Use
This
polystar®
impulse generator 120 GE in combination with the
polystar®
welding tongs can be
used to safely seal all standard thermoplastic films (e.g. polyethylene) as well as composite films in
a tube and bag shape.
Max. PE film thickness:
2 x 0.30 mm
Seal width:
3 mm
Seal length (depending on tongs):
150 mm
200 mm
300 mm
400 mm
600 mm

Start-up and operation
Position the
polystar®
impulse generator with the welding tongs so as to allow ergonomic
working. Furthermore, the stability of the impulse generator must be guaranteed at all times.
Plug the connector for the welding tongs into the output socket on the front of the impulse
generator. The connector must be heard to lock into place.
Plug the impulse generator's mains plug into the wall socket.
Switch the rocker switch (green) on the front of the device on.
Turn the metal knob to position "1" on the scale. The sealing time is infinitely variable.
Take the welding tongs in your hand. Press the handles together to open the strip-heater carrier.
Place the film to be sealed between the strip-heater carriers (jaws) and close the tongs. To trigger
the sealing impulse, press the green push button on the upper handle of the welding tongs with
your thumb. The green LED comes on. Keep the push button pressed until the green LED goes
out.
The sealing impulse ends when the green LED goes out. The cooling phase begins immediately
after this, during which the film material must be left to cool down under pressure. The welding
tongs should not be opened beforehand.
The cooling phase should be counted in seconds by the user and should be at least 3 seconds.
The sealing process is completed at the end of the cooling phase.
Now open the welding tongs and remove the sealed film material.
If no satisfactory result is found when checking the seam, turn the metal knob for the sealing time
one setting higher. You may have to repeat the procedure several times.
Note:
in order to achieve a good seam, do not set the sealing time higher than is
necessary. Even though a higher setting can also produce good results it places too
much load on the heater element. This in turns leads to premature wear.
