Application
• Overlap welding of roofing membranes made of PVC, TPO, ECB, EPDM, CSPE for basic weld seams.
Can also be used in areas close to edges and on uneven surfaces.
• Overlap welding of sheets and coated fabrics
Please read operating instructions carefully before use
and keep for future reference.
Incorrect use of the hot air tool can present a fire and explosion hazard
especially near combustable materials and explosive gases.
Do not touch hot welding nozzle and welding plate as they can cause burns.
Allow the tool to cool down. Do not point the hot-air flow in direction of people
or animals.
Danger to life when opening the device as live components and connections are
exposed. Unplug the line/mains plug from the plug socket before opening the device.
Warning
Connect tool to a receptacle with protective earth terminal. Any interruption of
the protective earth conductor inside or outside the tool is dangerous!
Use only extension cables/cords with protective earth conductor!
For personal protection, we strongly recommend the tool be connected to an
RCCB (Residual Current Circuit Breaker) before using it on construction sites.
FI

welding nozzle (9), the drive sensor (6) adjustment is possibly incorrect
Action
• Set drive sensor (6) as follows:
– Turn off main switch (3)
OFF
– Remove drive sensor covering (32)
– Lower hot-air blower (8) and move as far as the left limit stop
– Locking lever (11) must latch in
– Loosen locking screw (7) for drive sensor
– Slide drive sensor (6) on tool holder (10); IMPORTANT: Sensing distance 0.2 – 0.5 mm
– Tighten locking screw (7) for drive sensor
– Mount drive sensor covering (32)
– Move out hot-air blower (8) as far as limit stop and swivel up
– Check function
If the drive motor still does not start automatically, the service centre must be contacted.
Operating preparation
Joining force
• Before putting into operation, check power supply cord (1) and connector as well as
extension cable for electrical and mechanical damages.
• Move lower guide bar (26) into the required position using clamping screw,
lower guide bar (31) and upper guide bar (27) using clamping lever, upper
guide bar (28)
• Clip strain relief of power supply cord (1) in holder (29)
• Check the basic setting of the welding nozzle (9) (ex works illustration B and C)
• Transport setting
– Swivel the guide roller (18) upwards
– Release the transport roller (16) by raising the guide bar (27)
– Push the transport roller (16) by applying a little pressure to the shift spring (19)
to the left until it stops (illustration D)
– Position the hot-air blower (8) by pulling the locking lever (11) and swivel it up
until it locks
Connect tool to rated voltage.
Rated voltage stated on the device must correspond to line/mains voltage.
Extract hot-air blower in case of power breakdown.

Perform a test welding according to the welding instructions of the material manufacturer and the
national standards or guidelines. Approve the test welding.
•Set welding parameters drive, heating and blower (chapter 1, Work mode)
•Welding temperature must be reached (heating up time approx. 3-5 min)
• Pull locking lever (11), lower hot-air blower (8) and move in welding nozzle (9) between the overlapping
sheets as far as the limit stop; drive motor starts automatically
No automatic start, see Drive sensor adjustment section
• Machine can be started manually with the controls (4) Drive and e-Drive
• The automatic hot-air welding machine is guided along the overlap at the guide bar (27). Guide the automatic
hot-air welding machines without pressure onto the guide bar (27) during welding. Pressure on the guide
bar (27) can lead to welding errors. Observe position of the guide roller (18)
• After the welding pull locking lever (11), move out hot-air blower (8) as far as the limit stop and swivel up
to the latching point
• After finishing the welding work, use e-Drive (press 2 x) to switch off heating
In this way, the welding nozzle (9) is cooled down and the blower automatically switches off after
approx. 4 minutes (section 1.8, Cooling down)
• Turn off main switch (3)
OFF

230 Disconnect power supply cord (1) form the line/mains.
• Clean welding nozzle (8) with wire brush (33)
Device positioning
•Lift automatic hot-air welding machine applying pressure onto guide bar (27) and move to weld position
•Take welding plate (34) from holder and position according to Illustration E
WARNING: The welding plate (34) may only be removed from the holder and positioned if the welding
nozzle (9) has cooled down.
•Release the transport roller (16) by lifting it with the guide bar (27)
•Push the transport roller (16) to the left until it stops by applying light pressure to the shift spring (19)
•Swivel the guide roller (18) down
•The guide roller (18) should be set parallel to the edge of the pendulum roller (12) (see illustration F)
•Do a test run
•To correct the tracking, adjust the adjustment screw for tracking (13) (see illustration G and H, and the function
notes on the automatic hot-air welding machine)

1.1 Setpoint display (after switching on the device)
Main switch (3) ON
• After switching on the device, the values last set appear on the display (5) (Fig. 3).
• Heating, plower and drive are switched off in this menu.
• The user can use the controls (4) here to perform all settings which are described in
the following chapters.
• If, however, the heating element temperature is higher than 80°C when switching
on, the display will immediately change to the Cool down mode (section 1.8, Cooling
down) in which the blower is always operated at full power, thus cooling down the
welding nozzle (9). It is possible to change back to Work mode from this mode at
any time.
• If the heating element temperature reaches 60°C during cooling down, the blower will
continue to operate for 2 minutes and then switches off automatically. The display (5)
changes back to the Setpoint display (Fig. 3).
• Turning the e-Drive to Profile allows various welding profiles to be selected
(Fig. 4; section 1.7, Selecting profiles).

1.2 Work display
• Pressing the e-Drive starts the heating and blower, and the
Setpoint display changes to the Work display.
• When the welding nozzle (9) is heating up, this is indicated on
the display (5) with progress bar and arrow (up) together with
the actual value of the welding temperature (flashing).
• If the mains voltage is outside (+/- 15%) the specified nominal
voltage (200 V, 230 V, 400 V), this is displayed flashing with the
symbol and the measured undervoltage/overvoltage.
If the air volume is less than 100 %, the percentage indication
changes with the symbol.
The welding result can be affected, depending on the undervoltage/
overvoltage.
• If no button is pressed after a definite time (welding nozzle (9)
NOT in welding position), the Standby menu is displayed (section
1.9, Standby).
• If the welding nozzle is not swivelled in, the menus Cool Down (section 1.8, Cooling down) or Profiles
(section 1.7, Selecting profiles) can be selected by turning the e-Drive .
• If the welding nozzle (9) is swivelled in, the two menu items disappear on the display (5)
and can no longer be selected.
• If the welding nozzle (9) is cooling down, this is indicated with filled out progress bar and arrow
(down) as well as flashing actual value of the welding temperature on the display (5).
