Premium Quality and Size: Manufactured to precise 3/32" diameter by 7" length, conforming to the AWS A5.12M/A5.12:2009 standard for dependable performance.
Optimized DC Performance: The red thoriated (WT20/EWTh-2) electrode provides fast arc striking and a stable, continuous arc for reliable welding in DC applications.
Low Burn-Off Rate: Engineered for resistance to thermal shock, ensuring a low consumption rate and high integrity without splitting, even under heavy amperage.
Versatile Metal Use: Ideal for use on stainless steels, copper alloys, nickel alloys, and titanium alloys, suitable for beginner through professional TIG welders.
Durable, Sealed Storage: Includes 10 electrodes in a high-strength, airtight tube to prevent oxidation, maintain consistency, and ensure long-term preservation and portability.
Q: Is 3/32" the right size for general fabrication?
Q: Is 3/32" the right size for general fabrication?
A: Yes. 3/32" (2.4mm) is the most versatile "do-it-all" size for TIG welding.
Amperage Range: Perfect for 60 Amps to 160 Amps.
Capabilities: It can handle delicate 1/16" tubing but also weld 1/4" plate comfortably. If you only buy one size of tungsten for Steel/Stainless, this is the one to get.
Q: Why choose Red (Thoriated) over Blue or Grey?
Q: Why choose Red (Thoriated) over Blue or Grey?
A: Red Tungsten provides the most stable and focused arc for DC welding.
Benefit: It resists heat better than Ceriated (Grey) and holds a sharp point longer than Lanthanated (Blue) under heavy use. This makes it the favorite for pipe welders and structural fabricators who value consistency.
Q: Can I use this for Aluminum (AC) welding?
Q: Can I use this for Aluminum (AC) welding?
A: No. We do not recommend Red Thoriated for AC welding.
Why: On AC, Red tungsten tends to spit, wander, and form weird nodules on the tip.
Alternative: For Aluminum, please use our Blue (Lanthanated) or Purple (Rare Earth) tungsten.
Q: Is this tungsten radioactive?
Q: Is this tungsten radioactive?
A: Yes. It contains 2% Thorium oxide.
Usage: It is the industry standard and safe to use when welding.
Grinding Safety: The risk comes from inhaling the dust during grinding. We recommend wearing a respirator mask and using a vacuum system or wet-grinder to capture the dust. Wash your hands after grinding.
Q: How should I store these?
Q: How should I store these?
A: Tungsten can oxidize if left in humid environments. Our electrodes come in a High-Strength, Vacuum-Sealed Tube to ensure they stay fresh, straight, and dry until you are ready to use them.
Q: Will this fit my TIG Torch?
Q: Will this fit my TIG Torch?
A: Yes, 3/32" is the standard setup for almost all TIG torches (WP-17, WP-18, WP-26, WP-9, WP-20).
Check: Ensure your torch has a 3/32" Collet and 3/32" Collet Body installed.
Q: What is the best way to grind the tip?
Q: What is the best way to grind the tip?
A: For the best DC arc stability:
Grind Lengthwise: Always grind parallel to the rod. Sideways grinding marks will cause the arc to spin.
Taper Length: For 3/32" tungsten, a taper about 2.5 times the diameter (approx. 1/4" long point) offers the best balance of arc control and heat durability.
