2% lanthanated tungsten electrode

2% lanthanated tungsten electrodes (AWS classification EWLa-2) contain a minimum of 97.80% tungsten and 1.80 to 2.20% lanthanum, or lanthana. These electrodes have excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics—many of the same advantages as ceriated electrodes. 2% lanthanated electrodes also closely resemble the conductivity characteristics of 2% thoriated tungsten, meaning, in some cases, it can replace 2% thoriated
