HORN AND FIXTURE ALIGNMENT
For maximum productivity, the clearance between the horn and the part
should be at a minimum. However, adequate clearance should be provided to
enable easy loading and unloading of the part from the holding fixture. (The
maximum stroke distance is 3-1/2".) Ensure that the horn does not contact the
part when the head is close to the limit of its down travel distance. Otherwise,
the horn may not have sufficient distance to travel downwards to achieve a full
depth of weld. Set welding height as described below:
1. Position the holding fixture loosely on the base plate using 3/8-16 screws.
2. Place the part to be welded in the fixture.
3. Before loosening the column clamps, hold onto the head assembly firmly
as it can rise upwards rapidly once the clamps are released. While holding
the head assembly, loosen the two column clamps (counterclockwise) and
move the head up or down as required. Then tighten the column clamps.
4. Set the air pressure to zero by turning the PRESSURE regulator knob
(located at the top of air filter/regulator assembly) fully counterclockwise.
5. Loosen the column clamps once again and manually lower the head until
the horn contacts the part. Tighten the clamps.
6. Loosen the cap screws on the converter housing door and gently rotate the
head and horn as required to ensure proper horn-to-part alignment.
Support the head
before releasing the
column clamps so that
it cannot crash down or
fly up. Ignoring this
warning might result in
injury and/or damage to
the equipment and part
being welded.
When the air pressure
is decreased, the
converter housing can
drop down to its limit,
so be sure to either
support it or remove
anything in its path.
