Abstract

MAçARICO DE ARCO DE PLASMA. A presente invenção refere-se a um maçarico de plasma que tem um membro móvel que carrega um eletrodo e móvel ao longo de um furo do membro tubular que tem um bocal em uma extremidade.Um membro de pistão acoplado ao membro móvel move o eletrodo entre posiçõesinoperante e operável dentro do furo, o membro móvel sendo tensionado para fora da uma extremidade do furo. Um primeiro membro de vedação acoplado ao membro de pistão permite um fluxo de fuido para dentro do furo para atuar sobre o membro de pistão para mover o eletrodo para a posição operável quando o bocal / eletrodo está acoplado ao membro tubular. Um segundo membro de vedação, acoplado ao furo, acopla o membro de pistão quando o bocal / eletrodo é removido. O fluxo de fluido entra no furo entre os membros de vedãção, o segundo membro de vedação assim impedindo a operação do maçarico quando o bocal / eletrodo é removido impedindo o fluxo de fluido de atuar sobre o membro de pistão.
