• 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 (10)
.
• Define the
welding parameters for drive (19),
air temperature (22)
and
air volume (25)
on the respective
potentiometer.
• Now switch on the heating [
Direct heating button (24)
].
• 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.
After the welding, actuate the foot pedal or the
pressure switch (21)
, the
motor for generating preheated air
(1)
extends and the drive stops automatically.
• Use the
Direct heating button (24)
to switch off the heating so that the
welding nozzle (18)
cools down.
• The
LED (23)
begins flashing at the heating button.
If the device is switched off without the cooling process being adhered to, the device may become severely damaged.
No warranty or guarantee claims can be made for damage or malfunctions resulting from this.
Commencing welding
• Actuate the
pressure button (21)
or the foot pedal to start the welding automatically.
• The drive motor starts automatically as soon as the
hot-air blowers (1)
are swiveled in.
Guiding the material during the welding process
• Guide the material with a good tension during the welding process
Risk of clamping injuries!
A danger of clamping injuries exists with the tilting mechanism when the hot-air blowers swivel in
and out.
Only switch off the device with the
main switch (10)
when
LED (23)
stops flashing and disconnect
the power supply cord from the electrical network.
Wait until the device has cooled down / LED has stopped flashing. If the cooling is not adhered to, the
device may become damaged.
Check the power supply cord and plug for electrical and/or mechanical damage.
Clean the two filters of the
hot-air blowers (1)
and the
welding nozzle (18)
with a wire brush.
Risk of burning!
Do not touch heating element, nozzle and components in the immediate vicinity
of the nozzle when hot. The device should always first be allowed to cool down.
Do not point the hot air flow at people or animals!
Risk of entanglement!
During operation there is a risk of entanglement on the drive roller.
