IKING Cup head insulation pins for glass wool and rock wool board install
IKING's cup-head pin weld fasteners allow the fixing of insulation material on sheet metal such as HVAC system (airducts/air ducts) 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 on construction site.
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 IKING Rock Wool Aluminum Insulation Pin for Air Duckconsist of a steel pin firmly mounted on a galvanised steel washer. And cup-head-pin with plastic sleeve 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.

1.The capacitor battery will be charged according to chosen charging voltage.
The stud (with ignition tip) is placed onto the work piece and pressed by a spring in the welding gun onto the work piece (contact). The current circuit is closed.
2After triggering the welding process, the rapidly increasing current evaporates the ignition tip and ignites the arc.
Stud and work piece are melted.
3The stud is moved forward to the plate.
4The arc is cut as soon as the stud touches the work piece
5The molten zones are joining and solidifying.
6Welding time is ≤ 3 msec.
7Recommended plate thickness should be 1/10 d, but not less than 0.5 mm.
