Welding pressure:
The welding pressure is stepless adjustable and transmitted via a toggle lever to
the pressure rollers.
The equalisation of the pressure to both welded sections as well as on a welded
seam without test channel is guaranteed by the swivel head. This allows T-joints
to be welded without problems. During the welding process the pressure adjusts
itself linearly to the change in material thickness of the geomembrane liner.
Drive:
The double drive system is stepless adjustabke and electronically controlled.
Therefore, the speed always stays constant.
WELDING PARAMETERS
Attention
: Always do a test welding before real welding to find out the parame-
ters.
Welding temperature
Set the welding temperature with the up- and down buttons of the temperature
controller. The air flow is stepless adjustable with the potentiometer (depending
on material). Switch on the heat and let heat up for approx. 5 minutes.
