Lanthanated wolfram electrode features excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics any of the same advantages as ceriated electrodes.
As 1.5% lanthanated wolfram electrode and 2% thoriated tungsten possess close resemblance, 2% thoriated, in some cases, can be replaced without having to make significant welding program changes.

WL15 Tungsten Electrode for TIG Welding/1.5% Lanthanum tungsten

1.5% lanthanum tungsten electrode (Wolfram electrodes), which is also known as WL electrode, contains a minimum of 97.80% tungsten and 1.30 to 1.70% lanthanum
To optimize your welding capabilities, you can consider it as a best choice.
lanthanum wolfram electrode (Wolfram electrodes) works well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources.
The lanthanum is dispersed evenly throughout the entire length of the lanthanated tungsten electrode in the process of production.
This lanthanum wolfram electrode (WL electrode) also maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or the AC from square wave power sources.
Compared to pure tungsten, the addition of 1.5% lanthanated increases the maximum carrying capacity by approximately 50% for a given size electrode.
We can manufacture lanthanum wolfram electrode (Wolfram electrodes) with different content of lanthanum.

Unlike thoriated tungsten, these lanthanated wolfram electrodes are suitable for AC welding and, like ceriated electrodes, allow for the arc to be started and maintained at lower voltages.
