredible versatility. It is engineered to perform flawlessly in both Alternating Current (AC) and Direct Current (DC) welding processes. When used with AC, it maintains a stable balled end, making it excellent for welding aluminum and magnesium alloys. In DC applications, it holds a sharp point well, providing deep penetration and precise heat control for carbon steel, stainless steel, and titanium. This dual-capability allows fabrication shops to consolidate their inventory by using a single tungsten type for a wide variety of materials and power sources, including both advanced inverters and traditional transformer machines.

Durability is another key advantage of this Weldcraft electrode. The lanthanum content improves the electrode's ability to handle high amperage levels while minimizing the burn-off rate. This results in less tip erosion and longer intervals between regrinding, ultimately improving productivity and reducing downtime. Whether you are working on critical aerospace components, pressure vessels, or general industrial fabrication, the consistency of the arc provided by these 1/8-inch diameter electrodes ensures high-quality welds with minimal contamination. Each package contains ten 7-inch electrodes, color-coded blue for instant identification in your workshop.
