Details

Geomembrane Welding Machine With GPS

The GEOSTAR G7 LQS automatic welder can be used to weld geomembranes in underground engineering and in landfill construction. LQS allows data recording and monitoring of welding parameters. The pressure, welding speed and temperature are monitored and controlled via the digital display. Additionally, the digital display enables the user to monitor the mains voltage during the welding process.

The welding data can be transferred to the MyLeister app via WiFi. LQS enables quality documentation of the welding data quickly and easily, which can be transferred to the MyLeister app via WiFi. Thanks to its lightweight frame made of aluminum, the maintenance-friendly hot wedge weights roughly 18 kg (39.68 lbs.) and enables easy access to the mechanical parts of the machine (both for cleaning components and converting). The GEOSTAR G7 can easily weld various geomembranes made of HD-PE, PP, LD-PE, TPO, FPO, PVC, CSPE and EIA, with material thickness ranging from 1 to 3 mm (40 to 120 mil).
