1、The plastic in the extruder must be cleaned before the machine is turned off so as not to
cause blockage and damage the extruder next time
2、After cleaning plastic, set the hot air blower potentiometer to 0 and cool it down
3、Turn off the hot air blower power switch
4、Turn off the control box power switch
5、Cut off the power
Use fireproof mats
Don't direct hot air towards
people or objects

Granules Extrusion Welder Operating Steps
LESITE
◆ Power on
1、Plug in
2、Press the control box power switch and rotate the control box temperature adjust knob
to 320-350℃ （Digital Display）
3、When the digital display temperature reaches setting temperature, delay 180 seconds
before starting the drive motor (Cold Start Protection)
◆ Preparation before welding
1、Turn on the hot air blower power switch, rotate the hot air blower potentiometer to
position 6-7
2、Pour plastic granules into the hooper
3、Press the drive motor switch and press the self-locking button, Confirm the sound of
the drive motor is normal and the speed of granules extrusion is smooth（Extend the
heating time if the sound is abnormal or granules is not extruded）
4、The extruded granules is not soft or hard, and the smooth surface luster is the best
extruding effect
5、Start Welding
◆ Notes for welding process
1、If the sound of the drive motor suddenly changes or the granules is stuck without feeding,
it is necessary to immediately loosen the drive motor switch and check whether the heating
temperature is normal
2、In the case of no granules feeding in, immediately release the drive motor switch. Do not
start the drive motor without granules
◆ Turn off steps
