BWS187GE3 - E3 Purple Rare Earth Tungsten Electrodes 1/8" x 7" (10-Pack)

Advanced Non-Radioactive TIG Welding Electrodes

The Best Welds E3 Purple Tungsten Electrode (1/8" x 7") represents the modern standard in TIG welding technology. Engineered with a proprietary blend of three rare earth oxides—Lanthanum, Zirconium, and Yttrium—this electrode is designed to outperform traditional thoriated tungsten without the associated radiation hazards. The E3 formula provides a safe, high-performance alternative that meets the rigorous demands of industrial fabrication environments.

One of the primary technical advantages of the E3 tungsten is its thermal efficiency. The electrode runs significantly cooler than 2% Thoriated (Red) tungsten, which directly translates to reduced tip degradation and a longer service life. This thermal stability ensures that the electrode maintains its ground geometry for extended periods, reducing the frequency of re-grinding and downtime. For workshops focused on efficiency and safety, switching to E3 eliminates the need for special handling procedures required for radioactive materials.

The 1/8" (3.2mm) diameter is a heavy-duty size suitable for higher amperage applications. It provides excellent current carrying capacity, allowing for deep penetration on thicker sections of mild steel and stainless steel. Furthermore, the unique oxide blend stabilizes the arc, providing consistent ignition and re-ignition characteristics that are crucial for automated or repetitive welding tasks. Whether used in direct current (DC) or alternating current (AC), the E3 purple tungsten delivers reliable performance across the board.

Key Technical Benefits

• Safety First: Completely non-radioactive composition eliminates health risks associated with grinding thoriated tungsten.
• Thermal Management: Operates at lower temperatures, preventing tip erosion and burn-back.
• Versatility: Capable of handling both AC and DC currents effectively, making it a true "all-in-one" solution.
