Introduction
W-Series Foot sealers are foot sealers ideal for high volume poly bag and other thermoplastic sealing.
The sealer allows you to keep both hands free for quicker and more accurate sealing. Our W-Series foot
sealers can seal polyethylene, polypropylene, saran, nylon, static shielding bags, Mylar up to 10mil in total
thickness.

How Do W-Series Foot Sealers Work?
Our W-Series Foot impulse 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 footboard to activate the unit. The operator retrieves the sealed bag and
repeats the process. Bags are sealed repeatedly and uniformly.

Operating your Sealer
Assembly Instructions
Figure 2.
1. Position the pedestal on the floor standing upright.
2. Mount the complete sealer head to the top of the pedestal and attach with four screws.
3. Bring the upper jaw down and position the small pulling pole/plate set through the pressing
spring.
4. Gently push the upper jaw to meet the lower jaw. While jaws are compressed, reach under the
unit and hook the pulling pole onto the small pulling pole/plate set.
5. With jaws still compressed, lift up the foot pedal to a 45˚ angle and slide the metal foot pedal rod
onto one of the two pre-molded slots. This will create tension on the foot pedal and cause the
pedal to stand upright at 45˚.
6. Sealer is now ready to operate.
7. To install the optional working plate and table, remove the screws from bottom sealing jaw and
install the working plate and table.

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 (110V).
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 under the upper jaw and press down on the foot board gently, but
firmly. The red light will turn off when sealing time is complete.
6. When red light turns off, keep pressing the foot board 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.

the heating element. A worn PTFE adhesive can cause the heating element to break.
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. Occasionally check the condition of the silicone rubber for wear or burns. A damaged silicone
rubber will affect the quality of the seal.

Maintenance
The following maintenance procedures should be followed to ensure the longevity of your W-Series foot
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 W-Series Foot 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 adhesives,
and 1ft long roll of PTFE cover. 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 screws on the PTFE cover plate (Error! Reference source not found., Item #11a).
2. Remove the heating element cover (Error! Reference source not found., Item #23).

3. Lift up the PTFE cover to expose the heating element (Error! Reference source not found.,
Item #12).
4. Remove the heating element by lifting off the eyelets of the heating element from the mounting
spring on both ends (Error! Reference source not found., Item #18).
5. Peel off the PTFE adhesive under the heating element.
Installing New Replacement Parts.
1. Remove the backing of the liner found on the PTFE adhesive.
2. Apply it to the sealer’s sealing platform. The PTFE adhesive must always extend past the sealing
platform by approximately ¼” to ½” on both ends. Bend down the excess on both ends. (The
PTFE adhesive acts a barrier between the metal body and the heating element. Never allow the
heating element to come in direct contact with the sealer’s body because it will damage the timer.)
3. Place a new element on top of the PTFE adhesive by fitting one eyelet of the heating element on
one mounting spring followed by the other mounting spring. Using a screwdriver to flex the
mounting spring inward will ease the placement of the element on the mounting spring. Check
the elements to ensure it is tight and intact.
4. Cut off any worn out PTFE cover. Ease out enough footage of PTFE cover to cover the heating
element and extend to the front of the PTFE cover plate.
5. Tighten the screws to affix the PTFE cover plate.
6. If a whole roll of PTFE cover needs to be replaced, loosen the multi-star knob (Error! Reference
source not found., Item #10a) found on the plate for PTFE (Error! Reference source not
found., Item #10b) and remove the PTFE roller (Error! Reference source not found., Item
#11). Tape one end of the PTFE cover to the rod and roll up the entire piece. Position the PTFE
cover and rod using the plate for PTFE. Ease out enough footage of PTFE cover to cover the
heating element and extend to the front of the PTFE cover plate.
