?NO RADIOACTIVITY?: Ceriated tungsten electrode is a non-radioactive material, long service life.
?APPLICATION?: Cerium tungsten electrode is known to be especially good for DC welding with low amperage,mainly for welding of iron.
?PERFORMANCE?: It starts very easily at low amps and usually requires about 10% less amps to operate than thorated material.
?FEATURES?: Low electronic function, good conductivity, good electron emission ability, good mechanical cutting performance, high elastic modulus, low vapour pressure, high recrystallization temperature.
