Troubleshooting may involve clearing material mis-feeds, replacing worn components such as welding electrodes, identifying and replacing faulty wiring, sensors, actuators, motor drives, power supplies, and control panels, adjusting sensors, clearing robot faults, tweaking robot points, and modifying equipment for improved operation. Processes may include manual assembly operations, resistance welding, laser welding, ultrasonic welding, laser marking, cleaning, adhesive application, in-process inspections, and the operation of automated equipment.
