5.5 Checking the temperature of the extrudate and the prewarming air
• The temperature of the extrudate and the hot air flow must be checked regularly during extended periods of
welding work:
Fast-indicating electronic temperature probes with suitable temperature sensors must be used for this purpose.
You must identify the highest temperature in the hot air flow between the nozzle outlet level and a depth of 5
mm. During extrudate measurement, the measurement sensor in the welding shoe must be inserted into the
middle of the strand.

5.6 Replacing the welding shoe
• The welding shoe must be replaced while the device is warm.
5.7 Welding direction
• Detaching the
clamping screws (18)
allows the
welding shoe (8)
to be rotated freely to the required
welding direction.
• The
clamping screws (18)
must then be retightened
well again.
• Removal
– Remove the
welding shoe (8)
with the
welding shoe holder (20)
by detaching the
clamping screws (18)
from the
extruder nozzle (22)
.
– Every time the welding shoe is replaced, clean the
extruder nozzle (22)
by removing any welding residue from
it and make sure that it is screwed in tightly.
Note: left-hand thread
– Remove the
welding shoe (8)
by detaching the
fastening screws (21)
from the
welding shoe holder (20)
.
• Mounting
– Mount a
welding shoe (8)
that is adapted for the welding rod on the
welding shoe holder (20)
using
fas-
tening screws (21)
.
– The
welding shoe (8)
and
welding shoe holder (20)
must be tightened well using the
clamping screws
(18)
.
