For both types of hand extruder, the following pa-
rameters can be freely selected:  

 

welding rate, 

hot air temperature, 

melt temperature and throughput; the melt 
throughput can be controlled downward from the 
maximum value,  
firstly by using 4 mm instead of 5 mm welding 
rod and, secondly, by reducing the speed using 
the rotary button on the Powerbox or the fine-
tuning button of the drive.  
 

CAUTION  Too low a speed will cause a risk of drive 

overheating! 
 

Driven by a powerful electric motor (1), the welding rod (2) 
is fed into the extruder (3) and granulated by the extruder 
screw in the process. The screw forces the granulate into 
the extruder nozzle, melting it into a homogeneous, com-
pletely plastified mass. As the molten material exits the 
extruder nozzle, it is moulded by a welding shoe (4) to the 
geometry of the weld seam to be deposited. 
  
Preheating of the base material to be joined is accom-
plished by a preheating nozzle (5) which is supplied from 
an integrated hot air unit (6). Air is supplied either from an 
external compressor or an on-board blower.  
 

Melt and preheat temperatures are controlled sepa-
rately. The setpoint and momentary values are dis-
played concurrently. 

 

The melt temperature must have reached the preset 
start interlock temperature for the startup timer to 
be activated. After the startup timer has timed out, 
the start interlock will be released and the extruder 
can be started. 

 
 

The temperature-controlled start interlock prevents 
the drive from starting if there is still unmolten mate-
rial in the extruder, thus precluding damage to the 
unit.  

 

The output rate is variable so that the preheat tem-
perature can be matched to the weld thickness. 
 

5  Startup and Shutoff  

5.1  General 
In addition to the operating instructions and the na-
tional and local accident prevention regulations ap-
plicable at the place of use, the acknowledged   
 

 

technical rules for safe and proper working practices 
must be observed. 

 

Any working practices posing a safety risk are pro-
hibited. 

 

Before starting / shutting off the hand extruder, make 
sure to carefully read the instructions under section 
“Safety”. 

 

Only trained and qualified personnel may be as-
signed to the operation of the hand extruder. 
 
5.2  Preparation 

  Place hand extruder and Powerbox on a firm 

support and secure them against toppling over.  

 

 
 

  Mount hot air hood                    

 

  Position handle 

Loosen handle (55) and move it to the ideal work-
ing position by pushing it back and forth. The 
handles of these extruder models can also be 
swivelled upward and downward so that the ma-
chine can be operated by both right-handed and 
left-handed persons.  

  Only for MEK hand extruder with external air 

supply: 
Connect the hand extruder to the external air 
source using the hose coupling LW 13 / NM 7.2 
provided for this purpose (quick connect-
disconnect); set air rate to 300 l/min at 0.4 bar. A 
suitable controller with flow metering function is 
recommended for setting the air rate.

                                          

 

CAUTION The supply air must be clean, dry and 

free from oil and water.  

 

Never connect an external air source to a  
MAK hand extruder.
