Most coil lines are capable of running at 50 feet per minute, but had to slow down to 25 ft/min. when applying welded duct liner fasteners. Gripnail introduced the industry's first 50 ft/min. two decades ago. Ever since we have been centered on continuously making industry leading improvements to the design. The PowerPinner 50 is capable of welding a full range of weld pins from 1/2" - 2" as close as 6" centers on sheet metal from 16 - 26 gauge. The PP50 comes standard with a multitude of quality ensuring features that lead to unprecedented reliability. 

The Power Pinner 50 and the coil line's insulator are connected with a simple chain drive. This drive powers the heads forward at the same speed as the sheet metal, whenever the machine is pinning. As soon as the machine stops pinning, air cylinders move the drive heads back towards the insulator. The programmable logic control unit (PLC) optimizes the head travel so that full ten-foot sheets may be insulated with pins on six-inch centers. The split pin track keeps a reserve of pins ready to load in the lower track every time the heads return to the starting position. A single weld-setting switch controls the weld time for all heads while the PLC optimizes the dwell time. Operators only need to increase the weld setting for longer pins or thicker sheet metal. Each head has an on/off switch so that the machine can accommodate narrower coils of sheet metal.
