DescriptionPure Tungsten Tig Electrodes 1.0mm x 1 (green)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 identification These TIG electrodes are unalloyed, ‘pure’ tungsten with a 99.5% tungsten minimum and are relatively low cost. They provide good arc stability when using AC current, with either balanced wave or unbalanced wave and continuous high-frequency stabilization. Pure tungsten electrodes are preferred for AC sine wave welding of aluminium and magnesium because they provide good arc stability with both argon and helium shielding gas. The pure tungsten electrode easily forms a balled end but has a tendency to spit at higher currents and this should be considered when making critical welds.
