OVERVIEW

High-Performance LaYZr Tungsten for Precision TIG Welding

Elevate your welding quality with these premium LaYZr (E3 style) Tungsten Electrodes. Sized at 1/8-inch (3.2mm) diameter and 7 inches in length, these electrodes are identified by a distinct Lime Green tip. They are manufactured using a sophisticated blend of non-radioactive rare earth oxides—Lanthanum, Yttrium, and Zirconium. This "tri-mix" composition is engineered to provide the best characteristics of traditional thoriated tungsten without the radiation hazards, making them a safe and superior choice for modern welding environments.

The LaYZr formulation ensures reliable arc ignition and excellent stability, even at low amperages. These electrodes are designed to run cooler than their counterparts, which significantly reduces tip degradation and extends the time between regrinds. Whether you are working on critical aerospace components or general fabrication, the consistent performance of these electrodes helps maintain weld integrity and reduces downtime.

Versatility Across Materials

One of the standout features of this tungsten is its incredible versatility. It is optimized for use with both AC and DC currents, allowing you to weld a wide range of materials including:

  • Stainless Steel: Achieve clean, colorful welds with precise heat control.
  • Mild Steel: Deep penetration and stable arc for structural integrity.
  • Aluminum: Excellent AC performance with good balling characteristics when required.

Packaged in a durable case of 10, these electrodes are an essential addition to any professional welder's toolkit, offering a single solution for multiple welding processes.

FAQ

LaYZr (E3) is a non-radioactive blend of three oxides (Lanthanum, Yttrium, Zirconium) that runs cooler and lasts longer than Thoriated (Red) tungsten, which contains radioactive Thorium.

Yes, LaYZr tungsten is excellent for AC welding of aluminum. It maintains a stable arc and can form a suitable tip for AC processes.

Unlike Pure tungsten (Green), LaYZr does not require a large ball. For AC, you can grind it to a point with a small flat land, or let it form a very small ball naturally.

Color codes can vary by manufacturer. While Purple is the ISO standard for E3, some brands use Lime Green or Chartreuse to denote specific LaYZr or non-radioactive blends. Always check the package details.

A 1/8" (3.2mm) tungsten electrode is typically rated for approximately 150 to 250+ amps, depending on the current type (AC vs DC) and gas cup size.

Always grind tungsten longitudinally (lengthwise with the rod) to ensure a stable arc. For DC, grind to a sharp point; for AC, a truncated point is often best.

Yes, LaYZr tungsten is perfectly suited for modern inverter power sources as well as older transformer machines.
