•
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).
•
Mount preheat nozzle
- Select and mount the preheat nozzle (4)
required for the specific weld geometry.
- Observe spacing A = 5 mm.
- Tighten the preheat nozzle using set screw
(25.1) or mushroom head screw (125.22).
Table: Preheat nozzle
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
without air supply. Otherwise the unit may suffer
severe damage.
•
CAUTION Before plugging in the mains
connector, check that the drive unit is not set to
continuous 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
temperature settings, see page 12.
•
The hand extruder will reach its operating
temperature after about 10 to 15 minutes.
