TIG Welding Wear Parts and Consumables
The precision and cleanliness of TIG (tungsten inert gas) welding depend heavily on the quality of the wear parts and consumables used. We understand this, which is why we supply exceptional-quality parts for this process. At the heart of our product range are tungsten electrodes, which maintain a stable arc. We offer a wide selection of tungsten electrode types (e.g. thoriated, lanthanated, ceriated and zirconiated), identified by colour codes. Our experts can help you select the right electrode for the current type (AC/DC) and the material being welded. Other essential consumables we offer include ceramic gas nozzles, which direct a concentrated flow of shielding gas into the welding zone, protecting the molten metal from oxidation. Our range also includes high-quality collets and gas distributors, which ensure accurate electrode positioning and even gas distribution. Regular replacement of these parts, which are readily available from us, is essential for consistently achieving high-quality TIG welds.
