• mains under-voltage
• overlap of the geomembrane liner too wide
• dirt on the drive rollers (20/21)
• max. welding pressure (1000 N) has been exceeded
• high welding speed with large sudden overload
(ie anchoring trench, T-joints....)
Perform a test welding according to the welding instructions of the material manufacturer
and the national standards or guidelines. Check the test welding.
• Drive/pressure rollers (20/21), idler wheel (28), lower guide plate (30) and upper guide plate (29) as well
as the hot wedge (7) must be clean.
• Film and sealing membranes must be clean between the overlap and on the upper and lower surfaces.
