Printable Specsheet



  • Microcontroller – for precise process times, optimal functional reliability and maximum operating convenience
  • Function monitoring – automatic function test following power-up; monitoring of all internal system functions
  • Display of error codes – on digital display
  • Lift test – for gap welding guns and welding heads


  • Extremely easy to operate
  • Compact
  • Robust – metal housing withstands rough treatment in shop and on site


  • With integrated mains filter (protection against voltage peaks)
  • Optimal for construction sites with large mains voltage fluctuations – use even with critical voltage supply (- 10% + 10%)
  • EMC test
  • High-voltage test with log
  • Retriggering lock-out – prevents welding on a welding element that has already been set
  • Thermal monitoring of transformer – automatic shutdown in case of overheating
  • Temperature-regulated ventilator – reduces noise and dust in the stud welding unit (greater system reliability)
  • Consistent separation of transformer and control unit – protects electronic components against dust and thermal loading
  • Control unit galvanically separated from welding lines – high degree of functional safety
  • Cooling-air tunnel – channeling of cooling air to the transformer protects electronic components against dirt and dust
  • Optimal protection against external interferences
  • Protection class IP 23
  • Also permits operation outdoors


  • Display – infinitely adjustable power setting; easy monitoring of all functions via LED displays; display of welding and gas-preflow time (optional: pneumatic feed time for automation); control and monitoring of all system functions
  • Powerful – built-in power reserves
  • Trouble-free changing of welding voltage polarity is possible by reconnecting the welding current and ground cables

Suitable stud welding guns

  • A 12, A 16, AI 06
  • CA 08
  • PAH-1 (only suitable for automatic version)
  • KAH 412, KAH 412 LA (only suitable for automatic version)
