    Pure tungsten electrode is the earliest electrode used in TIG welding. It has the characteristics of low resistance, good conductivity and low thermal expansion, and is widely used in various specific welding industries. The pure tungsten electrode contains 99.5% lower tungsten and has no alloying elements. The pure tungsten electrode is only used as a welding electrode under AC conditions or as a resistance welding electrode. It can provide a clean base material surface, and the solder ball becomes sharp when heated. This shape provides a balanced waveform AC welding arc stability, which is particularly good. Pure tungsten has a very high electron escape function, low vapor pressure, low electrical resistance, good electrical conductivity, low thermal expansion, and high elasticity. Therefore, the arc is stable at low current, and aluminum, magnesium and their alloys can be welded well below 5A. However, the emission of electrons requires a higher voltage, and the welding machine requires a high no-load voltage. The tungsten electrode burns out when working with large currents for a long time. Obviously, the end will melt and fall into the molten pool will cause the seam to clamp tungsten, so it is only used for welding some ferrous metals, or welding unimportant parts.

     

    Our tungsten electrode adopts the domestic advanced centerless grinder technology, and the surface of the product has a high degree of smoothness and no burrs. Compared with other products, the arc is more concentrated and more stable.

    Features:

    1. The pure tungsten electrode contains at least 99.5% tungsten, which has excellent conductivity and durability.

    2. Non-radioactive tungsten electrode, no pollution.

    3. Low burnout rate and good arc stability.

    4. Provide 9 specifications of pure tungsten electrodes to meet your different needs.

    5. Mainly used for AC welding of nickel alloy, magnesium aluminum and its alloys.

    Application:

    Pure tungsten electrode does not add any rare earth oxides and has the smallest electron emission ability, so it is only suitable for welding under AC heavy load conditions, such as welding of aluminum and aluminum-magnesium alloys.
