Abstract
An operation data display device for a robot allowing an operator to recognize operation data on a plurality of operations performed by the robot at a time. When an arc start command is read out from a taught operation program by the robot controller, a welding start command is issued to an arc welding power supply. The arc welding power supply starts supply of a welding current to a welding torch mounted on a robot. Values of the welding current in a welding operation is outputted to a robot controller and sampled at every predetermined period and recorded. When an arc end command is read out from the operation program, the arc welding power supply terminates the welding operation and output of the values of the welding current. The robot controller transfers a file containing the data of the actual welding current to a personal computer. The personal computer displays representations of the received operation data in the form of line graphs of reduced size for the plurality of welding operations: in one frame on a display screen.
