2% Lanthanated (Blue) EWLa-2/WL20 Tungsten

2% Lanthanated tungsten is one of the best general purpose electrodes.  Suitable for both Alternating Current (A/C) or Direct Current (D/C) using inverter or transformer based constant current power sources.  It is good for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys and is typically our recommendation if you are purchasing your first package of tungsten electrodes.
