To provide an arc welding robot system that displays a current waveform graphically during arc welding and realizes parameter adjustment on a display screen. An arc welding robot system comprises a robot controller and a teaching operation terminal. The robot controller comprises: an arc sensor; and a welding current storage unit that stores the current value of a welding current detected by the arc sensor during implementation of the arc welding. The teaching operation terminal comprises: a control unit; and a display on which data is displayed. The control unit comprises: a welding current display unit that displays the current value and the waveform of the welding current in any weaving cycle on the display; a sampling current area display unit that displays a sampling current area on the display; and a current waveform display shift unit that shifts the waveform of the welding current in a temporal axis direction on the display unit.
An arc welding robot system that performs automatic arc welding by detecting a welding current flowing while welding proceeds with weaving of a welding torch and making the welding torch trace a weld line in a welding work as a center of the weaving using an arc sensor,
