Introduction

Wedge It Plus, manufactured by MUNSCH Kunststoff-Schweißtechnik GmbH, is a self­propelled, heat/pressure fusion machine, used for the seaming of thermoplastic geomembranes
and related materials.
Although this unit was designed for use in the field, it can be used in-house as well.

CAUTION

This machine is an electro-mechanical device with moving parts capable of exerting powerful force. Care

should be taken to prevent the accidental engagement of clothing, hair or personal extremities with any

moving parts.

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 machine

components may develop high surface temperatures.

Additional cooling of the heating wedge is not allowed

(water, chilling agents or similar)

Technical data:

Danger to life when opening the unit due to exposure to live components. Discon­nect 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 ca­bles 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!
