Physical Description
Mechanical Stop
The mechanical stop limits the downward travel of the horn. To prevent equipment damage,
adjust the stop so that the horn will not contact the fixture when no workpiece is in place. There
is an indicator on the right side showing the position of the stop block. It is not intended for use
in welding by distance.
CAUTION
!
Do not loosen the top hex-headed nut. Damage to the mechanical stop can result.
NOTICE
Turning clockwise will increase the stroke length; turning counter-clockwise will
shorten the stroke length. Adjustment is approximately 0.04-inch (1 mm) per rota-
tion.
Pneumatic System
The pneumatic system is contained within the actuator’s sheet metal enclosure. Refer to Figure
5.1.
The pneumatic system is contained within the actuator and the remote pneumatics box. The sys-
tem consists of :
1.
a primary solenoid valve,
2.
a cooling solenoid valve,
3.
an air cylinder,
4.
a pressure regulator,
5.
and an air-pressure gauge.
6.
down speed flow control valve
The horn’s rate of descent (downspeed) is adjusted at the front of the actuator using the
Downspeed control knob. The rate of ascent is fixed.
