For iQ Explorer or iQ Explorer II:
a. Select Exit.
b. Press No when asked to set the position.
c. Follow the instructions on the screen.
The following procedure may be helpful in leveling the
fixture in some applications. To perform this procedure,
use a piece of carbon paper and a piece of white paper.
10. Place an un-welded part in the fixture.
11. Place a piece of white paper on top of the sample
part.
12. Place a piece of carbon paper, carbon side down, on
top of the white paper.
13. Press the OFFLINE mode button on the Control
Panel. The screen and power indicator should
change to yellow. Alternatively, select the Utilities
tab in iQ Explorer and check the Off-line box.
14. Cycle the equipment by holding both operate
switches or by triggering the automation switch.
(See the NOTE below.)
15. When one cycle is completed, the pressure developed
between the horn and the sample part will have left
marks from the carbon paper on the white paper.
If the fixture is not level, the carbon markings will
be darker in some areas than in others. All carbon
markings will be uniform when all adjustments have
been made properly.
16. Adjust the leveling of the fixture and repeat this
procedure until you are confident that the fixture is
level.
17. To re-enable ultrasound for welding, press the
ONLINE button on the control panel. Alternatively,
uncheck the Off-line box in the Utilities tab in iQ
Explorer.
On some applications, leveling may be difficult to
achieve as described above. In these instances, sample
parts would need to be welded, measured for parallelism,
and the leveling adjusted correspondingly.

NOTE
Since no melting will occur during this
process, the intended "weld collapse
distance" should be much smaller than
on a typical weld to avoid generating
excessive forces.
