A dual ultrasonic welder unit may be coupled to and carried by a mounting bracket including a base member extending in a an end of a robot arm and may include a first welder including a welding horn adjustable in a Z-axis direction by a first motor mounted within a mounting bar assembly of the first welder. The mounting bar assembly may be coupled to the base member and include a support for adjusting the location of the first welder in an X-axis direction by a second motor mounted to an extension member coupled to the base member and including a threaded member coupled to a follower member coupled to the mounting bar assembly. The dual ultrasonic welder may include a second ultrasonic welder fixedly coupled to the base member. Methods of controlling and operating the dual ultrasonic welding unit include steps of operating the robot and the first and second motors to position the first welder relative to the second welder unit for simultaneously performing ultrasonic welds on at multiple locations on a workpiece.
