Considered environmentally friendly because thorium oxide has been replaced here with lanthanum oxide, which is non-radioactive. They exhibit
excellent arc ignition capability, low consumption rate, and outstanding re-strike characteristics. Compared to
other types exhibit less tip wear at the same current settings. These electrodes
generally, they have a longer service life and a lower likelihood of tungsten inclusions. They are commonly used in
carbon steels, stainless steels, copper alloys, nickel alloys, and titanium.
