HBS-CI-03 Stud Welding Gun (for insulation)

CD stud welding according to current standards.


  • Especially suitable for thin sheets (at least 0.5 mm)
  • ISO – especially suitable for welding on cupped head pins (for fixing heating, ventilation and air-conditioning mats – HVAC)
  • Especially suitable for insulation mats with and without an aluminum cover. The cupped head pin has a special tip that
    permits particularly easy penetration of the insulation materials. Variably adjustable spring pressure allows the stud
    welding gun to be optimally adjusted to a wide range of material densities
  • The fixing method with cupped head pins replaces the complex procedure: weld on pin – press mat over pin – affix clip – pinch off or bend over projecting tip

Process variants

  • Contact welding

  • Rigid casing made of impact-resistant plastic
  • Torsion-resistant basic shell (casing) to accommodate all function elements (e.g. ball bearing guide) and accessories (e.g. foot ring)
  • Zero-play ball linear bearing for guiding the welding piston
  • Sealed welding piston guidance
  • Ergonomic design
  • Compact dimensions
  • Mechanical structure tested in production


  • Lock-in spring adjustment
  • High level of security to prevent the selected settings from being changed inadvertently
  • Guidance system protected against spatters


  • Individual adjustment options for optimum welding results
  • Optimum handling and fatigue-free operation
  • Optimum operation also at places that are difficult to access
  • Welding on painted sheets is possible (clean, smooth, and flat surfaces and grounding required)
  • No damage to the reverse of thin zinc-plated sheets when complying with specified welding parameters, particularly in
    the case of cupped head pins with 2 mm diameter (zinc and corrosion protection on the reverse is retained)
  • Low energy expenditure
  • Very fast fixing: Press the cupped head pin through the mat, welding in 3 milliseconds
  • Low power input for pins with dia. 2 mm diameter
