BWS3327GE3 - E3 Purple Rare Earth Tungsten Electrodes 3/32" x 7" (10-Pack)

Advanced E3 Rare Earth Tungsten Technology

The E3 Purple Tungsten Electrode (3/32" x 7") represents the modern standard in TIG welding technology. Engineered with a proprietary blend of rare earth oxides—specifically 1.5% Lanthanum, 0.08% Zirconium, and 0.08% Yttrium—this electrode is designed to outperform and outlast traditional thoriated tungsten without the associated radioactive hazards. The unique composition ensures that the oxides are evenly distributed throughout the metal matrix, providing consistent performance from the first arc strike to the last inch of the rod.

For industrial applications involving Stainless Steel and Mild Steel, the E3 electrode offers exceptional arc stability and ignition characteristics. Unlike pure tungsten, the E3 blend lowers the work function of the electrode, allowing for easier starting and a more stable arc at lower amperages. Furthermore, these electrodes run significantly cooler than their thoriated counterparts, which reduces tip degradation and maintains the ground geometry for longer periods. This thermal efficiency translates to less downtime for regrinding and higher productivity in automated or manual welding operations.

While specifically highlighted for steel applications, the E3's versatility extends to AC welding of aluminum and magnesium, making it a true "universal" electrode for diverse fabrication shops. Its ability to handle high current loads without splitting or spitting makes it a superior choice for critical welds where inclusion-free results are mandatory. The 3/32" diameter is the industry workhorse size, perfectly balanced for medium-gauge materials and general fabrication tasks.

Technical Specifications & Safety

Safety is a paramount concern in modern welding environments. The E3 Purple Tungsten is entirely non-radioactive, eliminating the health risks associated with grinding radioactive thoriated dust. This makes it compliant with stringent safety regulations in nuclear, aerospace, and food processing industries. The electrodes are color-coded purple for instant identification and are manufactured to precise tolerances to ensure straightness and consistent diameter.
