Claims (1)
- 消耗電極と母材間に接続され溶接出力電圧を検出する電圧検出器と、溶接出力回路に直列に接続され溶接出力電流を検出する電流検出器と、前記電圧検出器の検出値にてアーク中か短絡中かを判定するアーク/短絡判定器と、溶接出力極性比率を調整する正極性/逆極性調整器と、前記アーク/短絡検出器の出力信号と電流検出器の出力信号の論理積を行う論理回路と、前記正極性/逆極性調整器の出力信号と論理回路の出力信号により正極性/逆極性出力を制御する正極性/逆極性制御器とを設け、前記正極性/逆極性制御器は短絡やアーク切れであるアーク不安定要因発生時に必ずアーク安定極性となる逆極性出力に制御する消耗電極式交流アーク溶接機であって、
前記論理回路は、前記電流検出器からアーク切れを示す信号と前記アーク/短絡判定器から短絡を示す信号との少なくとも1つが入力されていれば極性を逆極性に出力する信号を出力し、前記正極性/逆極性制御器は、前記論理回路から極性を逆極性に出力する信号を入力している場合には、前記正極性/逆極性調整器の出力信号に関係なく極性を逆極性出力に制御する消耗電極式交流アーク溶接機。
