Features of the Round Base Welding Insulation Pin

  • Beveled Edge Cap: Prevents tearing of duct liner
  • Faster Welds: Forged diamond point design creates more electrical resistance for faster
  • Better Plating:Zinc and Chromate plating exceeds SMACNA standards and gives a more professional appearance.
  • Reduced Down Time:Consistent point quality reduces frequency of machine adjustments.
  • Stronger Welds: Hardened steel point assures positive electrical contact for complete sheet to pin fusion.
  • Applied with Standard Equipment: Easily applied with Automatic Pin Welder or most standard hand held or hopper fed resistance welders

Application equipments of Cup head pin

Cup head pin are welded by a stud welding machine, the application is very simple, when the insulation is ready on the sheet metal, put the cup head pin on the weld gun, weld them directly through the insulation to secure insulation. They now are widely accepted for in the thermal and acoustical insulation markets for use in industrial and commercial applications. Such as duct insulation, shipbuilding insulation etc.
