Disconnect the machine from the mains
supply before undertaking any maintenance
work.

8.1 ADJUST WELDING TEMPERATURE

The welding temperature can be adjusted to
suit the strap thickness and strap quality:
– For narrow, thin straps = low temperature.
– For wide, thick straps = high temperature.
– Open table top.
– Loosen two hexagonal head parker screws (12/1)
and remove cover (12/3).
– Set potentiometer (12/2) to desired temperature.
– ST = Default (factory setting)
– Pos. 0 = lowest temperature, approx. 220°C
– Pos. 7 = highest temperature, approx. 325°C
The warming-up time for the heating element
is about 45 seconds.
– Mount the cover (12/3) and fi x it with the hexagonal
head parker screws (12/1), close table top.

8.2 ADJUST HEIGHT OF HEATING ELEMENT

First of all let the heating element cool down.
– Open table top
– With a long hexagon-socket screw wrench (placed
through hole in side wall) turn coupling in direction
of arrow, until the heating element has reached the
position shown in Fig. 13.
– With the nuts (13/3) set the heating element (13/2)
in such a way that the upper side of the heating
element is a little (approx. 0.2 mm) over the top of
the strap separator (13/1).
