2% LANTHANTED (BLUE) EWLa-2/WL20
Principal Oxide: 1.8 – 2.2% Lanthanum Oxide
Non-Radioactive. Best general purpose electrode for both alternating current (a/c) or direct current (d/c) using inverter or transformer based constant current power sources. Good for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys. Good arc starts and stability, medium to high amperage range, low erosion rate.
