Product Description

Thorium-tungsten electrode is the electrode of tungsten added with **4% of ***** power of its electronic transgression is 2.7ev, *0% less than that of pure tungsten electrode. With a low arc derivation voltage, it’seasy tuo cause arc of high stability. Its current capacity is elevated *0% while its rate of burn spoilage drops low, making it more durable. Thorium-tungsten electrode is fairly widely applied in direct current welding
