Q790F47 - ESAB WZ3 Zirconiated Tungsten Electrodes 1.6mm - Pack of 10

High-Performance Zirconiated Tungsten for AC Applications

The ESAB WZ3 Zirconiated Tungsten Electrodes are engineered for professional TIG welding applications requiring precision and stability, particularly when working with non-ferrous metals. This pack contains ten 1.6mm x 175mm electrodes, featuring a ground finish that ensures optimal electrical conductivity and arc initiation. The WZ3 classification denotes a specific formulation of tungsten with a small percentage of zirconium oxide, which significantly enhances the electrode's performance characteristics compared to pure tungsten.

Zirconiated tungsten is the industry standard for AC (Alternating Current) welding. Unlike thoriated or ceriated options which are designed for DC, the WZ3 composition excels at retaining a balled tip, which is essential for a stable AC arc. This balling capability allows for smooth current transfer and reduces the risk of tungsten spitting into the weld pool. Furthermore, these electrodes exhibit a high resistance to contamination, making them a reliable choice for critical radiographic quality welds.

These electrodes are specifically designed for welding aluminum and magnesium alloys. The 1.6mm diameter is versatile for thin to medium-gauge materials, providing excellent control at lower to mid-range amperages. The ground finish removes surface impurities found on unground rods, providing a consistent diameter and smoother surface that improves heat dissipation and arc stability. For industrial fabricators seeking reliability in their AC TIG processes, ESAB's WZ3 tungsten offers a superior balance of arc quality and durability.
