Abstract
In a conventional arc welding robot control unit, since an emergency stop circuit for a robot and an emergency stop circuit for a welding machine exist independently of each other, not only the circuit configuration thereof is long but also the emergency stop enforcing processings and emergency stop removing processings are executed individually. To solve these problems, according to the invention, there is provided an arc welding robot control unit which comprises an inverter circuitfor enforcing arc welding, main power supply switches-for turning on and off a main power supply used to supply power to the inverter circuita main power supply control partfor controlling the main power supply switches-and an emergency stop buttonfor emergency stopping the operation of a robot, wherein, when the emergency stop buttonis depressed to thereby put the robot into emergency stop, the main power supply switches-can be turned off in linking with the robot emergency stop.
