WELDING PARAMETERS
Welding temperature
Set the welding temperature with the UP – DOWN keys of the temperature controller positioned
on the left of the front panel. The switch ON - OFF of the heating is positioned under the temper-
ature controller. Do not start to weld before the actual
temperature corresponds to the set value.
An alarm signal (AL) will be shown in the lower right corner of the display if the actual tempera-
ture is lower as the set value; in this case the motor cannot be started or, if in function, will stop
automatically.
Welding speed
Set the welding speed by the potentiometer on the front panel, the motor can be switched on and
off by the switch near the potentiometer. The speed shown on the display corresponds to the ac-
tual welding speed.
Welding pressure
Engage and position the welding tool onto the material to be welded.
Pull the toggle lever without engaging the hot wedge. By rotating the adjustment screw the
drive/pressure rollers will lightly touch the material to be welded, in this way you will define the
point zero (0) N of pressure. Unhook the toggle lever for the locking mechanism and open the
toggle lever. Set the desired pressure by rotating the adjustment screw, to every single step of
rotation you will set 90N of pressure on seam. Then lock the desired pressure with the locking
screw.
If the maximum welding pressure (1400 N) is exceeded, mechanical damages
may occur.
