Manual

General
Please read this manual carefully before using this machine, and retain it for
future reference.
This plastic extrusion welding machine pioneered using of the function of double
independent heating systems, 360-degree rotating welding head, motor cold start
protection, which is applicable to welding HDPE,PE,PP and other hot melt materials.
It plays its most characteristic especially for welding PE membrane. But do not apply
to conductive plastic (PE-EL), otherwise the machine will produce conductive short
circuit.
Replacement of different welding shoe can be applied to:
1. Plastic containers of welding, splicing, etc.
2. Plastic pipe fittings welding, repairing, stitching, sealing, etc. Especially for plastic
pipe with large diameter.
3. Thick plastic film, geomembrane splicing, repairing and so on.
Ⅰ. Notice
1. CAUTION DANGER. Please confirm that the plug has been removed while
disassembling the equipment!
2. Incorrect use of the equipment will result in fire and burns!
3. The voltage on the equipment (220V) must be the same as the main voltage on the
plug, and the supply voltage shall not exceed 10% of the rated voltage of the
equipment.
4. To ensure the safety of users and reliable operation of the equipment, the power
supply should be installed voltage stabilizer and leakage protection device;
5. Do not touch the soldering nozzle and metal case to prevent scalding, and do not
point the hot air to human and animals.
6. Please protect the equipment from moisture.
7. Please focus while operating.

Ⅳ.Operation
1. Put the extruder on the shelf and install the handle, connect the power supply.
2. Turn on the hot air gun power switch, then adjust the temperature control knob,
and set the temperature to the required figure(during preheating you can adjust to the
highest temperature, when formal operation can adjust to the appropriate
temperature). Preheating the extruder for about 3-5 minutes, until the residue on the
welding nozzle outlet get softened, using tools to pick the softened residue out of the
welding nozzle. The length of preheating time needs to be judged according to the
scene. The residue of the outlet of the welding nozzle has not yet softened, which
means that the preheating time is not enough. If the residue become thinning, it
means that the preheating time is too long. The proper preheating time is very
necessary: if the preheating time is insufficient and the forced starting of the extruding
welding gun will cause the motor overload, it will destroy the motor rotor seriously. If
the preheating time is too long, the heat of the outlet will fall back, which will cause
the motor overheated and stopped. The welding rod will be melted before it enters
the extrusion chamber, and the blade cannot be fed.
3. Use right hand to pull the motor switch, and the motor starts to work. If a new
machine has a slight noise, it may be related to the resonance of the machine with
the shelf or the tightness of the parts inside the machine, which does not affect the
normal operation of the machine. If the motor works smoothly and the internal sound
of the feed is disappearing, it is normal. But if the motor works not smoothly, the jitter
is intense, and the noise is aggravated, it indicates that the preheating time is not
enough and the residue inside the gun is not melted out. It is necessary to extend the
preheating time.
4. When the motor is determined to start, it is best to standby for 2-3 minutes. After
that, it can be inserted into the welding rod. According to the plasticizing of the
extruded material, the temperature control knob should be carefully adjusted till the
welding rod in the screw is softened completely.
5. Before put welding rod into the extrusion cavity the rotation rates of motor is lively.

5/8
After feeding welding rod the rotation rates of motor will become heavier, if it
becomes very difficult, please stop immediately, may be the screw heating time is too
short or the temperature is not high enough. Or the temperature is so high that lead to
the cut solder particle has been melt and clinging to the cutting blade to cause the
plugging before it falls into the extrusion gun body. In this case, it is necessary to
remove the Y type extrusion gun body and clean the scrap on the cutting blade to
ensure that the equipment is not damaged normally.
6. Faster welding speed need to higher heating temp. At general condition, the hot air
temperature is between 260 ℃to 450 ℃. Choose suitable hot air temperature is
important during welding.
7. Adjusting the temperature and speed to make sure the welding rod is melting and
extruding perfectly when actual operation.
8. The operator needs to press the hand extruder on welding seam during operating,
to make sure the melting material can bond well on seam.
9. Flat welding shoe and 90-degree welding shoe suitable for different welding ways.
Pls rotate and pull out of the welding shoe or preferably with a little heat and remove
when you need to replace it, do not pull or knock directly.
10. Finishing stage: Extrude all welding rods which inside the cylinder (when the
motor voice getting lighter that means extrude completely), and clean out the welding
materials that on the air outlet. Otherwise it may cause blocked when you use next
time.
11. Shutdown stage: Adjust the hot air gun to cold wind and cooling the heating
element at least 5 minutes before shutdown.
12. It needs to clear out all previous welding rods before next time to starting the
hand extruder up.
13. The service life of carbon brush around 1600 hours, pls note that and replace it
timely.

Precautions for Use (The Content on the Label)
1. Preparation stage: Preheating the extruder on the shelf, carefully check the
power plug and prevent it from falling off.
2. Extrusion gun preheating stage: Preheating the extruder for 3 minutes. Take the
softened residue can be clip out with a nipper plier as standard.
Caution a: If forced to start driving motor in the case of insufficient preheating, it may
cause motor to be burned because of motor over load.
Caution b: When the preheating time is too long and the high temperature of the
cavity makes rod liquefied, it will unable to feed welding rod if the rod is softened and
stick to the blade.
Caution c: When start feeding welding rod, try to feed the rod slowly. After the
feeding speed go on normal and stable, then work at constant speed.
3. Working stage: Pay attention to the working strength of the welding gun. Do not
operate for a long time to prevent the motor from overheating.
Caution: Do not increase the motor speed unilaterally without increasing the heating
temperature. Otherwise, the rotor may be burned down.
4. Shutdown stage: It is necessary to extrude all the welding rod and solder out of
the cavity to prevent the clogging in the cavity of the next use.
Caution: Extrude the residue out of the cavity, adjust the hot air gun to cold wind and
cooling the heating element at least 5 minutes before shutdown.
