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.
After the welding data has been recorded, it can be transferred to the MyLeister app via WiFi. LQS enables fast and easy creation of quality reports are available in pdf and csv format. Thanks to its lightweight frame made of aluminum, the maintenance-friendly hot-wedge welder weighs just 39.68 lbs and offers easy access to the mechanical parts.
