W-Series Direct Heat Sealers are designed for sealing many different types of thermoplastic materials including: coated aluminum foil, Kraft paper, cellophane, polypropylene, poly-nylon, and other thicker materials up to 20mil in total thickness. Please note that our direct heat sealers would not be appropriate for sealing polyethylene and/or polyvinyl chloride.
Your Direct Heat sealer is equipped with a wide range of standard features and capabilities.
Direct heat sealing / constant heat sealing system Heavy duty all metal construction Table top design supported with anti-slip rubber feet Simple to use - minimal operator training German manufactured temperature controller that maintains the seal bars at a proper temperature providing consistent seal quality Electronic timer (0-6 seconds) to adjust sealing time providing for consistent seal quality Equipped with protector bars around the sealing bars to prevent injury Hands free sealing activated by footswitch Sealing width: 1/2" (15mm) Sealing length: 12" (300mm) Adjustable work table Options: meshed (W-300DAT) or serrated (W-300DATS) sealing bars

Basic Principles
Our W-Series direct heat sealers maintain constant heat in both sealing jaws. Direct heat sealers consume power as long as the sealers remain on thus providing Place material on lower better heat penetration than impulse sealers. The temperature and length of the sealing bar. Activate foot switch to bring seal time will depend on the characteristics of the bag being sealed. The sealing upper seal bar down. process is simple: The operator places material on lower sealing bar of sealer and activates foot switch to bring the upper sealing bar down. Upper sealing bar will release automatically based on timer settings.

Our W-Series Direct Heat Sealers will require new heaters from time to time. There are two heaters found on the unit, one in the upper sealing jaw and one in the lower sealing jaw.
Remove the old heater on either the top and/or bottom sealing jaw. Unscrew the heater loose from the sealing jaw and base of sealer. Remove the thermostat plate to access the other end of the heater. We suggest marking down the exact locations of the connections in order to accurately replace the new heater. Note: In order to the fully remove and install the heater one may also need to separate the head of the sealer from the base.

To install new heater, remove the old heater and crimp on the new heater. Following your marked connections, install the new heater back on the sealing bar and screw to tighten back into place.
