7. Work environment/Safety
The device should only be used in the open or in a well-ventilated area. Be careful not to burn the material during
welding.
Read and follow the safety precautions provided by the manufacturer for the material.
• The minimum cross-section must be observed when extension
cables are used.
• The extension cable must be authorized for the utilization site
(e.g. outdoors) and be marked accordingly.
• When a power plant is used as an energy supply, the following
applies for its nominal output: 2 × nominal output of the wedge
welder and fitted with FI switch.
• Power plant must be grounded.
• If you are using a mobile power generator, it should have a total distortion fraction of the sine waveform (THD=To-
tal Harmonic Distortion) of less than 6%. This information can be found in the technical data or can be obtained
from the supplier. When using mobile power generators with a THD value greater than 6%, damage to electronic
components may occur. Leister therefore recommends using portable power generators with inverter technology.
The hot wedge welding machine may only be switched on and off when the generator is running, otherwise the
electronic components may be damaged.
• Overlap width max. 150 mm
• Sealing sheets must be clean and dry between the overlaps and on the upper and lower side.
The wedge welder can be placed in three different positions during interruptions in work or for cooling down.
The clamping lever must be locked while doing so.
Prior to commissioning, check the power supply cord (1), the plug, and the extension
cable for electrical and mechanical damage. Use extension cables with protective con-
ductors only.
The wedge welder may not be used in areas with explosion and/or ignition hazards.
Ensure a stable position during work. The power supply cord (1) must be able to move
freely and must not hinder the user or third parties while working.
Place the wedge welder on a horizontal, fireproof support and ensure sufficient distance
from flammable materials and explosive gases!
