Abstract

"MáQUINA DE SOLDAGEM POR PULSOS DE ARCO ELéTRICO COM CONTROLE DE CURTO-CIRCUITO". A presente invenção refere-se a uma máquina de soldagem de arco elétrico com um gerador de forma de onda controlado para criar um processo de soldagem envolvendo fluxo de corrente entre um eletrodo e uma peça a soldar em que o processo de soldagem compreende uma sucessão de formas de onda de pulsos, cada uma tendo uma parte de corrente em rampa ascendente, uma parte de corrente em rampa descendente, e uma parte de corrente de fundo, um circuito sensor de voltagem para detectar um curto-circuito entre o eletrodo e a peça a soldar e um circuito de reinicialização para reinicializar o gerador de forma de onda com a detecção de um curto-circuito. O eletrodo de preferência é um fio compacto que pode ser na forma de um fio pulsador de metal.
