Thoriated Tungsten Electrode

About Thoriated Tungsten Electrode

• Superior Arc Performance: Offers reliable and easy arc starting with exceptional stability during welding, which helps eliminate arc wandering.
• High Current Capacity: Has a greater current carrying capacity and performs effectively at high temperatures (up to 3,400C) compared to pure tungsten, allowing for a broader amperage range.
• Durability and Longevity: Features a low burn-off rate and maintains a sharpened point for longer periods, leading to extended electrode lifespan and less downtime for re-grinding.
• Reduced Contamination: Deposits less tungsten into the weld puddle, resulting in contamination-resistant welds.
• Composition: Typically composed of 97.3% tungsten and 1.7% to 2.2% thorium oxide, which enhances its electron emission qualities.
• Primary Application: Best suited for DC electrode negative (DCEN) or straight polarity welding on a variety of metals, including:
  • Carbon and stainless steel
  • Nickel alloys
  • Titanium
  • Copper alloys 

• Always use local exhaust ventilation near the source of grinding to capture dust.
• Follow all manufacturer's warnings, instructions, and Material Safety Data Sheets (MSDS) for safe use
