Impulse sealer
There are four sealing methods depending on your purpose and usage. Sealers
refer to machines in general that seal the opening or loose ends of plastic-

called heat sealers.
Heat-sealing technologies for general use include the following:
1
Impulse sealer,
2
Constant heat sealer
3
Ultrasonic sealer,
4
High-frequency sealer
FUJIIMPULSE’s products are mainly the impulse sealer in the above categories.
An impulse sealer heat-seals objects by sending high current on impulse to a
heater ribbon, equipped on the surface of the heat-sealing blade, to generate
heat that enables thermal-sealing through thermal conductivity. The section to
be sealed is placed between the heat-sealing blades, pressed, and thermal-
fused when current and heat are delivered on impulse* through the heater
ribbon. After the current stops, a cooling process is necessary during which the
pressure is maintained.
* The name is derived from the fact that the current and heat are delivered on
impulse, or instantaneously.
METHOD
(Displayed on the control unit screen)
"METHOD" appears on the liquid crystal screen of FAS-402 series when
operator select the sealing method.
(Sealing only or Seal and Vacuum)
Sealing method generally means "Impulse style", "Ultrasonic style", "High
frequency style" etc.

Sealing only
Only the sealing process is performed. When this operation pattern is selected,
the vacuum function will not work.
Temperature sensor
The temperature sensor directly measures the temperature of the seal area.
Vacuum (manual)

by depressing a foot switch.
Vacuum (timer)
Vacuum is performed to the set vacuum time by timer.
