General Description
Main Switch
This turns the machine on and off.
Hold Switch
This switch locks out the timer; the head will come down but the timer will not work.
The head stays down as long as the foot pedal is depressed. THIS IS A
MAINTENANCE FUNCTION used when changing electrodes to insure that they
are well seated and parallel to the base when tightened.
Auto Switch
Turning this switch to the "on" position will activate the feed system, transporting a
label from the hopper to underneath the electrode, ready for sealing.
Timer
The dwell time can be set by turning the pointer in the center of the dial face to the
desired time.
Air Pressure Gauge/Regulator
Adjustment of air pressure is accomplished by turning the knob under the air
pressure gauge. To raise the pressure, turn the knob clockwise; to lower, turn it
counter-clockwise. When lowering the pressure, allow the needle on the gauge to
drop below the desired pressure, then raise it back to that pressure. The reason for
this is that there is a lag when bleeding air out of the system.
Heat Controls
Electrode and plate head can be set independently. The correct temperature will be
indicated on the control's face. If the control fails to reach this, refer to the heat
control pages provided.
Foot Switch
Depression of the foot switch starts the unit cycling for the time indicated on the
cycle timer. The foot switch should be kept in the depressed state until the press
cycles out and the seal is completed. As the press starts to rise, the food pedal can be
released, allowing the machine to re-set automatically, feeding a label from the
hopper to the electrode, ready for sealing. Removal of pressure from the foot switch
at any time after the start will immediately break the cycle and return the press to
neutral.
