Introduction
Wedge It ECO, developed and manufactured by MUNSCH Kunststoff-Schweißtechnik GmbH, is
a machine with an own actuator, joining thermoplastic foils and similar materials by heat and
pressure. The Wedge It ECO is developed for outdoor use, but may also be used indoor.
Attention
This machine is an electromechanical unit with moveable parts, operated by high pressure. Take
care in using the Wedge It Multi, especially the moveable parts (no contact with clothes, hair,
bodily parts).
Crushing hazard!!!

Note: These operating instructions must always be available to the machine operators.
Make sure to read them carefully before placing the unit in service.
Very important!
Switch off the heating wedge whenever the unit is out of service for prolonged periods.
This will prevent heating up of the machine due to radiating heat. Otherwise some ma-
chine components may develop high surface temperatures.
Additional cooling of the heating wedge is not allowed
(water, chilling agents or similar).

Safety
Danger to life when opening the unit due to exposure to live components. Discon-
nect the power supply (all poles) before opening the unit. A damaged connecting
cable may cause fatal electrical shock. The rated voltage indicated on the unit type
tag must match the mains voltage. If required, check with your electric utility.
Improper use of the welding unit poses a fire and explosion hazard, especially when
working in the vicinity of flammable materials and explosive gases.
Not suitable for use in explosion hazard areas!!!
Risk of burns!!!
Do not touch the heating wedge when hot. Always allow unit to cool down.
Protection Class I equipment
Connect the unit only to power outlets equipped with a protective conductor. Each
interruption of the protective conductor presents a hazard. Only use extension ca-
bles with the correct conductor cross-section and a protective conductor.
FI
FI switch required for personal protection.
Unit may only be operated under observation. Heat may propagate to flammable
materials outside the range of vision.
Protect the unit from moisture and direct rainfall!

Overlap weld with air channel
The Wedge It Multi produces an overlap seam with a
width of 45 mm (including air channel) at an overlap
of approx. 130 mm.

(Other weld widths and welding seams

different hot wedges and pressure rolls.)

Preparation of the Unit
A special preparation or configuration of the working unit is not absolutely necessary. Only the
working temperature and the welding speed have to be adjusted and you have to do a test weld-
ing.
The joining pressure is created automatically with a spring packet by the machine.
Take a slat out of the test welding and check it (deep injection, continuity of the welding joint,
fracture behaviour). After this test, please adjust temperature and welding speed.
fig. 5 fig. 5a
After changing the material thickness, the distance of the wedge to the actuator rolls has to be
checked and adjusted.
Proceed as follows:
Please cut off two stripes of 50mm width and two stripes of 20mm width from the welding mate-
rial.
Put the 50mm stripes between the rolls (distance 1).
Please make sure, that the material does not project too much into the machine. Otherwise it
would get in contact with the wedge. Now close the machine by pushing the actuating lever (pos.
1, fig. 1), until it snaps into the locking bolt. Loosen the screw on the hot wedge positioning (pos.
7). Set the desired thickness of the geomembrane according to the marks on the metal (fig. 5a).
Please check, whether the 20mm stripes now can easily get inserted above and below the hot
wedge (distance 2 and 3) and make sure that the wedge does not get into contact with the actu-
ator rolls.

ATTENTION!!!
If the distance between hot wedge and actuator rolls is too high, your
welding will be of low quality.
If it is too low, the machine gets too high impact.
NOTE:
Before every welding procedure, check the machine for damages.
Check the actuator rolls and the hot wedge for pollution and remainders.
The welding joint must be clean in the area of the overlapping between
the foils as well as above and below the foils.
When operating the unit with power supply from a generator
set, make sure that the generating capacity is sufficient.
Attention!!
Never leave the unit unattended and never lay it down
for prolonged periods with the heating current activated.
This will cause unnecessary heat development and
ultimately damage to the machine components.
Attention!!
Never allow the machine to run with the nip rollers
locked in place and no material in the machine. This
will destroy the nip rollers and the wedge assembly.

Temperature setting
Abb. 6
Please set the desired welding temperature on the temperature controller, using the up and
down arrows.
Speed setting
Abb. 7
Please set the desired welding speed (USA: feet/min; Rest meter/min) spinning the adjustment
wheel of the speed. Confirm the setting by pushing the wheel shortly.
After reaching the set welding temperature, you can start welding.
Welding
Please put the machine into the geomembranes, start the motor and close the actuating lever.
Reopen the actuating lever when reaching the end of the line.
Please put the welding automate on the face looking into the travelling direction, if you stop
welding or if you have reached the end of the line, to have a well heat dissipation.
