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

Fast Welding Machine

The GEOSTAR G7 is a maintenance-friendly, easy-to-use hot-wedge welding machine. It is optimized for underground engineering, landfills and mines. The sophisticated frame made of solid cast aluminum is advantageous. Furthermore, the integrated clamping and handle locking mechanism guarantees simple, single-hand operation. At welding speeds up to 12 m/min (39ft/min), the GEOSTAR G7 welds geomembranes that cover large areas.

An additional advantage is that the hot wedge can be replaced in less than one minute, thanks to the new wedge connection. Geomembranes made of HD-PE, PP LD-PE, TPO and FPO with a material thickness between 1 mm and 3 mm (40 and 120 mil) are easily welded with the GEOSTAR G7. Leister will check additional materials for their weldability on request. The key difference between the GEOSTAR G5 and the GEOSTAR G7 is the wedge length. Thanks to the 130 mm long wedge, noticeably higher performance is possible with the GEOSTAR G7.
