Introduction

Add 1.8% -2.2% of lanthanum oxide into tungsten can be called as WL20 lanthanated tungsten electrode. It has the highest content of lanthanum oxide in all lanthanum tungsten electrodes, so its performance will be relatively improved. High content of lanthanum oxide can make the type of electrode quickly ignite the arc, such as welding rod, wire and so on.

Trademark

Because of high content of lanthanum oxide, WL20 lanthanated tungsten electrode is often used in place of thorium tungsten electrode, which has lanthanum oxide content of 1.80 to 2.20%. Content of other impurities is less than 2.0%. Although the content of lanthanum oxide are the highest among three lanthanum tungsten electrodes, but its tungsten content is relatively low. Electrode tip color is sky blue.

Characteristic

Lanthanum tungsten electrode has 2% lanthanum oxide which may be one of the best tungsten electrodes to replace thorium tungsten electrode. Compared to thorium tungsten electrode, lanthanum tungsten electrode has a good arc characteristic, igniting in faster speed with a longer life. It is mainly used in AC and DC power inverter and transformer welding. Conductivity of lanthanum tungsten electrode is most closed, which is a two percent of thoriated tungsten electrode, having excellent welding effect.

Packing

Each tungsten electrode packed in plastic case, 10 to a plastic case, and its length is 150mm or 175mm, 1000 pieces per box.
