UNIDRIVE 500 

Leister Technologies

The Leister Technologies UNIDRIVE 500 compact semiautomatic welding machine combines manual and automatic welding in a 9.9-pound (4.5-kg) handy plastic welding device with a service-friendly brushless motor. The reversible UNIDRIVE 500 can be used for geomembrane installation, tunneling, and patches and repairs. Thanks to its overlap technology, it’s ideal for welding various thermoplastic membranes, such as polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). With an ergonomic handle for consistent pressure, the UNIDRIVE 500 is up to three times faster than manual welders.
