Q796F63 - ESAB Gold WL15 Lanthanated Tungsten Electrodes 2.4mm (10-Pack)

High-Performance Lanthanated Tungsten for Precision Welding

The ESAB WL15 Lanthanated Tungsten Electrodes represent a premium solution for TIG welding professionals requiring versatility and safety. These electrodes are doped with approximately 1.5% Lanthanum Oxide (La2O3), a non-radioactive additive that significantly enhances the electron emission qualities of the tungsten. This specific composition, identified by the industry-standard Gold color code, offers a work function similar to thoriated tungsten but without the radiological hazards associated with Thorium. This makes the WL15 an ideal choice for workshops prioritizing health and safety regulations without compromising on arc performance.

Technically, the 2.4mm (3/32 inch) diameter provides a robust current carrying capacity, suitable for a wide range of amperage settings typical in general fabrication and pipe welding. The electrodes feature a precision ground finish, ensuring optimal electrical conductivity and arc stability immediately out of the box. The 1.5% Lanthanum content facilitates excellent ignition and re-ignition properties, which is particularly beneficial in automated or orbital welding applications where cycle times and consistency are critical. Furthermore, these electrodes exhibit a lower burn-off rate compared to pure tungsten, resulting in longer service life and reduced downtime for electrode preparation.

The WL15 is a true multi-purpose electrode. It performs exceptionally well in DCEN (Direct Current Electrode Negative) applications for welding carbon steels, stainless steels, nickel alloys, and titanium. Additionally, it is increasingly preferred for AC (Alternating Current) welding of aluminum and magnesium alloys, especially when using modern inverter power sources with square wave technology. The electrode maintains a sharp point well, resisting the formation of a ball at the tip better than pure tungsten, which allows for tighter arc control and deeper penetration profiles.

Supplied in a pack of 10, these 175mm length electrodes are compatible with standard collets and collet bodies found in most TIG torches. They offer a reliable, high-quality consumable option for industries ranging from aerospace and automotive to general maintenance and repair.
