Operation
Ⅳ.
1. Put the extruder on the shelf and install the handle, connect the power supply.
2. Press the "POWER" button to start the green control box, press "▲" and "▼" button to
set a wanted temperature value (temperature is adjustable from 300 ℃ to 420 ℃
when welding the HDPE). Pre-heating the extruder for 30s, until the first lamp on the
panel turns to green which means the temperature has reached to setting value. Then
operator can start to weld.
3. If the third lamp is on which means the heating temperature is higher than minimum
melting temperature, the motor fuse will open automatically. If the third lamp is not light
up which means the temperature is lower than minimum melting temperature, the motor
will lock automatically; meanwhile the motor will power-off automatically to prevent the
wrong operation. The minimum melting temperature can be adjusted, default value is
300℃, please contact manufacturer if you want to change the default temperature.
4. Press "POWER" button to start the hot air gun, press "▲" to raise and press "▼" to
turn down temperature. The hot air gun knob on the back of heat gun can be used to
adjust the air volume (0-9 grades adjustable).
5. Put the welding rod into suitable feed inlet, press the motor trigger. You could adjust
the motor speed control knob "A to G" to adjust the speed.
6. Adjusting the temperature and speed to ensure the welding rod is melting and
extruding perfectly when actual operation.
7. The operator needs to press the hand extruder on welding seam during operating, to
make sure the melting material can be bond well on seam.
8. The key point of setting warm-up hot air temperature and hot air volume depends on
welding strength and speed. Generally, the working temperature of hot air gun is
between 300 ℃
to 400 ℃ . If fast welding speed is needed, set higher heating
temperature accordingly is necessary.
9. Keep blowing cold air to cool down the hot air gun and extruder for few minutes before
turning off the hot air gun.
10. Make sure the welding rod is extruded totally before turning off the hand extruder.
Then clean out the materials on the air outlet.
