    Thorium tungsten electrode is the earliest rare earth tungsten electrode used, and it is also the tungsten electrode variety with the best welding performance so far. The performance of thorium tungsten electrode is better than pure tungsten electrode in many aspects. Thorium oxide provides a current-carrying capacity that is about 20% higher than that of pure tungsten, and generally has a longer service life, which is more helpful to prevent pollution during welding. Using thorium tungsten electrode, arc starting is easier, and the arc is more stable than pure tungsten electrode or zirconium tungsten electrode.

    Thorium tungsten electrodes are widely used for welding stainless steel/carbon steel/copper/iron/nickel and other metals. Especially if the working current is above 200A, in addition to welding aluminum, it is recommended to use red-headed thorium tungsten. The gray head wears quickly under high current, which affects the welding effect.

    Features:

    1. Easy to operate, large current load;

    2. It is easy to start the arc, the arc is stable, and the arc breaking gap is large;

    3. Small loss and long service life;

    4. Higher recrystallization temperature and better conductivity;

    5. It has a wide range of applications and can weld a variety of metals and alloys.
