摘要： PROBLEM TO BE SOLVED: To provide an arc welding equipment capable of preventing arc cutting and suppressing sputter by controlling the output of an arc control unit to an optimum value during a predetermined period from an instant shifted from a short-circuit state to an arc discharge state.
SOLUTION: The arc welding equipment can control the output of an arc control unit to an optimum value by controlling the resistance between a welding voltage detection unit and a short-circuit control unit to be at least a predetermined value with the time of shift from the arc discharge state to the short-circuit state as a starting point, and controlling the resistance between the welding voltage detection unit and the short-circuit control unit to be substantially zero with the time of shift from the short-circuit state to the arc discharge state as a starting point.
