Before the automatic welder is used, test welds are to be carried out in accordance with
the welding instructions of the material manufacturer and with national standards or guide-
lines. The test welds must be checked.
•
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.
10.4 Welding sequence
1:1
Commencing welding
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.
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 (38)
key to start the heating and the
Drive On/Off (37)
to
start the drive. The
Heating On/Off (38)
key must be held down for 2 seconds.
• The status LED lights up as soon as the heating is switched on. If an arrow pointing
upward appears on the display next to the set temperature, the actual temperature is
increasing.
• 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.
