Arc welding device and arc welding system

摘要

An arc welding device according to an embodiment carries out welding while repeatedly generating a short circuit state and an arc state between a consumable electrode and a welding member. The arc welding device includes a detection unit and an adjustment unit. The detection unit detects at least one of a length of a short circuit generation period of this time and a length of an arc generation period of this time. The adjustment unit adjusts an increase rate of a short circuit current in a short circuit generation period of next time according to at least one of the length of the short circuit generation period and the length of the arc generation period detected by the detection unit.
