64014000 - 5/32" E3 Purple Rare Earth Tungsten Electrodes (10-Pack)

Premium E3 Purple Tungsten Electrodes for Industrial TIG Welding

Optimize your TIG welding operations with the E3 Purple Tungsten Electrodes, sized at 5/32" (4.0mm) x 7". Engineered for the modern fabrication environment, E3 electrodes represent the pinnacle of non-radioactive tungsten technology. By utilizing a proprietary blend of rare earth oxides (typically including Lanthanum, Zirconium, and Yttrium), these electrodes offer a safe and high-performance alternative to traditional Thoriated (Red) tungsten. They are specifically designed to remain stable at high temperatures, making them an excellent choice for heavy-duty industrial applications where consistency and safety are paramount.

The 5/32" diameter is particularly suited for high-amperage welding on thick materials, providing the current-carrying capacity needed for structural steel, heavy aluminum plate, and pressure vessel fabrication. Unlike pure tungsten, E3 maintains its geometry well, resisting tip degradation even under thermal stress. This results in fewer interruptions for regrinding and higher overall productivity. The electrode's ability to perform exceptionally well on both AC and DC currents makes it a versatile inventory solution, reducing the need to stock multiple types of tungsten for different base metals.

Technical Advantages

• Non-Radioactive Composition: Eliminates the health risks and disposal regulations associated with Thoriated tungsten, ensuring a safer workplace.
• Cooler Running: The oxide blend lowers the work function of the electrode, allowing it to run cooler than thoriated counterparts, which extends the service life of the tip.
• Universal Compatibility: Excellent performance on mild steel, stainless steel, aluminum, titanium, copper, and magnesium alloys.
• Reliable Ignition: Provides dependable arc starts and restarts, crucial for automated systems and critical manual welds.

For industrial facilities looking to standardize their TIG consumables, the E3 Purple Tungsten offers a robust solution that does not compromise on performance. Whether you are welding critical pipe joints or heavy structural components, these electrodes deliver the arc stability and longevity required for code-quality work.
