WL15 1.3 –1.7% LANTHANUM
Request a quote
Non-radioactive. Ideal for use with direct current (DC) as an alternative to 2% thoriated electrodes. Suitable for non-corrosive steels,
titanium alloys, nickel alloys, copper alloys. Better arc starts and stability, low erosion rate, wide range
current. Lanthanum is evenly distributed throughout the electrode and maintains a stable tip shape.

In general, tungsten electrodes are mechanically prepared by grinding with respect to the
their tip shape, the tungsten electrode must be ground parallel to the wheel. The cone height should be from 2 to
up to 2.5 times its diameter. For example, for a 1.6 mm diameter electrode, the cone can range between 3.2 and 4.0 mm.
