If the device was allowed to cool down beforehand, this will be followed by a static
display of the setpoints for the most recently set welding parameters.
At this stage, the heating, blower and drive are switched off.
Now switch the heating on with the Heating On/Off button.
After connection, the start screen appears briefly on the display of the operating
unit (2) with the version number of the current software release and the device
designation.
As soon as you have switched on the heating, you will see a dynamic display of the
current air temperature (setpoint and actual value). All welding parameters (welding
speed, temperature and air volume) can be set.
• Make sure that the welding temperature has been reached before
commencing work (LED stops flashing). 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 required.
Preparing for welding
• Once you have prepared the working area and the hot air welder in accordance with the description, connect
the hot air welder to the supply voltage.
• Use the main switch (19) to switch the hot-air welder on.
