OVERVIEW

High-Performance Zirconiated Tungsten for Industrial AC Welding

The 1/8" Zirconiated Tungsten Electrodes (White) are engineered to meet the rigorous demands of industrial AC TIG welding. Composed of tungsten with a small percentage of zirconium oxide (ZrO2), these electrodes are specifically designed to excel in applications involving aluminum and magnesium alloys. Unlike pure tungsten, Zirconiated electrodes offer a higher resistance to contamination and minimize the risk of tungsten spitting, ensuring a cleaner weld pool and superior radiographic quality.

One of the primary technical advantages of this electrode is its ability to retain a balled end during operation, which is critical for maintaining a stable arc in Alternating Current (AC) processes. The 1/8-inch diameter allows for significant current carrying capacity, making it suitable for medium-to-heavy gauge materials. While it shares some characteristics with pure tungsten, the addition of zirconium significantly improves arc start performance and load handling.

These electrodes are manufactured to strict tolerances to ensure consistency in diameter, straightness, and composition. They are an essential consumable for fabrication shops, aerospace manufacturing, and automotive repair facilities where precision aluminum welding is required. Please note that Zirconiated tungsten is not recommended for DC welding applications.

FAQ

Zirconiated tungsten is primarily used for AC TIG welding of aluminum and magnesium alloys due to its excellent balling properties and arc stability.

No, Zirconiated tungsten is not recommended for DC welding on steel. You should use Thoriated (Red) or Lanthanated (Blue/Gold) for steel applications.

This electrode is color-coded White.

Zirconiated tungsten typically has very low to negligible radioactivity compared to Thoriated tungsten, making it a safer alternative for many AC applications.

This is a 1/8 inch diameter electrode, which is approximately 3.2mm.

For Zirconiated tungsten on AC, you typically want to form a balled end. This can be achieved by briefly striking an arc on a piece of copper or using your machine's AC balance settings.

Yes, for most applications. It handles higher amperages, starts easier, and resists contamination (spitting) much better than Pure Tungsten.

These are standard 7-inch (175mm) length electrodes.
