    Description

    Box of gas lens cups #4, 10 units for precise and secure TIG welding

    This box of gas lens cups #4, 10 units is an essential consumable for TIG welders looking to maintain a high level of precision and stability in every job. Designed specifically for WP-9, WP-20, and WP-25 torches, the cups are made from high-purity alumina, a material resistant to extreme heat and thermal shock.

    Optimized gas flow thanks to the gas lens design

    Gas lens cups improve inert gas coverage, allowing for a more uniform and stable flow. This is especially useful in applications where weld quality is critical, such as high-performance component manufacturing or work on sensitive materials. Benefits include:

    • Reduced gas flow turbulence, even with extended electrode usage.
    • Increased arc stability in hard-to-reach areas or complex geometries.
    • Reduced risk of oxide inclusion and contamination in the weld pool.

    Compatibility and ease of use

    These cups are fully compatible with WP-9, WP-20, and WP-25 torches, making them easy to integrate into standard setups with no need for additional adaptors. They are simple to install and should be replaced periodically when worn out to maintain optimal gas flow.

    Recommended applications

    Thanks to their thermal resistance and gas lens design, these ceramic cups are ideal for demanding environments, such as:

    • Manufacturing exhaust systems and high-performance automotive components.
    • Precision welding requiring strict control of protective gas.
    • Work with stainless steels, alloys, and reactive materials.

    Product contents

    • 10 ceramic cups #4 gas lens type.
    • Made from alumina, resistant to heat and thermal shock.
    • Compatible with WP-9, WP-20, and WP-25 torches.

    A practical and reliable solution to keep your workbench stocked with the consumables you need, minimizing downtime and ensuring you're always ready for any task.
