Laying of material:
o
Width of overlap from 80 to 140 mm
o
Make sure that the surfaces of geomembrane liners, above and below, are cleaned,
as well as between the overlap.
Mains supply at least 3kW (generator) supplied with an RCCB.

Operating conditions
Connect the tool to the mains
Start the tool with the main switch/level
Welding procedure
Adjust the welding parameters (see page no. 4)
Wait until the wedge has reached the adjusted temperature.
Guide and position the welding machine onto the overlapped geomembrane liner or film.
Switch on the drive motor with the foreseen switch.
Engage the hot wedge onto the overlapped geomembrane liner or film.
Push down the toggle lever to obtain the blockade.
Check the welded seam (wash/seam thickness reduction). Eventually adjust the welding
speed with the potentiometer.
Drive / adjust the direction of the welding machine with the guide handle so that the mini-
mum overlap is guaranteed
1cm before the end of the welded seam release the pressure lever, pull back the hot wedge
and switch off the motor with the switch.
