Welding Machines

Leister develops and manufactures automatic welders and welding machines that are used to weld thermoplastic membranes on roofs, landfills, tunnels, truck tarpaulins and shading systems.

Details

Welding With Data Recording

The GEOSTAR G5 LQS is an automatic welder used to weld geomembranes with the Leister Quality System (LQS). The LQS function allows data identification and monitoring of all welding parameters: i.e. speed, temperature and pressure. Thanks to built-in Wifi, wireless data transmission is easy and convenient. Via the LQS app, quality documentation, tables, and graphics are easy to create and, in addition, pdf and csv exports can be created

The maintenance-friendly automatic welder weighs less than 17 kg and is therefore lighter than the GEOSTAR G7. The sophisticated aluminum construction allows for optimal maintenance positions with easy access to the mechanical parts of the machine (both for cleaning components and converting). Furthermore, GEOSTAR G5 LQS is easy to use and the hot wedge can be replaced in less than one minute. The GEOSTAR G5 LQS easily and safely welds various geomembranes made of HD-PE, PP, LD-PE, TPO, FPO, PVC-P, CSPE and EIA with a material thickness ranging from 0.8 to 3 mm (30 to 120 mil).
