、溶接電圧が所定値以下になつたことで電極、母
材間の短絡状態を検出する比較回路と、この比較
回路により短絡状態が所定時間以上持続して検出
されたとき出力を生ずるタイマ回路と、このタイ
マ回路の出力を受けて短絡状態が所定時間持続し
て検出された時点より溶接電源出力を停止もしく
は低減するとともに、消耗性電極の送給を停止し

アークを再起動させるように溶接電源および電極
送給モータに指令するシーケンス回路とを備えた
ことを特徴とする自動アーク溶接機。 In automatic arc welding machines that use consumable electrodes, there is a comparison circuit that detects a short circuit between the electrode and the base material when the welding voltage drops below a predetermined value, and a comparison circuit that detects a short circuit between the electrode and the base material if the short circuit continues for a predetermined time or longer. A timer circuit that generates an output when detected, and a timer circuit that receives the output of this timer circuit and stops or reduces the output of the welding power source and stops feeding the consumable electrode when a short circuit condition continues for a predetermined period of time and is detected. and a sequence circuit that instructs a welding power source and an electrode feed motor to feed the electrode back and restart the arc after the short circuit is released.
