2.4 Controls
• Up Speed: Controls the upward speed of the ultrasonic stack. This control is used to raise the
stack quickly for other mechanism actions and for quick part removal
• Down Speed: Controls the downward speed of the ultrasonic stack. This control is used to
prevent damaging the parts to be welded, and increasing/decreasing cycle times to get better
weld results
• Cooling Air: Controls the cooling air flow rate coming out of the cooling hose on the front of the
actuator. Cooling air is used to keep the weld area and the converter within a reasonable
temperature during welding
• Down Stop: The down stop is used to prevent contact between the Horn and Anvil if the welder
is cycled without the part(s) to be welded. A minimum gap of 0.0004 in (0.10mm) is
recommended
• Up Stop: The up stop is used to limit the upward travel of the horn. It is used to limit the upward
travel to reduce cycle times and to ease the loading and unloading of parts
