Commencing welding
Risk of burning
Do not touch heating element tube and nozzle when they are hot. The device should always be
allowed to cool down first. Do not point the hot air flow at people or animals.
• Once you have set all welding parameters in line with your requirements, start the
heating and the drive.
• Use the
Heating On/Off (24)
key to start the heating and the
Drive On/Off (25)
to
start the drive. The
Heating On/Off (24)
key must be held down for 2 seconds.
• As soon as the heating has been switched on, an acoustic signal sounds, the status
LED lights up, and "Heating on" appears briefly on the display. You will see a dynamic
display of the current air temperature with a progress bar (setpoint and actual value)
on the display.
• Make sure that the welding temperature has been reached before commencing work
(heating-up time is 3 − 5 minutes).
• Insert the hot-air welder into the overlapping plastic sheets.
• Pull the lever for the
hot-air blower lock (18)
, lower the
hot-air blower (19)
, and
guide the
welding nozzle (15)
between the overlapping sheets up to the stop. Make
sure that the lever for the
hot-air blower lock (18)
engages in the welding position.
• Close the
clamping lever (4)
so that the
clamping lever lock (5)
engages.
• In the
status line (30/31)
, the file number is displayed alternately in the line voltage
display.
Moving parts must not be touched.
There is a risk of inadvertently becoming caught and being pulled in. Do not wear articles of clothing
such as scarves or shawls. Tie up long hair or protect it by wearing headgear.
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 during welding).
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
hot-air blower (19)
must be in the park position. Otherwise, the device may become damaged.
