鑭鎢電極的導電性能最接近2%釷鎢電極，電焊工不需要改變?nèi)魏魏附硬僮鞒绦蚓湍芊奖憧旖莸氖褂茫@種電極替代釷鎢電極而免受釷鎢電極的放射性危害。如果無過載電流，壽命比釷鎢更長，在大多數(shù)使用中起弧更容易。尤其擅長防止熱沖擊，短期焊接中重復點火的情況下，焊接良好避免污染。鑭鎢電極另一優(yōu)點表現(xiàn)在電流高而燒損率最小。

The electric conductivity of Lanthanum-Tungsten Electrode is most closed to that of 2% Thoriated Tungsten Electrode. Welders can easily replace Thoriated Tungsten Electrode with Lanthanum-Tungsten at either AC or DC and do not have to make any welding program changes. If there is no overloaded current, Lanthanum-Tungsten Electrode has longer life than Thoriated Tungsten Electrode. Especial for preventing thermal shock, short cycle and repeated welding, this could help to reduce contamination. Another advantage of Lanthanum-Tungsten Electrode is being able to bear high current and have the lowest burn-loss rate.
