Inverter Arc Stud Welder - IT 90

Inverter Arc Stud Welder - IT 90

Application

  • Especially suitable for thicker sheets of about (2 mm) or higher

Process Variants

  • Drawn arc with ceramic ferrule (ARC)
  • Drawn arc with shielding gas (ARC)
  • Short-cycle (SC)

Equipment

  • Inverter (2,000 A) with options for 4 outputs, process monitoring and shielding gas
Mild steel
Stainless steel
Aluminium
M3 to M24 - #4 to 1"
Features
  • 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
  • Lift test – for gap welding guns and stud welding heads
  • Library function – automatic specification of welding current and welding time through selection of stud diameter according to welding range (with and without shielded gas); fine adjustment via arrow keys
  • Process monitoring – recording and analysis of factors affecting the welding process; after each weld, the reference and actual values are compared; display of the welding energy input; switchable automatic welding stop if limits are exceeded
  • RS232 interface – for data output; data and time of day are stored; welding parameters of each weld are logged
  • 4 gun connections (optional)
Advantages
Structure
  • Extremely easy to operate
  • Compact / Mobile – highly mobile thanks to compact dimensions and low weight (50% weight savings in relation to conventional stud welding units
  • Robust – metal housing withstands rough treatment in shop and on site
Safety
  • 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)
  • Control unit galvanically separated from welding lines – high degree of functional safety
  • Optimal protection against external interferences
  • IP Code: IP 21
Welding
  • Display – infinitely adjustable power setting; easy monitoring of all functions via LED displays; easy operation via membrane keyboard and digital display; setting of welding parameters, programs, shielding gas, automation and process monitoring possible; digital display of current, welding and gas-preflow time (optional; pneumatic feed time for automation); separate settings for welding current and welding time
  • Powerful – built-in power reserves
  • Trouble-free changing of welding voltage polarity possible by reconnecting welding current and ground cables
  • Outstanding welding quality – very high arc stability even at weak welding currents
  • High process flexibility – high clock frequency (30 kHz) of stud welding unit allows highly dynamic regulation of welding process
