2% Lanthanated (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 errosion rate.

2% Lanthanated Tungsten is a substitute for 2% Thoriated. It has similar characteristics to 1.5% Lanthanated with better arc starting, arc stability, and less tip erosion. It is composed of 97.3% Tungsten, 1.8%-2.2% lanthanum, and .5% other. Materials Welded- Carbon Steel, Stainless Steel, Nickel Alloy, Titanium, and Aluminum. Package of 10
