Abstract
An apparatus and method controls an arc welding robot. During robot teaching, an allowable width for a command value (central value) is entered via an input. The robot is taught, and operated according to data stored in a memory, and a CPU judges if an actual welding value taken from an external interface during actual welding is within the allowable width corresponding to the entered welding condition command value, and when the actual welding value is outside of the allowable width, operation information of the robot can be immediately displayed by an information noticing device, or stored in the memory, and displayed in batch at the end of one welding stroke. An arc welding condition is monitored only during regular welding, and can be ignored during crater treatment, or a section of unstable welding right after the start of welding can be excluded from the welding condition monitoring object section. As required, depending on characteristics of a wire feeder, the conditions of crater treatment can be changed.
