The new Low Power Unit (LPX) platform of ultrasonic welders from Branson Ultrasonics Corp., Danbury, Conn. (bransonultrasonics.com), is designed to meet the needs of users with low-power requirements—up to 550 Watts. The LPX units feature a number of new user interface/process control features designed to make set up, configuration and navigation easier. Included are: an icon-based user interface, digital parameter entry, and the ability to save and recall up to 10 presets. Also, the 1-millisecond data sampling rate is said to provide superior performance.
LPX units feature multiple weld modes, power levels and frequencies. The standard weld modes are continuous, time and energy. They are also available with an optional factory-installed ground detect weld mode. These units come in three frequencies: 20 kHz at 150 and 550 Watts; 30kHz at 550 Watts; and 40 kHz at 15 and 550 Watts.
