Operation Overview
The SST Switch 3D gun dispenses ribbons of material
onto a substrate. The height and width of the material
bead is dependent on the nozzle selection, flow rate of
the material and the speed of the robot movement. The
size of the bead can also be determined by the size of
the nozzle. See Performance Charts starting on page
40 to help determine settings of the SST Switch 3D
Gun.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection and splashing
fluid, follow the Pressure Relief Procedure when you
stop spraying and before cleaning, checking, or
servicing the equipment.
This procedure describes how to relieve pressure from
the SST Switch 3D Gun. See your supply system
manual for instructions on relieving pressure from the
entire system.
1. Shut off the material supply.
2. Position the SST Switch 3D Gun into a grounded
metal pail to relieve the fluid pressure.
3. Relieve all air pressure in the air lines by shutting off
the Customer supplied bleed valve. See F
4. If the nozzle tip or material hose is clogged or if
pressure has not been fully relieved after following
the steps above, very slowly loosen the customer
supplied material hose from the 1/2 in. BSPP inlet
fitting (604), (see F

Flush the SST Switch 3D Gun
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.
•
Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
•
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Setup
1. With the SST Switch 3D Gun fully primed and cable
connections integrated into the robot control
system, the SST Switch 3D Gun is ready for
dispensing material onto the substrate.
2. Calculate the flow rate by the required height and
width versus the robot speed.
3. Adjust the material control system supplied with the
robot to the required flow rate.
4. Program the robot with the desired nozzle used to
dispense the material. The nozzle must be
perpendicular to the substrate.
5. Run the program and validate the height and width
of the bead.
6. The flow rate, robot speed, and nozzle size can be
adjusted to achieve the desired height and width of
the material bead.
7. Nozzle distance from target can affect the quality of
the bead. The further the nozzle is from target the
more air can be trapped between the bottom of the
bead and substrate.
8. After the correct height, width, and quality of the
bead is confirmed, the SST Switch 3D Gun is ready
for dispensing.
