1, Superior Arc Stability: Features 2% Lanthanated composition for fast arc striking, low burn-off, and consistent arc stability in both AC and DC welding.
2, Non-Radioactive Material: Made from non-radioactive tungsten, providing a safer alternative with excellent electrical conductivity for all welding tasks.
3, Precision Manufacturing: Produced to exact size specifications (1/16" x 7") ensuring reliable performance and resistance to thermal shock without splitting.
4, Versatile Application: Ideal for TIG welding a wide range of materials including aluminum, stainless steel, copper, titanium, and nickel alloys.
5, Standard Compliant Pack: Includes 10 pieces of high-quality electrodes that adhere to the established AWS A5.12M/A5.12:2009 industry standard.
Q: Can I really use Blue Tungsten for both Aluminum and Steel?
Q: Can I really use Blue Tungsten for both Aluminum and Steel?
A: Yes. Blue (2% Lanthanated) is known as the "Universal Electrode."
For Steel (DC): It holds a sharp point longer than Red tungsten and is non-radioactive.
For Aluminum (AC): It handles AC current exceptionally well on modern inverter machines, maintaining a stable arc without wandering.
Q: Is this tungsten radioactive?
Q: Is this tungsten radioactive?
A: No. Unlike Red (Thoriated) tungsten, WL20 Blue Lanthanated is 100% Non-Radioactive. It is safe to handle and safe to grind without worrying about radioactive dust.
Q: Should I "ball" the tip for Aluminum welding?
Q: Should I "ball" the tip for Aluminum welding?
A: Generally, no. Unlike Green (Pure) tungsten, Blue tungsten is designed to keep a sharper geometry.
For Inverter Machines: Grind it to a point, then slightly flatten (truncate) the very tip. It will form a tiny micro-ball during welding, which provides a tight, focused arc perfect for precision aluminum work.
Sizing (1/16" Diameter)
Q: What is the amperage range for 1/16" tungsten?
Q: What is the amperage range for 1/16" tungsten?
A: This size is designed for low-to-medium amperage precision work.
Recommended Range: 10 Amps – 100 Amps.
Warning: If you exceed ~120 Amps, the tip may melt or split. For higher amperages, switch to a 3/32" or 1/8" electrode.
Q: What projects is this size best for?
Q: What projects is this size best for?
A: The 1/16" size is the "finesse" choice. It is ideal for:
Automotive exhaust systems (headers/manifolds).
Thin sheet metal (auto body).
Fine art or jewelry welding.
Any material thinner than 1/8".
Q: Will this fit my torch?
Q: Will this fit my torch?
A: Yes, but you must check your Collet size.
Most TIG torches come set up for 3/32" or 1/8". To use this electrode, you must install a 1/16" Collet and 1/16" Collet Body (or Gas Lens) in your torch, otherwise, the tungsten will slip out.
Performance & Preparation
Q: How does this compare to Red (Thoriated) tungsten?
Q: How does this compare to Red (Thoriated) tungsten?
A: Blue Lanthanated offers very similar performance to Red (excellent arc starts and stability) but with two major advantages: it is non-radioactive, and it performs significantly better on AC (Aluminum) settings.
Q: How should I grind the tip?
Q: How should I grind the tip?
A: Always grind lengthwise (parallel to the rod).
Grinding sideways (circumferentially) creates ridges that cause the arc to wander and spin. Since 1/16" is used for precision, a proper lengthwise grind is critical for a stable arc.
