WG116X7 - Weldcraft Rare Earth Tungsten Electrodes, 1/16 in x 7 in, 10-Pack

Advanced Oxide Formulation for Precision Arc Control

The Weldcraft WG116X7 Rare Earth Tungsten Electrodes represent a significant advancement in TIG welding consumable technology. Engineered with a proprietary blend of rare earth oxides—including Cerium, Lanthanum, and Yttrium—these electrodes are designed to overcome the limitations of traditional binary tungsten alloys. The 1/16-inch (1.6mm) diameter provides optimal current carrying capacity for fine to medium-gauge fabrication, offering a stable arc column that resists wandering even at lower amperages. Unlike thoriated tungsten, which relies on radioactive thorium dioxide for electron emission, this rare earth blend achieves equal or superior work functions without the associated health risks, making it compliant with modern safety standards in strictly regulated industrial environments.

Technically, the presence of multiple oxides serves to lower the electron work function of the tungsten matrix, facilitating easier arc initiation and re-ignition. This is particularly critical in automated or repetitive manual welding cycles where ignition failure can lead to defects. The grain structure of the WG116X7 is optimized to reduce the rate of electrode erosion, maintaining the tip geometry for extended periods. This dimensional stability ensures consistent weld bead profiles and reduces the frequency of regrinding, thereby increasing overall process efficiency. The electrode is classified under the AWS A5.12 EWG standard, indicating a manufacturer-specific composition tailored for high performance.

The versatility of this electrode is a key technical asset. It is formulated to perform exceptionally well in both Direct Current (DC) applications for ferrous metals and Alternating Current (AC) applications for non-ferrous alloys like aluminum and magnesium. In AC welding, the electrode maintains a clean balled end without excessive spitting or splitting, which is often a failure mode in inferior substitutes. The 7-inch length is standard for industry torches, and the electrodes are precision-ground to ensure diameter consistency. For welding engineers and quality control specialists, the WG116X7 offers a reliable, high-purity solution that simplifies inventory by covering a broad spectrum of base materials including Carbon Steel, Stainless Steel, Nickel Alloys, Titanium, and Aluminum.
