Converting an FP-200 Swirl Gun
to an FP-200 Extrusion Gun
WARNING: Allow only qualified personnel to perform the
following tasks. Observe and follow the safety instructions in
this document and all other related documentation.
The Nordson FP-200 gun, when combined with the appropriate
balance-assist devices, allows the operator to maintain a neutral wrist
position while manually applying hot melt adhesives and sealants to
horizontal substrates. Two versions of the FP-200 gun are available:
extrusion and swirl. Extrusion guns can meet a wide variety of bead
deposition requirements while swirl guns permit exceptional control of
spiral pattern density and size.
Nordson offers two conversion kits: One to convert an extrusion gun to a
swirl gun and one to convert a swirl gun to an extrusion gun. This
instruction sheet contains the procedures for converting a swirl gun to an
extrusion gun.
NOTE: This conversion kit is configured to convert FP-200 gun
Part Number (P/N) 234 896 (swirl gun) to P/N 234 897 (extrusion gun).
It does not accommodate any other FP-200 gun part numbers.
This instruction sheet contains the following procedures:

WARNING: Hot! Risk of burns! Hot applicator parts, splashed
hot melt material, and hot gun surfaces can cause severe
burns. Wear long-sleeved, heat-protective clothing, safety
goggles, and heat-protective gloves. Hot melt material may be
released forcefully.
WARNING: Risk of burns. System or material pressurized.
Air trapped in hoses and guns can spit out molten adhesive that
can cause severe burns. Failure to relieve hydraulic pressure
can result in serious burns. Relieve hydraulic pressure when
instructed to do so.
WARNING: Even when switched off, Nordson applicators,
hoses, and guns contain electrical potentials that can cause
death. Disconnect and lock out line voltage to the applicator
when instructed to do so.
1. Relieve hydraulic pressure (refer to the Relieving Hydraulic Pressure
procedure in the FP-200 gun product manual).
2. Switch the applicator circuit breaker to the OFF position.
3. Disconnect and lock out electrical power to the applicator.
4. Shut off the air supply to the gun.
5. Remove the heat shield from the existing gun as follows:
a. Remove the auxiliary guide handle.
b. Disconnect the extrusion and swirl air lines from the service block
and air manifold.
c. Remove the heat shield.
d. Reconnect the extrusion and swirl air lines. Do not reinstall the
auxiliary guide handle.
6. Remove the existing gun from the suspension system by
disconnecting the hose hydraulically and electrically and by
disconnecting the air line.

CAUTION: The kit for converting a swirl gun to an extrusion
gun does not include a heat shield. To comply with
Underwriter’s Laboratory (UL), Canadian (C-UL), and
Conformité Européenne (CE) standards, heat shield
P/N 234 970 must be used on the converted extrusion gun.
The swirl gun heat shield is 19 mm (3/4in.) longer than the
extrusion gun heat shield and could obstruct the operator’s
visibility of the adhesive’s point of application.
Follow this procedure to convert an FP-200 swirl gun to an extrusion gun.
Figures 1 and 2 identify the components referred to in the procedure (for
clarity, the heat shield is not shown).

follows:
a. Lubricate the new module’s o-rings.
b. Wipe off any hot melt material on the service block, especially
around the air passages.
c. Apply PTFE paste to the two module socket-head screws.
CAUTION: Do not overtighten. Overtightening can strip the
threads.
Fig. 6 Installing the New Module
d. Use the socket head screws to secure the new module to the
service block. Torque the screws to 30 in-lb.
NOTE: For best results, torque the screws again after the applicator
reaches operating temperature.
NOTE: Nozzles must be ordered separately. Refer to Section 5,
Parts.
7. Install the extrusion gun heat shield as follows:
a. Disconnect the extrusion air line by unthreading the tube nut
at the male connector on the service block.
b. Wrap the cover around the module and service block and
fasten it.
c. Reconnect the extrusion air line.
8. Reinstall the auxiliary guide handle.
9. Go to Section 4, Restoring the System to Normal Operation.
Use this procedure to restore the applicator and converted gun to normal
operation.
1. Reconnect the gun to the suspension system by reconnecting the gun
and hose hydraulically and electrically, then reconnecting the gun to
the air supply.
2. Restore electrical power to the applicator.
3. Move the applicator circuit breaker to the ON position.
4. Let the unit and hose reach operating temperature.
