An ultrasonic welder is provided which automatically recognizes and reliably welds varying weld zone sizes of material. The welder comprises a base, a transducer, a tip, an anvil, a gathering tool, and an actuator for moving both the anvil and gathering tool to define a weld zone. An encoder reads movement of the actuator and a microprocessor determines weld zone size to control the transducer for maximizing weld efficiency. Preferably, a horn is mounted between the transducer and tip and the horn is dynamically mounted along an axis of the transducer to transmit the maximum amount of ultrasonic energy to the weld.
