Dual Heating 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、Clean the welding rod surface and insert it into the feeding inlet
3、Press the drive motor switch ( short contact 2-3 seconds). After repeating 2-3 times,
confirm the sound of the drive motor is normal and the speed of welding
rod extrusion is smooth（Extend the heating time if the sound is abnormal or welding rod
is not extruded）
4、The extruded welding rod is not soft or hard, and the smooth surface luster is the
best extruding effect
6、Start Welding
◆ Notes for welding process
1、If the sound of the drive motor suddenly changes or the welding rod 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 welding rod feeding in, immediately release the drive motor switch.
Do not start the drive motor without welding rod
◆ Turn off steps
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
