Operation steps

Step 1: Initialization
The machine retracts the jaws to the fully retracted position and then moves them
forward to the start position. The previous sealer settings are loaded and the tubing
type and diameter are displayed on the LCD display. The machine beeps to indicate
that the initialization step has been completed correctly, and the READY light will
come on. HOT LIPS TUBE SEALER uses position sensors and encoders to provide
feedback on correct positioning. This minimizes the need for realignment.
Step 2: Clamp tubing
The unit closes the jaws to clamp the tubing to a preset thickness. If the GO button
is released before the jaws reach the final position, the closing step is aborted and
the jaws open to the loading position.
Step 3: Heat tubing
If the jaws are in the correct position, the unit initiates heating of the jaws. This is
done to a preset temperature depending on the type and wall thickness of the
tubing.
Step 4: Seal tubing
Tubing is maintained at a preset temperature for a preset time to seal. Then the
fans are turned on to start cooling the tubing.
Step 5: Cool down
The unit is then allowed to cool to a preset temperature. This ensures that the jaws
are safe to touch and that the seal is properly annealed. At the completion of the
cooldown period, the machine will beep and the jaws will open automatically.
Pressing the GO button will reinitialize the unit (Step 1).
