第１項に記載のアーク溶接機。[Scope of Claim for Utility Model Registration] 1. A welding power source whose output polarity can be switched, and a series of steps for starting welding in response to a welding start command, executing a predetermined crater treatment in response to a welding stop command, and terminating welding. In an arc welding machine equipped with a sequence control circuit for controlling the above, and a polarity switching circuit for switching the output polarity of the welding power source, while at least one of the welding start command and the welding stop command is supplied, Regardless of the setting of the polarity switching circuit, the output of the welding power source is set to the opposite polarity, and during the remaining period during welding, welding is started and stopped to determine the output polarity of the welding power source according to the setting of the polarity switching circuit. An arc welding machine equipped with an interlocking switching circuit that links commands and polarity switching. 2. The arc welding machine according to claim 1, wherein the interlock switching circuit is a circuit that reverses the polarity of the output of the welding power source after a predetermined time delay after the welding stop command is supplied.
