KAH 412 - Automatic Stud Welding Head

Automatic Stud Welding Head - KAH 412

Description / Features


  • Especially suitable for thin metal sheets from 0.5 mm.


  • Zero-play ball linear bearing for guiding the welding piston, to ensure maximum precision and reproducibility for welds
  • Sealed welding piston guidance
  • Integrated lift and spring-loaded adjustment
  • Digital display (1/100 mm) for the position of the welding piston using integrated measuring system
  • Direct reading for the adjusted plunge and lift dimension
  • Pushbutton detent system to facilitate changing the feeding tube
  • Electronically controlled


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


  • Individual adjustment options for optimum welding results
  • Welding on painted sheets possible (clean, smooth and flat surfaces and grounding required)
  • Manual or fully automatic stud feed possible (welding element is automatically pushed through the feed tube in the chuck)
