Description2.0% Ceriated Tig Electrodes 3.2mm x 5 (grey)Tungsten is a rare metallic element used in manufacturing Tig welding electrodes. The Tig process relies on the tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410ºC. Tungsten electrodes are non-consumable and come in a variety of sizes, they are made from pure tungsten or an alloy of tungsten and other rare earth elements. Choosing the correct tungsten depends on the material being welded, amps required and whether you are using AC or DC welding current. Tungsten electrodes are colour-coded at the end for easy identificationThese TIG electrodes are alloyed with about 2% ceria, a non-radioactive material and the most abundant of the rare earth elements. The addition of this small percentage of cerium oxide increases the electron emission qualities of the electrode which gives them a better starting characteristic and a higher current carrying capacity with no spitting. These are all-purpose electrodes that will operate successfully with AC or DC electrode negative. Compared with pure tungsten, the ceriated tungsten electrodes provide for greater arc stability. They have excellent arc starting properties at low current. If used on higher current applications the cerium oxide may be concentrated to the excessively hot tip of the electrode. This condition and oxide change will remove the benefits of the cerium. The non radioactive cerium oxide has slightly different electrical properties as compared to the thoriated tungsten electrodes. The cerium electrodes work well with the Advanced Squarewave power sources and should be ground to a modified point. 2.0% Ceriated Tig Electrodes 3.2mm x 5 (grey)https://www.wecs-ltd.co.uk/product-category/mig-wires/https://specialisedwelding.co.uk/
