ULTRASONIC WELDER CONTROLLED BY MICROPROCESSOR

摘要

An ultrasonic welding apparatus e.g. for plastics materials, includes a microprocessor for sequentially controlling the operation and monitoring the status of the welder. The microprocessor controls operations of a plurality of actuators 10 and power supplies. In addition, the status of the apparatus and the power provided from each power supply is monitored and displayed on units 22. Alarm indicators 36, 38 are activated in the event of incorrect welder operation or if the power supplied to a converter is outside a predetermined range of power levels.
