Cup Head Pins

Our CHP/CHP-ISOL weld fasteners allow the fixing of insulation material on sheet metal such as airducts in a single operation. Our welding machine ensures a high quality of weld on sheet metal up to a thickness of several centimetres. Due to long cables and to light weight, this machine is useful for jobsite. This machine uses the capacitors discharge technique and allows clips to be welded without overheating mark on the opposite side of the metal sheet.
The CHP pin consist of a steel pin firmly mounted on a galvanised steel washer. The CHP-ISOL are similar except that the shank is partially insulated. Thanks to this insulated shank and the use of the CHP gun, it is possible to fasten aluminium faced insulation.

Recommended assembly method


1.Fix ground clamp to the sheet metal. Lay insulation on sheet metal


2.Place the CHP pin on the magnetic chuck of the gun.
  
   

       3.Adjust the voltage according to the type and thickness of the sheet metal.
Press the pin through the insulation until the point meets the sheet metal and press the trigger.
