Continuously Line 5-Foot Wide Ductwork


The new PowerPinner 7105HS boasts the quickest cycle time and most reliable welds available. Thanks to a technological breakthrough, the 7105HS high speed welder is built with the same high quality materials you have come to expect form Gripnail. Functioning without any mechanical reeds switches, the 7105HS on-board computer has been turbo-charged for peak performance. The new Programmable Logic Controller produces welding speeds never before seen without sacrificing welding quality.


Contractors who regularly line large fittings and straight duct will find the convenience of the 7105HS speeds their assembly and reduces fabrication costs. The weld head ravels a full 60 inches for lining 5-foot wide duct. The head is moved with a multi-position extension arm and glides on specially designed bearings, while all wires are reinforced in a wire sleeve and securely housed in an energy chain.
