A success story

Thanks to our creativity, we are regularly at the forefront when innovations are presented. One of our most popular innovations includes the LiiOn, which was the first professional battery welding tool in the industry. You’re able to weld for 45 minutes. Similar products that have emerged in recent years range from about 15 to 20 minutes, so they are still not comparable with ours.

The LiiOn is our answer to the demand for a cordless hot air tool and the first professional solution, a backpack with a rechargeable battery and a hand-held heating device including a charger. A package for working independently, far away from any socket.

The LiiOn is an ideal tool for service and repair work. It'll quickly improve your operation, carry out the assigned work and then you are already on to the next project. This is how the small jobs are carried out today thanks to our LiiOn.
