Supplier's note

  1. Technical Breakthroughs:

    • Thoriated Red Tips: Triple the lifespan of pure tungsten electrodes, reducing downtime.
    • ISO/ANSI Compliance: Ensures compatibility with global welding standards.
    • Diameter Versatility: Three sizes cover 90% of TIG welding scenarios.

  2. Optimal Version Selection:

    • Base Model (2.0mm): Ideal for hobbyists or small workshops handling thin materials.
    • Advanced Model (3.2mm): Best for mid-scale fabrication shops needing balanced performance.
    • Pro Model (4.0mm): Suited for industrial users welding thick materials like pipelines or heavy machinery.

With the Pro Model’s 4.0mm diameter, you can weld 30% thicker materials than the Base Model, ensuring seamless joins in high-stress environments. Pair its 2% thorium content with argon shielding for unmatched arc stability.
