MS-350 NP Operating Instructions Ver 4.02E
12
●
The MS-350 NP series is an impulse sealer
Do not become
alarmed if the sealing area does not become hot after
the power switch
is turned ON. The machine has not malfunctioned.
The sealer uses an
impulse method so the heating
element will not become hot just by
plugging the unit in or turning the
power switch to the ON position.
The heater will only become hot for
an instant when the heating
process is in operation. However, after
extended periods of use, the
sealing area may become hot.
●
Should an abnormality occur in the temperature sensor
The heating section is controlled by a temperature sensor mounted
directly at the seal surface. Should the tip of this sensor slip off the
heating element the machine will fail to function properly. When
replacing the heating element and other routine maintenance parts, take
great care to ensure that the temperature sensor is correctly placed (in
direct contact with the heating element.)
