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.

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 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.
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.
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.
For double impulse automatic sealers, kits include (2) heating elements, (2) PTFE adhesives, and 2ft 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.
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.
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.
