tungsten electrodes:
This is a high-quality range of tungsten electrodes available in thoriated, ceriated, pure and lanthanated (Gold Plus) versions. ESAB tungsten electrodes have excellent welding and ignition properties.
They are delivered in plastic boxes, each containing ten electrodes. The standard electrodes are 175 mm long, the Eco range is 150 mm long.
Pure tungsten electrodes the one without any addition of oxide. This allows the tip to form a clean, balled end which provides good arc stability on AC. The power of electronic transgression is as high as 4.5ev. Requiring a high voltage for arc derivation, it has a low current capacity and is easily burnt. It’s good for application under the condition of AC and in the situation of low welding requirements.
