An arc welding robot system includes: a robot on which a welding torch is mounted; a robot control device; and a welding power supply that supplies power to the welding torch. The robot control device includes: a welding command unit that outputs a command to the welding power supply; a measuring unit that measures, a plurality of times for each welding location, an amount of time from when the welding command unit sends a welding start-up command to the welding power supply in accordance with a welding start command of an arc welding program until a notification signal indicating generation of an arc is returned from the welding power supply; a storage unit that stores a plurality of measured measurement values for each welding location; and a preceding time determination unit that determines, for each welding location, a preceding time for outputting the welding start-up command in advance of a timing at which the welding torch arrives at a welding start point corresponding to the welding start-up command, the determination being made on the basis of the values of the plurality of times of measurements for each welding location stored in the storage unit.
