6.4 Starting the device

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!
• 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)].

6.5 Welding Sequence

• 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.
Risk of clamping injuries!
A danger of clamping injuries exists with the tilting mechanism when the hot-air blowers swivel in
and out.
Risk of entanglement!
During operation there is a risk of entanglement on the drive roller.
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

6.6 Finishing welding

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.

6.7 Switching off the device / Maintenance

• 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.
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.
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.
