Hand extruder
Application
Hand extruder for welding thermoplastics from PE and PP filler rod with a diameter of 4 and 5 mm (other materials on enquiry) in the construction of containers, apparatus, pipelines and storage sites.
Electroconductive material (e.g. PE-EL) may not be welded.
Warning
Danger to life! Danger to life when opening up the tool, as live components and
connections are exposed. Before opening the tool, unplug from the mains supply.
Electrically conducting material (e.g. PE-EL) must not be welded.
Fire and explosion hazard with incorrect use of the hand extruder (e.g. overheating of the material), especially near combustible materials and explosive
gases.
Danger of getting burned! Do not touch exposed metal parts and escaping
plastizised material. Do not point the hot air flow and escaping plastizised
material in the direction of people or animals.
1
Connect the tool to a mains socket with protective earth. Every interruption
of the protective earth inside or outside of the tool is dangerous!
Only use extension cables with protective earth conductor.
Cross-section of conductor min. 3 × 4mm2
Use ear protection.
Caution
120
230
FI
The voltage rating stated on the name plate of the tool must correspond to the
mains voltage.
In case of a power outage, the main switch and the drive must be switched off
(loosen lock).
For personal protection on building sites we strongly recommend the tool to be
connected to a RCCB (Residual Current Circuit Breaker).
The tool must be operated under supervision.
Heat can ignite flammable materials which are not in view.
The machine may only be used by qualified specialists or under their supervision. Children are not authorized to use this machine.
Protect tool from dampness and wet.

Operating
Working environment / safety
The hand extruder must not be used in inflammable environments or where explosion hazards
exist. Ensure stable positioning during operation. The connection cable and the welding rod
must remain unimpeded and must not hinder the user or others during operation.
Rest the hand extruder on a fireproof surface! Hot metal parts and the hot-air jet must have sufficient clearance from the surface and walls.
Handle Adjustment
1. Loosen the clamping by turning the handle (6) in counterclockwise direction.
2. Adjust handle (6) to the requested working position.
3. Tighten handle clamping again by turning handle (6) in clockwise
direction.
6
Workplace
When not welding, the drive should be switched
off with the drive on/off switch (2).
Place the hand extruder on a stable, fire
resistant base, as shown in the illustration.

If an extension cable is used, it should have a cross section of at least 3 × 4mm2 and must be permitted for the place where it is being used (e.g. outside) and labelled accordingly.
When using a power set for power supply, the nominal power rating for the power set is: 2 × the
nominal power rating of the hand extruder.

After switching on with the main switch (1), press any key on the operating unit (32). The device then
heats up to the last ideal temperature set. When the ideal temperature is reached, a counter on the status
display counts back from 30 seconds to zero. After this start-up process is complete, the device is ready
to weld (status Ready*). The hand extruder takes around 5 minutes to reach its temperature range. If
the power is only turned off for a short time, the start-up process does not need to be repeated.

In the operating window, the following parameters can be selected with the Select key (28) and changed in their
values with the Up key (29) and Down key (27).

Adjusting the Output Capacity
Due to the seam form, the output capacity and the pre-heating period can be matched to each other.
• Pre-adjustment at the display
– By pressing the select key (28), set the cursor to the «SPEED» position.
– Specify the maximum output value (60 to 100) via the up key (29) or down key (27) (indication via the
bar display for drive (22).
• Fine-adjustment during the welding procedure
– By turning the potentiometer (3), the output capacity of the maximal set output value (e.g. 85) can be
reduced to the minimum.
Beispiel

The output capacity depends on the thickness of the welding wire. If the welding output is too high with the output
display «60» and the potentiometer is set to «minimum», the next smallest welding rod thickness must be selected.

Setting the PLAST and AIR temperatures
• Set the cursor to the «PLAST» or «AIR» position by pressing the Select key (28).
• Set the temperature value with the Up (29) or Down (27) keys.
Monitoring the welding parameters
The actual and ideal values of the AIR and PLAST temperatures are constantly
monitored. If an actual value deviates from the relevant ideal value (value is
outside the range of tolerance), this will be indicated by a change in status on
the status display of the drive (30). If necessary, the drive motor will be
temporarily disabled. When the actual and ideal values of the AIR and PLAST
temperatures are within the range of tolerance again, the message «Press any
key» will appear on the status display of the drive (30). Any key on the operating unit (32) must be pressed to release the drive motor again (preventing
the device from being started up accidentally). The possible status display and
the ranges of tolerance are shown in the following graphic and table.

Troubleshooting
Error messages
An error occurring is shown in the status display (30) (e.g Err04 Motor is overheated).
Display ErrXX
When an error occurs, the heating units for AIR and PLAST, as well as the drive motor, are switched off immediately!
Should this not take place, the tool must be disconnected from the mains supply immediately!
Further procedure with status display (30) ErrXX
• Note down the error code
• Disengage the drive locking device (4) and release the drive on/off switch (2).
• Switch off the main switch (1).
Start using the tool again under supervision and ensure that the extruder is not overheated from
the outside.
• Eject the remaining plastic from the screw if possible.
• Should the error reoccur, the tool should be sent to the Service Centre to be checked, specifying the error
code.
The following errors are recognised by the tool:
Display
Err01
Err02
Err04
Err08
Err10
Err40
Type of fault
Overheating of the air or defective temperature probe
Overheating of the plastic welding material or defective temperature probe
Overheating of the motor winding, motor is overheated
Overheating of the heating element, AIR or failure of the blower motor
Overheating of the electronics
Short circuit of the PLAST temperature probe
Several errors can occur at once e.g. Err02 and Err04 Display: Err06 !
Further combinations are displayed with the letters A, B, C, D, E and F.
e.g. Err08 and Err02 Display Err0A !
Drive overheating protection
If the drive is overheated by external influences or because the PLAST temperature
is too low, the internal temperature protection of the drive switches off (see Err04 ).
Accidental start-up protection for the drive
The drive motor is protected against accidental start-up after errors, e.g. overheating Err04 . The message «Press
any key» appears in the status display of the drive (30) while the drive motor is disabled. After the error has
been corrected, press any key on the operating unit (32). The message «Press any key» disappears from the status display.
Welding may continue.
