Advantages of the Rechargeable, Battery Operated, TruTool F 301 Seam Locker

The Trumpf TruTool Battery Operated F301 provides cordless locking of thin sheet metal and easily closes seams on curved or straight duct. The adjustment to the sheet thickness is automatic and the forward feed guarantees a consistent and tight seam. The head is suitable for flange heights of 9 mm – 13 mm and for sheet thicknesses of 0.75 – 1.25 mm. The automatic adjustment of the head adapts to the sheet thickness and gives a consistent result on each cut.

Individual electronic cell monitoring in the machine and in the charger protects the battery against overload, overheating, and deep discharge. The robust battery cells have a low energy drop and always remain cool. A microprocessor analyzes the battery data and controls an optimal charge and discharge process. The result is high power combined with a long service life for the battery. You can therefore work almost non-stop. The 2 Ah and 4 Ah rechargeable batteries only require 10 – 30 minutes to be charged to 80%.
