Features:
<< Application: Tungsten electrodes for TIG welding.
<< WT20: 2% thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30% tungsten and 1.70 to 2.20% thorium.
<< WY20: contains 1.8%-2.2% Yttria which its electron function of 2.8eV-3.2eV.
<< WL20: 2.00% lanthanated tungsten electrodes (AWS classification EWLa-2.0)  have excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics—many of the same advantages as ceriated electrodes.
<< WC20: 2% ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30% tungsten and 1.80 to 2.20% cerium.
<< WL15: 1.5% lanthanated tungsten electrodes (AWS classification EWLa-1.5)  have excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics—many of the same advantages as ceriated electrodes.
<< WZ8: The most commonly used in alternating current welding,which contains a small amount of Zirconium oxide. It's electron work is 2.5eV-3.0eV
<< WR20:  It is a non-radiation material. It is good to balance the electron mobility and evaporation rates, making tungsten electrodes to maximize their performances.
<< WES: It contains rare earth element, including 1.5% lanthanum oxide, 0.8% zirconia oxide and 0.8% yttrium oxide.
<< WP: Pure tungsten electrode is the earliest use of electrodes in TIG welding. It contains tungsten content minimum 99.5%, without other impurities.
