4.10 Adjusting Welder Height and Aligning the Horn

For maximum welding efficiency, position the welder so that the distance between the
workpiece and the horn is at a minimum; however leave enough room to allow for easy
removal of the workpiece from the fixture.
As the maximum travel of the carriage is 4 in/101.6 mm (minimum 1/4 in/6.35 mm), take
care to ensure that the horn contacts the workpiece before the carriage is close to the
limit of its travel. Under such conditions, the carriage may bottom out at maximum trigger
pressure before reaching the full depth of weld.
Set the welder height as follows:
1. Position the fixture loosely on the work surface, On the base, use the M 10 x 1.5 threaded holes.
CAUTION
2. Holding the welder in place, loosen the two column clamps.
WARNING
3. Use the elevation handle to adjust the height of the welder for the desired stroke length. For
proper triggering, provide a minimum stroke length of 1/4 inch. Then tighten the column clamps.
4. Place the workpiece to be welded in the fixture.
5. Set the pressure regulator to zero and manually lower the carriage until the horn contacts the
workpiece.
6. Loosen the carriage door screws and rotate the stack until the horn is properly aligned with the
workpiece. Tighten the carriage door screws.
7. Adjust the air pressure to 15 psi.
8. Use HORN DOWN to check the fixture's position. Press HORN DOWN, then the START SWITCHES.
The horn will descend and remain down under pressure, although ultrasonic energy will remain
off. While holding the horn against the workpiece, tighten the fixture on the base plate. Further
leveling of the fixture may be required, as indicated by test welding results.
9. Press HORN DOWN again to raise the horn back into its normal position.

General Warning
Before inserting screws into the base holes:
1. Check the thread ID on the base.
2. For m (mm) use M10 x 1.5 cap screws.
General Warning
To prevent personal injury or damage to the equipment or workpiece
being welded, always hold the welder in place before releasing the
column clamps. This procedure may require two persons.
