Mount welding shoe
- Select the welding shoe required for the
specific weld geometry or machine a welding
shoe blank to the required geometry.
- Observe DVS 2207 Guideline, Part 4 for
machining welding shoe blanks.
- Mount welding shoe to the hand extruder in
the position required for welding.
Observe welding direction!
Tighten set screw (25).
•
The welding shoe including preheat nozzle can
be rotated through 360° by releasing the set
screw (25). After rotating the welding shoe, tigh-
ten set screw (25) to fix the welding shoe in place
for the welding operation.
Care must be taken to ensure that the preheat
nozzle provides intensive and uniform preheating
(melting) of the base material over the entire joint
width at as low a hot air temperature as possible. For
larger weld seam widths, a wider preheat nozzle is
available as an accessory.
5.3 Starting the hand extruder
Observe section “Safety“.
•
CAUTION Never operate the hand extruder with-
out air supply. Otherwise the unit may suffer se-
vere damage.
•
CAUTION Before plugging in the mains connec-
tor, check that the drive unit is not set to continu-
ous operation.
CAUTION The hot air hood must be in place.
•
CAUTION Start external air supply for MEK hand
extruder.
•
CAUTION Plug in mains connector.
•
CAUTION In the case of the MAK hand extruder
with integrated air supply, the blower must start
automatically.
•
CAUTION Once air exits the preheat nozzle (4),
the heating systems for the air/melt temperatures
may be activated.
•
For the operation of the temperature controller,
see section 5.5 “Set temperatures“. For tempera-
ture settings, see page 12.
•
The hand extruder will reach its operating
temperature after about 10 - 15 minutes.
