Tungsten electrodes are the core consumables for TIG (GTAW) and Plasma welding. We supply a full range of pure tungsten and alloyed tungsten electrodes in compliance with ISO 6848 / AWS A5.12 standards, including WT20, WC20, WL15, WL20, WY20, WP, and WZ8 types. Each type is color-coded for quick identification, ensuring welders select the right electrode for every application.
All electrodes are manufactured from high-purity tungsten raw material (99.95%), with precisely controlled doping elements to deliver stable arc ignition, low burn-off rate, and excellent weld quality across AC and DC welding operations.
