Title: ARC WELDING MONITORING DEVICE
Abstract:
An arc welding monitoring device which can easily recognize the correspondence between the operating path of a robot, namely, the weld line information of a work to be welded and detected data such as welding voltages and currents. The monitoring device is provided with means (4 and 5) which detect at least either welding currents or welding voltages, a means (14) which retains the detected data of the means (4 and 5), a means (14) which stores the operating path of the robot, and a means (12) which displays at least either the welding currents or welding voltages detected by means of the detecting means (4 and 5) and the operating path of the robot stored by means of the storing means (14) on a display, sets an extent on the operating path displayed on the display, and makes arc welding monitoring displays within the set extent.
