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 (joining pressure, welding speed, welding temperature). It also has an voltage display to continuously 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).

- Complete Training of Leister Tools by Leister Trained Engineers Included in Every Order
- 45% higher performance than GEOSTAR G5
- Drive motor has 100% more power than GEOSTAR G5
- Robust cast aluminum frame
- Wireless data transmission via Wifi
- Welding parameter reports via the myLeister app
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).
