Utilisation:
he Laron is an automatic welding machine for overlap welding to weld
geomembranes (geomembranes width 20mm or 40mm). he machine must only be
used to weld geomembranes (PE, PVC, PO, ECB, EPDM, CSPE and bitumen) at
the edge and uneven surfaces.
Automatic welding machines are manufactured according to the latest technology
and in compliance with safety requirements.
Any improper use may result in dangers for the operator or third parties or may
adversely affect machines and assets.
Only use the automatic welding machine if in technically perfect condition and for the
purposes for which they are intended while observing the operating instructions.
For the neglect or for damages resulting from it the manufacturer / supplier will not
accept any liability .
Any utilisation of the automatic welding machine, for other purposes than those for
which it is intended, is subject to the consent of the manufacturer / supplier.
Work on electrical parts of welding machine may only be performed by an electrical
engineer in compliance with electro-technical rules.
Indication of special risks:
All automatic welding machines may only be held and operated using the handles
provided for this purpose.
A risk of burning exists on all uncovered metal parts. Avoid contact with these parts
as they may achieve temperatures of up to 650°C.
Attention: Heat can reach combustible materials which are hidden.

Safety area:
he hot air stream of the automatic welding machine may not be directed to
temperature-sensitive objects or living things. Ensure that a safety distance of 2 m is
observed in all directions
.
Do not point the hot air stream onto the same position for
a long time.
Security:
Before connecting the tool to the mains, check the rated voltage.
he mains voltage must correspond to the rated voltage shown on the tool plate.
Pursuant to sec. 55 of VDE 0 100 the automatic welding machine must be operated
using a protective switch or an isolation transformer.
Do not use the automatic welding machine if the connecting line or the plug is
damaged, repairs have to be done by the manufacturer or authorised service
personnel.
Extension cords:
When using extension cords the minimum diameter of cables must be observed.
Extension cords must be approved and marked for their place of utilisation.

Guide roller adjustment:
- Bring the automatic welding machine into the welding position.
- Push the transport roller to the right in welding position
take care that the spring sheet engages.
- push the guide roller downward and fix it with the hexagon nut on the
threaded bar.
Outside edge of the overlap, outside edge of pressure roll and
outside edge of guide roller must form a line.
(see following sketch).
