Battery MAXI - 90 minutes runtime
BAK continues to drive the development of professional plastic welding technology and set new standards in the market with innovative battery-powered solutions. With the new LiiOn battery MAXI, users can now benefit from even longer operating times for professional plastic welding applications.

With the LiiOn battery MAXI, BAK now offers even greater independence for professional plastic welding applications.
Depending on the nozzle and temperature settings, the new battery option provides up to 90 minutes of welding time. This means around 30% more runtime compared to the standard version.
The LiiOn was the first professional battery-powered hot-air welding tool and continues to offer by far the longest runtime on the market.
It is ideal for roofers, flooring professionals and tarpaulin fabricators who need powerful, cordless performance wherever they work. With an output of up to 1,200 watts, an adjustable temperature of up to 650°C, and an airflow of 150 l/min, the tool is designed for demanding professional applications.
The battery MAXI is available both as a LiiOn configuration and as a separate accessory. An alert provides timely notification when the battery is running low. Together with the high-quality backpack, the compact hot-air welding tool can be transported comfortably and used flexibly wherever it is needed.
