. Consult your
local electricity board if necessary.
Check adjustment of the nozzle.
The mains supply must conform to ICE 60364 standard as well as to the national
standards.
Connect the machine to the mains. The voltage rating stated on the tool should
correspond to the mains voltage.
When using extension cords the minimum diameter of the cable must be observed.
Cord length up to 25 m, cord diameter 2.5 mm². (On 120V we recommend cord
diameter 4.0mm²).
Welding procedure:
Adjust the welding parameters.
The welding temperature must be reached.
Overlap seam:
Position the welding machine on the overlapped geomembrane liner or film.
Align the guide roller to the overlap.
Lower the hot air tool and slide the nozzle between the overlapped geomembrane liner
or film. The machine starts automatically.
Guide the welding machine along the overlapping. Always watch the position of the
guide roller.
Tape/Vandalism/Custom tape seam:
Position the welding machine on the geomembrane liner or film.
Position the guide roller on the cant or mark.
Lower the hot air tool and slide the nozzle between the geomembrane liner and the
band. The machine starts automatically.
Guide the welding machine along the cant or mark. Always watch the position of the
guide roller.
After welding lower and raise the hot air tool.
Turn off the heating with the switch on the hot air tool and allow the welding nozzle to
cool down.
Switch off the tool with the main switch.
MOUNTING
!!!ATTENTION!!!
ALWAYS unplug the tool before mounting on the tool!!!
1.0. Changing the heating element (only when the device has cooled down)
1.1. Swivel out and lock the hot air system
1.2. Loosen four screws at the flange of the nozzle
1.3. Pull off the nozzle
1.4. Pull off the mica tube (careful, fragile)
1.5. Remove the gasket
1.6. Pull off the defective heating element
