• TAURUS THORIATED TIG TUNGSTEN

The Taurus thoriated tungsten electrodes provide excellent resistance against weld pool contamination while at the same time offer the welder easier arc starting capabilities and a more stable arc. Thoriated tungsten electrodes are the most commonly used tungsten material.

• APPLICATION

Thoriated tungsten electrodes are generally used in DC elec-trode negative or straight polarity applications such as car-bon and stainless steels, nickel alloys and titanium, since they operate well even under amperage overloaded. CLASSIFICATIONS AWS EWTh-2

• TAURUS ZIRCONIATED TIG TUNGSTEN

ZIRCONIATED tungsten electrodes exhibit good performance characteristics in AC welding, especially under high-load current. These electrodes can retain a balled end when weld-ing, which results in less tungsten permeation and good cor-rosion resistance. It balls up well in AC welding and has a more stable arc than pure tungsten. Displays excellent per-formance in high load AC welding. Not replaceable by any other electrodes. Resists contamination well in AC welding.

• APPLICATION

ZIRCONIATED tungsten is most commonly used for AC weld-ing of aluminium and magnesium alloys. Preferred when tungsten contamination of weld is intolerable. CLASSIFICATIONS AWS EWZr-1

• TAURUS LANTHANATED TIG TUNGSTEN

The Taurus lanthanated tungsten electrode has an excellent arc-starting characteristic, a low burn-off rate, good arc sta-bility and excellent re-ignition characteristics and is best applied at medium to high-amperage range. These elec-trodes have characteristics similar to the EWCe-2 product, contain lanthanum oxide (lanthana) and are non-radioactive and therefore safe to use in almost all normal conditions and environments. However, precautions must be taken when grinding or machining electrode tips containing thorium ox-ide. Dust particles from such operations need to be con-tained in order to avoid inhalation.

• APPLICATION

Lanthanated tungsten electrodes perform exceptionally well in both AC and DC current and have a low erosion rate. The electrodes are effective for welding aluminium, magnesium, copper and titanium alloys as well as low allowed steels, stainless steel and non-corroding steels. CLASSIFICATIONS AWS EWLa-1.5 (GOLD) AWS EWLa-2 (BLUE)

• TAURUS RARE EARTH TIG TUNGSTEN

Compound tungsten electrode is also known as three ele-ments of rare earth, is used in a variety of applications, in-cluding welding of non-ferrous metals, stainless steel, and other alloys. Its rapid arcing and high percentage arc striking rate makes it ideal for use in welding applications where pre-cision and efficiency are essential. It is a non-radiation material and is good to balance the electron mobility and evaporation rates, making the tungsten electrodes to maximize its life cycle and their performance. The multi-composite Taurus rare earth tungsten electrode offers several features that make it stand out from other welding electrodes. It is designed to complement the proper-ties of tungsten base and rare earth oxides, resulting in ex-cellent welding performance. It has been subjected to strict production processes and formula screening to ensure its high performance.
