HDB tungsten 2% thorium 7 " Good price WT20 tungsten electrode
product description
Thorium tungsten electrode is the first rare-earth tungsten electrode used, and it is also the tungsten electrode variety with the best welding performance so far, therefore, the market share of this variety of tungsten electrode is the highest worldwide.
In general, the 2% thoriated tungsten electrode is a relatively good tungsten electrode with the lowest fugitive work and performs well even at overload voltages. The performance of thoriated tungsten electrodes is superior to that of pure tungsten electrodes in many ways. Thorium oxide provides about twenty percent higher current carrying capacity than pure tungsten, generally lasts longer, and helps stop contamination during soldering.
Features:
1. High melting point, arc stability, no self - consumption.
2. Add 0.03 ~ 4% Th02, Zr02, La02 and Ce02 in tungsten to reduce the burning loss of tungsten electrode, increase its service life and avoid polluting welding seam.
3. increase the electron emission ability of tungsten electrode, make it arc starting current, stable arc current is small, arc starting gap and arc breaking gap are big, so the quality of welding seam is high.
