Introduction

W-Series automatic sealers are ideal for high volume continuous poly bag and other thermoplastic sealing. The sealer allows you to keep both hands free for quicker and more accurate sealing. Our W-Series auto sealers can seal polyethylene, polypropylene, saran, nylon, static shielding bags, Mylar up to 30mil in total thickness depending on the model # of the sealer.

Features of the W-Series Automatic Sealers

Your automatic sealer is equipped with a wide range of standard features and capabilities.

Simple to use - no operator training needed Impulse sealing - no warm up time needed Dual mode operation: auto or manual Foot switch allows hands free operation Die cast construction 3 separate control settings for sealing time, recycle time, and congealing time Includes electric foot switch and adjustable work table Equipped with either 2.7mm, 5mm, or 10mm seal widths Option: double impulse sealing with heat on both sealing bars for sealing thicker materials Manufacturer spare parts kit includes: 2 heating elements

How Do W-Series Automatic Sealers Work?

Basic Principles

Our W-Series automatic impulse sealers fire a short burst of electricity through a specially designed heating wire to weld thermoplastic materials together. The Place material on lower length of the seal time will depend on the sealing characteristics of the bag being jaw and activate footswitch sealed. The sealing process is simple: The operator places the bag between the sealing jaws and presses the footswitch to activate the unit. The sealer is equipped with a digital display for easy timer settings. The seal process ends automatically once the preset seal time is reached. The operator retrieves the sealed bag and repeats the process. Bags are sealed repeatedly and uniformly.

Specifications - Single Impulse Sealing

Single impulse automatic sealers are equipped with one heating element (lower sealing jaw).

Operating your Sealer

Assembly Instructions

1. Connect the footswitch to the sealer unit.
2. To install the optional working plate and table, remove screws located at the front of the unit and install the working plate. Adjust working table height according to your bag specifications.

Operation

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. Choose the appropriate mode: manual or auto. Press the green switch towards MAN for manual mode and press the switch towards AUTO for automatic mode

a. For manual operation, place the material to be sealed on the lower sealing jaw and press the foot switch to activate the upper sealing jaw.

b. For auto operation, press the switch towards AUTO to activate automatic sealing. To turn off the automatic mode and return to manual mode, press the switch towards MAN. Auto mode enables the upper sealing jaw to open and close automatically based on the sealing, cooling and recycle settings.

5. Set the SEALING knob to the lowest setting. Always start with a low setting and increase gradually as needed. Thicker bags will need a higher setting.

6. Set the CONGEALING knob setting. The cooling (congeal) setting button determines the congealing time for the sealing. For a high quality seal, seals must be able to cool under pressure. We usually recommend a congeal setting of at least 2x that of the seal setting, but every bag will have variations. Thicker materials will require a longer cool (congealing) time.

7. Set the RECYCLE knob setting. Recycle time determines the amount of time the sealing/congealing cycle will reset.. Recycle time is based on the working speed of the operator.

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 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.

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 W-Series automatic 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 automatic 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.

For single impulse automatic sealers, kits include (2) heating elements, (2) PTFE adhesives, and 1ft long roll of PTFE cover. For replacement kit part #s, refer to your model #. **Please note that heating elements and kits are NOT interchangeable with one another.**

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 (Figure 10, Item #15) found on the plate for PTFE (Figure 10, Item #14) and remove the PTFE cover roller (Figure 10, Item #18). 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.

Figure 7. Loosen multi-star knob to remove the PTFE roller.

Microwswitch Adjustment

Sometimes the microswitch (also called the trigger switch) is moved out of alignment (during shipment or sharp movements) and needs a simple adjustment to get the unit back to proper working order.

Check for the "Click"

The microswitch activates the electrical current to heat the element. When the sealing arm meets the base of the sealer, the microswitch will activate. User should hear the "click" of the microswitch activation. If the "click" is intermittent, this means the microswitch is not triggered and no electrical current is passing through.

How to Make Adjustments

Before operating, turn off unit and unplug.

2. Locate the microswitch which is located at the front of the body. Carefully remove the cover in order to access the microswitch.
