Check the parameters whilst welding is in progress
Welding speed, air temperature and air flow range are monitored continuously. If an actual value deviates from the
selected settings, this will be shown in the
Work display (44)
.
Actual value corresponds to the
setpoint.
The air temperature actual value
is lower than the setpoint. The
heat-up process is signaled by
flashing; the arrow is pointing
upwards.
The air temperature actual value
is higher than the setpoint. The
cool-down process is signaled
by flashing; the arrow is pointing
downwards.
Finishing welding
Once welding has been completed, remove the nozzle, using the
lever (10)
. This will retract the
hot-air blower
(9)
and stop the drive.
Then place the
overlap guide roller (18)
in the upwards position and use the
lifting device (5)
to remove the
hot-air welder from the ground.
Turning off the device
Use the
heating on/off key (40)
to turn off the heating. The device switches to cool
down mode and the blower switches off automatically after approx. five minutes.
Now turn off the device with the
main switch (11)
and disconnect the
power supply
cord (3)
from the electrical network.
• Wait until the device has cooled down.
• Check the
power cord (3)
and plug for electrical and/or mechanical damage. Damaged plugs
and the extension cables must not be used, due to risk of an electric shock.
• Use a brass wire brush to clean the
welding nozzle (8)
.
