Set the welder height as follows:
1.
Position the fixture loosely on the work surface. On the base, use the
existing 3/8-16 in threaded holes.
2.
Holding the welder in place, loosen the two column clamps.
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 people.
3.
Use the elevation handle to adjust the height of the welder for the
desired length of carriage travel. For proper triggering, provide a
minimum length of 1/4 in. 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 lbs.
8.
Use HORN DOWN to check the fixture's position. Press HORN DOWN,
then the palm buttons. 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
weld results.
9.
Press HORN DOWN again to raise the horn back into its normal
position.
