•
Hold and touch the hand extruder only on
the handles provided for this purpose.

•
CAUTION The melt temperature must have rea-
ched the preset start interlock temperature for
the startup timer to be activated. After the startup
timer has timed out, the start interlock will be re-
leased and the extruder can be started.
In addition to the start temperature interlock, the
brushless drive is equipped with a torque control
which prevents the extruder from starting as long
as the operating temperature is not reached
and/or melting of the extrudate is not complete.
5.4 Welding with the hand extruder
Observe section “Safety” and the data sheet.
General
Welding is to be carried out in accordance with the
guidelines of the German Association for Welding
Technology (Deutscher Verband für Schweißtechnik
DVS).
The parts to be joined and the welding rod must be
clean and dry.
5.4.1 Introducing the welding rod
•
CAUTION The hand extruder is provided with a
bore for introducing the welding rod .
5.4.2 Replacement and aging of welding rod
•
If the welding rod is to be replaced, make sure
that any remaining rod in the hand extruder is
completely removed.
•
For this purpose, operate the preheated hand
extruder with the new welding rod until clean new
material discharges.
•
The DVS guideline also recommends this proce-
dure for hand extruders which have been out of
service for prolonged periods while still being
filled with welding rod.
•
Ensure safe and environmentally compati-
ble disposal of any waste generated!
5.4.3 Welding direction / rate
•
The pressure of the discharging extrudate causes
the welding shoe (and hence, the hand extruder)
to move in welding direction.
•
See DVS Guidelines for the welding rate.

5.4.4 Interruption of work
•
Observe section “Safety“.
Do not leave the hand extruder unattended.
Make sure to maintain the air supply.
•
When interrupting the welding job, switch off the
drive unit and deposit the hand extruder as
shown in the illustration below.
