• Once you have prepared the working area and the hot air welder in accordance with the description, connect the
hot air welder to the mains voltage.
• Switch the wedge welder on via the
main switch (19)
.
• Define the welding parameters for drive, air temperature and air volume on the respective
Potentiometer (30,
33, 36)
.
• Now switch on the heating [
Direct heating button (35)
].
Preparing for welding
• Make sure that the welding temperature has been reached before commencing work. The heat-up time is 3 − 5
minutes.
• Now carry out test welds in accordance with the welding instructions of the material manufacturer and/or national
standards or regulations and inspect the results. Adjust the welding profile as needed.
Commence welding
• Pull the
hot-air blowers lock (15) lever,
lower the hot-air blowers (10) and guide the
welding nozzle (9)
be-
tween the overlapping sheets up to the stop.
• The drive motor starts automatically as soon as the
hot-air blowers (10)
are engaged.
Guiding the device during the welding process
• Use the
guide bar (22, 24)
or the
carrying handle (5)
to guide the hot air welder along the
overlap, while continuously noting the position of the
track guide roller (16).
• Avoid applying pressure to the
guide bar (22, 24)
during the welding process as doing so
could lead to welding faults.
• After finishing welding, pull the
hot-air blowers lock (15),
extend the
hot-air blowers (10)
up to the stop and
swivel them upwards until they engage.
• Afterwards, swivel the
track guide roller (16)
upwards.
• Use the
Direct heating button (35)
to switch off the heating so that the
welding nozzle (9)
cools down.
• Now switch off the device with the
main switch (19)
and disconnect the
power supply cord (1)
from the
electrical network.
• Wait until the device has cooled down!
• Check the
power supply cord (1)
and plug for electrical and/or mechanical damage.
• Use a wire brush to clean the
welding nozzle (9)
.
