    MCCB Highlights

    Advantages and highlights of welding process equipment for MCCB Electronic type hardware parts

    Side heating resistance welding process: the silver spot welding transfers heat from copper heating to silver spot welding. The silver spot has no electrical corrosion damage, which does not cause the silver spot surface to fade and become soft. It retains the original state of the silver spot. The contact has no damage, and the welding consistency is good, which increases the mechanical life and electrical life of the contact point by 15%.

    Infrared temperature control technology: is used to precisely control the welding parameters, which ensures the welding quality and greatly improves the service life of the product by 50%.

    Frequently Asked Questions

    Q: What is the advantage of side heating resistance welding for MCCB?

    It transfers heat from copper heating to silver spot welding to prevent electrical corrosion, keeping the silver spot's original state without fading or softening.

    Q: How does this welding process affect the lifespan of the contact point?

    By ensuring damage-free contacts and excellent welding consistency, it increases both the mechanical and electrical life of the contact point by 15%.

    Q: What is the role of infrared temperature control in MCCB manufacturing?

    Infrared temperature control technology precisely regulates welding parameters, securing high-quality welding output consistently.

    Q: By how much does the infrared temperature control improve product service life?

    The implementation of precise infrared temperature control parameters improves the overall service life of the product by 50%.

    Q: Does the silver spot get damaged during the welding process?

    No, the side heating resistance welding process ensures that the contact point has no damage and retains its original structural integrity.
