Leister TRIAC DRIVE roof hot air welding 

This unique, semiautomatic welding tool is so lightweight and easy to handle it can be used anywhere. Its innovative hot-air unit, TRIAC AT/ST, sets real benchmarks. The flexible concept makes the TRIAC DRIVE an all-round tool that is universal in use. Depending on the weld overlap and application, an inside nozzle or outside nozzle are available.
This allows it to tackle all diverse applications on the roof. Especially on narrow circumstances along the parapet or round welding for patches.
Whether horizontal or vertical, if the hand tool is required for an application, the TRIAC AT can easily be removed from the holder, allowing for work without the drive unit. The TRIAC DRIVE is the ideal introduction to automatic welding.
