Abstract

MAçARICO A ARCO DE PLASMA TENDO UM ELETRODO COM PASSAGENS INTERNAS. Um eletrodo para um maçarico de corte a arco de plasma que minimiza a deposição de material de alta emissividade no bico; reduz o desgaste do eletrodo, e aperfeiçoa a qualidade do corte. O eletrodo tem um corpo que tem uma primeira extremidade, uma segunda extremidade e uma relação espaçada relativa à primeira extremidade, e uma superfície externa se estendendo a partir da primeira extremidade até a segunda extremidade. O corpo tem uma face de extremidade disposta na segunda extremidade. O eletrodo inclui também pelo menos uma passagem se estendendo a partir de uma primeira abertura no corpo até uma segunda abertura na face de extremidade. Um controlador pode controlar o fluxo de gás de eletrodo através das passagens como uma função de um parâmetro de maçarico a arco de plasma. São revelados métodos para operar o maçarico de corte a arco de plasma com o eletrodo.
