Risk of Burning
Then detach the
nut (12 A)
with an 11/16 inch
open-end wrench. The
welding nozzle (12)
can
now be removed. Handle the
welding nozzle (12)
carefully so as not to damage the air output
opening. Then mount the desired
welding
nozzle (12)
and securely tighten it.
Caution:
Completely cool the machine with the cool-down mode before changing the
welding nozzle (12)
.
The
welding nozzle (12)
may still be hot even following the cool-down mode.
A 25 mm
welding nozzle (12)
is mounted as standard. Nozzles are available in widths from 8 – 64 mm.
Before mounting a new
welding nozzle (12)
, use adjusting screw (Y) to turn the
welding nozzle (12)
as far as possible away
from the machine in direction (-Y). Before changing the
welding nozzle (12)
, allow the machine to completely cool down.
The Seamtek 900 AT is a hot-air welding
machine. Depending on the respective process,
some components can become incredibly hot.
Always operate the machine with due caution.
Danger:
The
welding nozzle (12),
heating
element pipe, and the
heating element protec-
tive pipe (24)
can be very hot during operation.
There is a risk of burning when touching these
elements. Never touch one of these components
while the machine is operating. These elements
may still be warm even following the cool-down
mode.
Hot air is discharged through a bypass when low-
flow nozzles are used.
Hot air may escape from the end of the bypass
in the process. Make sure that no one is in the
hazard zone.
