10Pcs 2% Thoriated WT20 TIG Tungsten Electrode Assorted Size 1/16" & 3/32"
Thorium tungsten electrode containing thorium oxide (Th02 or thorium oxide)
Performance in many ways superior to pure tungsten electrodes. It has the lowest work function
Thoria provide more than pure tungsten higher current carrying capacity of about 20 percent,
Longer life, but also help prevent contamination of the welding time.
Use thorium tungsten electrode arc starting easier and more stable arc than pure tungsten electrodes or zirconium tungsten electrode.
