E3® Tungsten Electrodes
Improved Arc Starts and Longer Electrode Life
For tungsten inert gas welding (TIG), the non-fusing and temperature resistant tungsten electrode, in addition to the torch, the energy source, and the inert gas, are all major factors for obtaining beautiful welds and strong joining results.
E3 Tungsten are electrodes with rare earth mixed oxides. Compared to thoriated electrodes, E3 is less harmful to the environment and not radioactive.
E3 Electrode Features and Benefits:
- Excellent ignition and consistent welding properties
- Universal and suitable for all applications for DC and AC welding pf non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper, and magnesium alloys
- Reliable and usable for automated welding
- Increased current carrying capacity
- Longer service life than thoriated electrodes

E3® Tungsten Electrodes come in packs of 10 and are 7 inches in length. Standard offering is 1/16".
Lanthanated electrodes are best for DC and AC welding applications. Their main areas of application are the welding of non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys. These electrodes are also suitable for use in micro-plasma welding.
Ignition characteristics are enhanced with increased amounts of lanthanum oxide (La2O3). The overall service life and current carrying capacity is lower than the E3® electrodes.

- WLa 15 = Gold
- WLa 20 = Blue
By adding cerium oxide (CeO2), these electrodes have an increased capacity compared to pure tungsten electrodes, however the WCe electrodes have a lower capacity than the E3® and WL electrodes.
Main areas of application are in the DC and AC welding of non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys in the low and middle current range.

Undoped electrodes consist of pure tungsten. The main area of application for this type of electrode is the AC welding of aluminum alloys with excellent arc stability.
WP-electrodes are not suitable for DC welding.
- Color-coding: Green
Tungsten electrodes with the addition of zirconium have a lower risk of contaminating the weld from deposits of tungsten.
The main area of application for this electrode is AC welding. They are limited in their suitability for DC welding.
