6. Tighten the converter housing door screws, and then tighten the fixture on
the base plate.
7. Check for proper mating of fixture, parts, and horn. If the horn and parts
are not in parallel contact, shim the fixture or adjust leveling screws as
required. Adjust the positive stop knob for proper weld depth (see below).
8. Set the UP PRESSURE regulator to a reading of 20 psig (140 kPa/1.4 bar)
on the pressure gauge. (Turn the PRESSURE knob clockwise.) This 20
psig reading is the initial pressure and may later change according to
application requirements.
The UP PRESSURE, used to raise the horn, should be regulated
according to the size of the horn you are using. The larger the horn, the
more UP PRESSURE required.
POSITIVE STOP ADJUSTMENT
The positive stop is set to limit the downward travel of the horn to
approximately 75%. Readjustments may be required. Coarse adjustment of
the clearance between the face of the horn and part should be made using
the elevation control. Fine adjustment should be made using the positive stop.
The positive stop can adjust vertical positioning with a 4" stroke (or optional
6" stroke).
The positive stop adjustment knob is located behind the converter housing.
Turning the knob clockwise will decrease downward travel distance. Turning
the knob counterclockwise will increase the downward travel distance. When
making any adjustments be aware of the necessary clearances required.
NOTE: For maximum
safety and productivity,
adjust the clearance
between the horn and
the part to a minimum
that will still allow ease
of loading and
unloading.
