During welding
• During the welding process, the hot-air welder can be guided along the overlap using the
handles (2)
, the
clamping lever (4)
, or the optional guide bar.
• The welding speed, air volume, and air temperature can be adjusted at any time during welding (see Chapter
Setting the speed, temperature, and air volume).
Finishing welding
• Unlock the
clamping lever lock (5)
and open the
clamping lever (4)
shortly before the end of the welding
seam. The
upper drive/pressure roller (9)
and the
lower drive/pressure roller (11)
must never run in
contact with one another.
• Next, pull the lever for the
hot-air blower lock (18)
, guide the
welding nozzle (15)
away from the overlap,
and swivel the
hot-air blower (19)
into the park position.
• Make sure that the lever for the
hot-air blower lock (18)
engages in the park position.
•
Caution:
If the heating is switched on but the device is not welding or if the device is in Cool down mode, the
welding nozzle (15)
must be in the park position. Otherwise, the device may become damaged.

and disconnect the
power cord
(1)
from the electrical network.
• Wait until the device has cooled down.
• Check the
power cord (1)
and plug for electrical and/or mechanical
