Introduction
FKR-A Series double impulse portable sealers are lightweight and easy to use anywhere. The sealer is
ideal for sealing polyethylene and laminated foils. Equipped with top and bottom heating elements, our
double impulse sealers can seal thicker thermoplastic materials up to 20mil in total thickness.
Applications include sealing around oddly shaped products including drum, box liners or sealing around
large, irregularly sized objects.
Features of the FKR-A Series Double Impulse Portable Sealers
Your sealer is equipped with a wide range of standard features and capabilities.
Impulse sealing - no warm up time needed
Lightweight and easy to operate
Impulse heat with timer
Available in 8", 12", and 16" seal lengths
Seal width: 5mm (.19")
Manufacturer spare parts kit includes: 2 heating elements
How Do FKR-A Double Impulse Portable Sealers Work?
Our FKR-A Series double impulse portable sealers fire a short burst of electricity
through a specially designed heating wire to weld thermoplastic materials together.
The length of the seal time will depend on the sealing characteristics of the bag
being sealed. The sealing process is simple: The operator places the bag between
the sealing jaws and presses the jaws together to activate the unit. The operator retrieves the sealed bag
and repeats the process. Our FKR-A Series double impulse sealers utilize twin heating element wires, one
on the upper sealing jaw and one on the bottom sealing jaw providing greater heat penetration for sealing
through thicker materials (up to 20mil total thickness).

Operating your Sealer
Important
Read this manual carefully, and make it available to everyone connected with the supervision, maintenance,
or operation of this machine. Additional copies are available at your request. (Contact your distributor for
this information.) Be very careful when operating, adjusting, or servicing this equipment. If in doubt, stop
and obtain qualified help before proceeding.
Installation
Place the portable in the desired location with the required electrical power source available. (See power
requirements.) Make certain that proper electrical wiring is provided to guard against low voltage. If the
voltage is too low, the equipment will not function properly.
Plug the handle to the main base of the machine.
Figure 2. Plug handle to base of machine.
Finding the proper location is a most important function of the initial set-up. One must take several factors
into consideration:
Adequate power source
Relationship to source of product
Relationship to any conveyors necessary to remove finished product
Convenience of operator

Operation
1. Before operating, check the heating element, PTFE cover, PTFE adhesive and the
silicone rubber.
2. Insert the power cord into the correct receptacle (120V).
3. Turn the power switch on.
4. Set the timer knob to the lowest setting. Always start with a low setting and increase gradually as
needed.
5. Place material to be sealed between the jaws. Hold the handle down firmly to activate the sealing
cycle. The timer light will turn off when seal has been completed.
6. When red light turns off, keep holding the handles firmly for an additional 2-3 seconds.
For a high quality seal, seals must cool under pressure. We usually recommend a
congeal setting of at least 2x that of the heat setting but every bag will have variations.
Thicker materials will require a longer cool (congealing) time.
Tips for Successful Sealing
1. If the seal is broken or damaged, decrease the sealing time.
2. If the seal is not fully welded, increase the sealing time.
3. If the sealing material sticks to the sealing pad, decrease the congealing time.
4. If the width of the seal is not perfect or does not match the size of the element, increase the
congealing time.
5. Always keep the sealer clean. Remove any residue found on the platform and PTFE cover. Silicone
spray may be used for this purpose.
6. When replacing the heating elements, always replace the PTFE adhesive under
the heating element. A worn PTFE adhesive can cause the heating element to break. The
PTFE adhesive works as a barrier between the body of the sealer and the element. Never allow the
element to come in direct contact with the sealer body as that will damage the timer.
7. Be sure to turn off the power or unplug the unit before replacing any parts.

Maintenance
The following maintenance procedures should be followed to ensure the longevity of your FKR-A Series
double impulse portable sealer.
Inspection and Cleaning
1. Inspect your machine daily.
2. Use a clean cloth to remove any plastic residue remaining on the PTFE cloth.
3. When replacing the elements, always check the condition of the bottom PTFE tape.
4. Check the condition of the silicone rubber for wear and burns. A damaged silicone rubber will
affect the quality of the seal.
Replacement Kit Instructions
Our FKR-A Series double impulse sealers will require new heating elements and PTFE from time to time.
Heating elements will break through wear and tear. A good rule of thumb is to replace the PTFE adhesive
every time you change your heating element. The PTFE cover prevents the plastic or other thermoplastic
material you are sealing from sticking to the heating element.
Replacement kits are available from your distributor. Kits include (2) heating elements, (2) PTFE Covers,
and (2) PTFE adhesives. For replacement kit part #s, refer to your model #.

To install your replacement kit on your sealer, turn off power and unplug sealer.
Removing Worn Parts.
1. Loosen the four screws on the PTFE cover plate on both sides of the sealer body. Remove the
PTFE cover.
Figure 3. Loosen screws on PTFE plate.
2. Unscrew the cap and nut that are holding the heating element (Figure 4). To remove the heating
element, use a screw driver to press down on the mounting screw which is spring loaded (Figure
5). When you release one end of the element, the other element should release easily.
Figure 4. Loosen the cap and nut holding the heating element.
Figure 5. Remove heating element by pressing down on the mounting screw.
3. Peel the PTFE adhesive from the sealer's body.
Installing New Replacement Parts.
1. Remove the backing of the liner found on the PTFE adhesive.

2. Apply the adhesive to the sealer’s sealing platform. Tuck the adhesive close to the mounting screw
as possible. Note: The PTFE adhesive serves as a barrier between the sealer body and element.
Never allow the element to come in direct contact with the sealer body. A good rule of thumb is
to replace the PTFE adhesive every time you change the element.
3. Hook one end of the element to the mounting screw. Place the sealer on its side so that
mounting screw is touching the table. To attach the element to the other side, press down on the
mounting screw while at the same time use a screw driver to press down on the mounting screw
on the other side of the sealer. Both mounting screws should be held down at the same time and
this will allow you to attach the other end of the element. Attach cap and nut.
4. Replace the PTFE cover.
5. Replace the PTFE cover on both sides. Tighten the screws on the PTFE cover plates when the
PTFE cover is position smoothly on top of the element. Note: The PTFE cover prevents the
plastic or any thermoplastic material you are sealing from sticking to the heating element.
