Lanthanum Tungsten electrodes (gold end) are universal TIG electrodes that can
be used in direct and alternating current. They are particularly recommended
for welding pure materials or aluminum, titanium, nickel, copper and magnesium
alloys. The higher rate of lanthanum oxide in their composition gives them
slower wear and less current-intensive ignition than for WR2 electrodes. They
are recommended for low currents.
