2. Product Overview
PW602 hand extruder is a new type of hot air welder which imported foreign
advanced technology, well-developed,.It has reached or exceeded the same
type products of oversea, filling the domestic blank. The major components
(hot air gun and drive motor) are made of imported brand-name accessories,
stable performance, long service life; They are two independent systems,one
is for preheating raw material,another is for welding rod extrusion. Reasonable
structure, convenient operation, continuous welding, high working efficiency,
powerful extrusion, to make the weld strength is greatly improved. It is the ideal
product for a variety of thermoplastic welding processing.
This product is with two major components, preheating raw material’s hot air
part and welding rod’s extrusion part. Hot air part with adjustable temperature
controller to heat automatically, and extrusion part with independent
thermostatic heating control system to send hot air independently. It is easy to
adjust extrusion speed and use screw extruding for powerful extrusion
pressure. Using 220V power supply uniformly to weld plastic sheets,tube and
other thermoplastic products,expecially for both ends of large diameter hollow
wall pipe, producing pipe and repairing pipe and so on.

Available welding materials: thermoplastic HDPE, PP, PVDF, especially
PE .Do not apply in a conductive plastic (PE-EL), or cause the machine to
produce a conductive short-circuit.
Replacement of the different welding nozzle, can be applied:
1) Plastic containers’s welding, stitching, etc.;
2) The large diameter plastic pipe’spipe welding, repairing, splicing, sealing,
etc.;
3) The thicker plastic membranes, geomembrane splicing, patching and so on.
Main technical parameters:
PW602 Hand Extruder:
1)Voltage: 220V
2)Power: extrusion system drive motor: 1300W
Heating systems: heating tube 1100W + hot air welding torch 3400W
3) Temperature: adjustable air temperature 20 to 600 ° C
Adjustable plastic extrusion heating temperature is 0 ~ 450 ℃
4)Preheating air volume: 500L/min
5) Welding rod diameter size: Φ3.0mm ~ 5.0mm
3. Operation procedures:
1) Put the hand extruder on the shelf, install the handle, plug in the mains plug.
2) Open the control box switch, welding temperature is generally set at 300 ° C,
when the temperature reach 270 ° C, the motor switches off, you can not start,
when the temperature reaches 270 ° C, the motor switch is turned on, you can
start properly. Open the hot air machine power switch, thermostat knob,
heated a few minutes to operate.
(3) the right hand pull the motor switch, the motor starts to rotate. The new tool
noise, probably it mostly is relevant to the resonance between the tool and the
base or the close of the parts inside the tool.If the motor is very smooth, and
the internal sound disappears after sending welding rods.
4) It is better to re-standby 5 to 6 minutes after ensuring the motor can be
started.Then put welding rod into machine to operate. Adjust the temperature
carefully depending on the thermoplastic case.
5)Motor’s rotating speed is fast without thermoplastic and will become heavier
when sending welding rod, if become very difficult, please stop, probably
screw heating time is too short or low temperature.

6) different welding methods require different welding nozzles, our company
provides a standard nozzle.
7)Need pressure on machine then can be pressurized on the welding seam.
Extruding some plastic material to heat nozzle, then make weld surface not
smooth.
8) Welding speed, extruding,angle, nozzle structure will determine welding
seam’s looking, but the most important thing is air temperature and air volume.
It determine welding ‘s strength. Usually hot air temperature is 260 ~ 400 ℃.
Certainly, the faster welding speed, the higher required temperature.
9)Hot air with the welder moves, It is alright as long as can make the surface to
be welded after the hot air blowing. The higher temperature of the welding is
not the better. Select the correct temperature is very important.
10) Please do not knock when replace the PTFE welding head. It is better to
heat then take down.
11)Hot air motor carbon brush life is about 800 hours, attention to early
replacement, do not wait until the carbon brushes to run out.
12) When shutdown, please circumgyratehot air thermostat knob to the
minimum, a few minutes blowing before they shut down the hot air machine.
13) Retain a little of welding rod when shutdown to avoid extruder screw’s
damage.
14) Clean up welding nozzle when shut down.
4. Product Features
1) Imported hot air welding torch and imported driven system, high
temperature, big torque, long service life, stable performance.
2) Light weight, easy to handle and available to operation at different angles.
3) Big extrusion volume can be welded more than 10mm welding seam.
4) Different welding shoes can be applied to different types of welding.
5) It is used in the tank and pipe and is comply with Part 4 of the DVS standard
(Germany Welding Association).

5. Product warranty
1）This extruder warranty period from the date of delivery for one year.
2) After receiving the extruder, user should immediately check whether the
extruder is in good condition, no comments in two days will be as a complete,
through acceptance.
3）No warranty for damage caused by the following circumstances:
a) No feedback for problems in time or not in accordance with the
requirements to take timely measures to cause serious damage;
b) Willful damage or overload;
c) Demolition, repair and maintenance work without the manufacturers
permission ;
d) To make alterations or install attachments without being approved by the

4) Normal wear and tear is not covered under warranty.
5) No warranty for force majeure (lightning, floods, fires, accidents and other
non-manufacturing business reasons) caused by damage.
6) Above terms shall be invalidated after the warranty period.
5. Safety Precautions
1)Prohibited he extrusion nozzle facing the person or object of any likely to be
scalded when devices work.
2) Stop using the equipment, or start using must ensure that the head nozzle is
not covered with plastic, and if so may result in poor extrusion, resulting in a
backflow or injection, reflux causes the damage, spray may cause burns.
3) When the device is working, any metal part is proibited to touch, otherwise
there will be danger of burns.
4) The device is turned on, there must be supervised, or may cause equipment
damage and cause a fire hazard.
