Guiding the device during the welding process
Use the
guide bar (1)
or the machine housing to guide the hot-air welder along the overlap, constantly monitoring
the position of the
overlap guide roller (18)
.
When welding with the hot-air welder, do not force the welder along the seam, lest this causes welding defects.
Check the parameters while welding is in progress
Welding speed, air temperature and air flow range are monitored continuously.
If an actual value deviates from a setpoint of the welding profile or the individual settings, this is shown in the
working display (33)
.
On completion of the weld, disengage the nozzle using the
lever (10)
to the stop. This retracts the
hot-air blower
(9)
and stops the drive.
Then swing the
overlap guide roller (18)
upwards and use the
lifting device (5)
to lift the hot-air welder up.
Actual value corresponds to
the setpoint.
The air temperature's actual
value is lower than the set-
point.
The heating up process is
signaled by flashing; the arrow
points upwards, the progress
bar visualizes the temperature
relative to the setpoint tempe-
rature value.
The air temperature's actual
value is
higher than the setpoint.
The cooling-down procedure
is signaled by flashing; the
arrow points downwards, the
progress bar visualizes the
temperature relative to the
setpoint temperature value.

Turning off the device
• Use the
Heating on/off key (28)
to turn off the heating.
• The text “Heating off?" appears on the display. After the "e-Drive” key has been
pressed, the device switches into cool-down mode (see Cool-Down Mode).
• The blower switches off automatically after approx. five minutes.
• Now turn off the device with the
main switch (11)
and disconnect the
power supply
cord (3)
from the electrical network.
• Wait until the device has cooled down.
• Check the
power cord (3)
and plug for electrical and/or mechanical
damage. Damaged plugs and extension cables must not be used due to
risk of an electric shock.
• Use a brass wire brush to clean the
welding nozzle (8)
.
