Zirconiated Tig Tungsten White Tip

The Zirconiated tungsten electrode contains circa 0.15% – 0.40% zirconium and a minimum of 99% tungsten. This grade of tungsten conforms to AWS classification EWZr-1. These tungstens are very durable and resistant to splitting due to the extreme stable arc that is produced during use. The high current-carrying capacity is parallel and generally greater than that of the red tip thoriated tungsten.

This tungsten electrode is used in the Tig Welding process and is designed mainly for AC welding (ie. Aluminium). The end of this white tip tungsten retains its balled tip which enhances its resistance to contamination. However, this tungsten is not recommended for DC welding applications including mild steel and stainless steel.

Features & Benefits

• Conforms to AWS classification EWZr-1.
• Have an extreme stable arc which makes them very durable and resistant to splitting.
• Designed specifically for AC welding (mainly aluminium materials).
• White Tip makes them easy to distinguish.

What is a tungsten electrode?

Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal which is just over 3,400 degrees Celsius.
These tungsten electrodes are available in a variety of lengths and sizes and are composed of either pure tungsten or an alloy of tungsten and other rare-earth elements and oxides. Choosing an electrode for GTAW depends on the base material type and thickness and whether you weld with alternating current (AC for Aluminium) or direct current (DC for Mild & Stainless Steels).
It is also important to optimising the results and preventing contamination and rework by choosing the correct end preparation. These options include pointed, balled or truncated. Each electrode is colour-coded at the tip to eliminate confusion over its type.

We also offer a range of Aluminium Tig Wire from stock including grades 4043, 5356 & 5556.
