

Never touch the heating element(s) with bare hand while the sealer is plugged into a power source,
in operation or just finished operation. Touching heated areas may cause fire and/or severe burns.

 While machine is in operation, do not place fingers, tools, or other foreign objects on or into the

machine. Do not place hands or fingers near pinch points. Do not touch machine while it is in
operation. Perform all procedures carefully and watch where hands and fingers are at all times.

 The sealer is not water resistant or water proof. Spraying down the machine will damage machine

or cause electrical shock. Do not submerge the sealer into water or liquid.

 Do not operate sealer in a corrosive or humid environment.

 Always keep the machine clean, lubricated and in good working condition. Follow any

maintenance and lubrication procedures outlined in this manual. Make sure unit is disconnected
from power source before cleaning.

 NEVER use any accessories or parts from other manufacturers. Machine should not be altered or

modified using parts that are not genuine authorized parts. Doing so will VOID YOUR
WARRANTY.



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.

 Never leave the sealer unattended. Be safe, disconnect the sealer from power source before

leaving work area.

 Always keep out of reach of children and pets.

 Close supervision is necessary when any appliance is near persons with reduced physical, sensory

or mental capabilities or lack of experience and knowledge . This sealer is NOT to be used by
children or by persons with reduced physical, sensory or mental capabilities or lack of experience
and knowledge.

 DO NOT use the sealer outdoors.

 DO NOT use the sealer while under the influence of drugs, medications or alcohol.

Introduction

W-Series double impulse foot sealers are ideal for high volume poly bag and other thermoplastic sealing.
Equipped with top and bottom heating elements, our double impulse sealers can seal thicker
thermoplastic materials up to 20mil in total thickness. Single/double sealing switch selector provides the
sealer with the flexibility to seal different types of materials. The sealer allows you to keep both hands
free for quicker and more accurate sealing.

How Do W-Series Double Impulse Foot Sealers Work?

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. Our W-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).

Assembly Instructions

Figure 2. Double Foot Assembly Diagram

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 (Figure 8, Item #12A)
through the pressing spring (Figure 8, Item #12B).

4. Gently push the upper jaw to meet the lower jaw. While jaws are compressed, reach under the
unit and hook the pulling pole (Figure 8, Item #5). 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.

Maintenance

The following maintenance procedures should be followed to ensure the longevity of your W-Series
double impulse 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 double 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 2ft 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.

2. Remove the terminal assembly block cover (Figure 8, Item #7a).

Figure 3. Loosenscrewson PTFE plate.

Figure 4. Remove heating element cover.

3. Lift up the PTFE cover to expose the heating element (Figure 8, Item #12).

4. Remove the heating element by unscrewing the element screw (apply pressure to the heating
element with your finger while unscrewing the screw to prevent heating element from twisting.)

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 screwing the element in the heating terminal
assembly block. To attach the element to the other side, lift the latch found on the heating
terminal assembly block to push the block inward and securely screw the element to the block.
Check the element to ensure it is tight and intact.

Figure 6. Lift latchon heating block to screw element in place.

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 (Figure 8, Item

#31) found on the plate for PTFE (Figure 8, Item #30) and remove the PTFE roller (Figure 8,
Item #14). 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.
