Description: Lanthanum Tungsten Electrodes

Lanthanated tungsten electrode contains 0.8%-2.2% lantana, the electron work is 2.8eV-3.0eV. It is easy to arc and arc stability with low current, it is mainly used in DC, performance well in AC welding. Lanthana has better of Creep Resistance, strong ductility, smaller stirring rate,therefore the tip temperature of lanthanated lower,which helps to precent grain growth, the service life of electrode can be increased substantially, without overload current, the life of lanthanated tungsten electrode longer than thoriated tungsten electrode, particularly good at preventing thermal shock, In the welding of short cycle, under the condition ofrepeated ignition, it can be welded well and prevents from pollution. When welding the pipeline, welders are quite satisfied with this lanthanated tungsten, because the service time is long to reduce the downtime.

Diameter: 1.6mm, 2.0mm, 2.4mm, 3.0mm, 3.2mm, 4.0mm.

Packing: Plastic boxes.
