Microprocessor controls on two new hand-held ultrasonic welders from Sonics & Materials Inc., Newtown, Conn., allow the devices to be set to weld with digital time and/or energy control. The 20- and 40-kHz, 500W units are designed for spot welding, staking, and inserting. The microprocessor lets users set time from 0.1 to 9.9 sec and energy from 0 to 999,999 J. The controls also feature auto-tuning, frequency display, digital amplitude control, ultrasonic power load meter, and upper/lower weld limit settings. The 20-kHz model comes with a standard 12.5-mm, flat-faced welding tip that attaches to a driver that has a threaded end to accept other tips.
