Plastic Welding - Unidrive 500 - LeisterYes! I am interested
The all new UNIDRIVE 500 combines manual and automatic welding in a 4.5 kg lightweight and easy-to-handle automatic welder. Thanks to its overlap technology, it is ideal for welding all thermoplastic single ply membranes such as PVC and TPO. Guided by two handles, the optimum pressure is generated for all basic welds. Its brushless motors are maintenance-free. What's more, welding with the UNIDRIVE 500 is three times faster than manual welding.

Reliable: Ergonomic handle for safe pressure during manual welding
Safe: Constant parameters and reliable quality – even with under voltage
Fast: Three times faster and more than manual welding using hot air gun
Customized: Reversible drive allows for welding in either direction
Practical: Compact and lightweight semi-automatic hot-air welder: 4.5 kg, 30 cm high
Flexible: Stainless steel nozzle for all welding application
Economical: Maintenance-free, brushless motors
Intuitive: Simple user guidance and operation via display

Whether on or at the roof parapet or welding domed skylights, connections, or small terraces – the dual drive of the UNIDRIVE 500 and the nozzle which can be rotated from left to right are impressive features which also show their worth when space is tight.

Thanks to intuitive user guidance, the UNIDRIVE 500 is easy to operate: Depending on requirements, the direction of the drive changes from left to right or vice versa based on the key combination entered. Undervoltage also poses no problem for the UNIDRIVE 500: A sensor ensures constant parameters and the quality of the weld is guaranteed. The display enables users to keep everything under control during welding.
