Abstract

disposição de eletrodo. a presente invenção refere-se a um instrumento aperfeiçoado, onde o eletrodo (20, 20') está provido de um dispositivo de dissipação de calor (28, 28') na forma de um revestimento de uma ou múltiplas camadas (29, 29'), (30). este dispositivo apresenta, em relação ao material do corpo principal do eletrodo (27, 27'), de preferência, uma condutividade elétrica mais alta bem como também uma condutividade térmica mais alta. além disso, de preferência, apresenta uma temperatura de fusão tü mais baixa do que o revestimento, de preferência, 1100°c. se o revestimento (29, 28', 30) é de múltiplas camadas, então a temperatura de fusão to da camada de superfície externa (38), de preferência, também está abaixo (1100°c), em particular, abaixo de (1000°c).
