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.
Pneumatic System
The pneumatic system is contained within the actuator and the remote pneumatics box.
The system consists of:
• Primary solenoid valve
• Cooling solenoid valve
• Air cylinder
• Pressure regulator
• Rapid traverse valve
• Downspeed flow control valve
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 rotation.
