Abstract

"MáQUINA DE SOLDAR DE DOIS ESTáGIOS E MéTODO DE OPERAR A MESMA". A presente invenção refere-se a uma máquina de soldar a arco elétrico do tipo GMAW (A), cuja máquina de soldar (A) inclui uma fonte de alimentação de energia de comutação de alta velocidade (10) com um controlador (130) para criar um primeiro ou segundo processo de soldagem através do intervalo entre uma peça de trabalho (W) e um arame de soldar (E) avançado no sentido da peça de trabalho (W). O primeiro processo utiliza uma primeira forma de onda de corrente e o segundo processo utiliza uma segunda forma de onda de corrente. Um circuito é previsto para comutar entre os primeiro e segundo processos de soldagem. O circuito de comutação inclui um contador (212) para contar as formas de onda nos primeiro e segundo processos e um circuito (190) do processo sendo processado para o outro processo de soldagem quando a contagem de forma de onda do processo de soldagem sendo processado atinge um número pré-selecionado para o dito processo de soldagem."TWO STAGE WELDING MACHINE AND METHOD OF OPERATING THE SAME". The present invention relates to a GMAW (A) type arc welding machine whose welding machine (A) includes a high-speed switching power supply (10) with a controller (130) for create a first or second welding process through the gap between a workpiece (W) and an advanced welding wire (E) towards the workpiece (W). The first process uses a first current waveform and the second process uses a second current waveform. A circuit is provided for switching between the first and second welding processes. The switching circuit includes a counter (212) for counting the waveforms in the first and second processes and a process circuit (190) being processed for the other welding process when the waveform count of the welding process being processed. reaches a preselected number for said welding process.
