Inverter Arc Stud Welder - IT 1002

Inverter Arc Stud Welder - IT 1002


  • Especially suitable for thicker sheets of about .093 inches (2 mm) or higher
  • For welding on perforated and non-perforated sheets
Process Variants
  • Short cycle drawn arc welding
  • Drawn arc welding
  • Welding with ceramic ferrule (series)
  • Welding with shielding gas (series)
  • Automation (optional)
  • Process sequence control (optional)
  • 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
  • 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 (only for version gas/automation/process control)
  • Extremely easy to operate
  • Compact / Mobile – highly mobile thanks to compact dimensions and low weight (50% less weight compared to conventional stud welding units)
  • 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%
  • 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 reliability)
  • Control unit galvanically separated from welding lines – high degree of functional safety
  • 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; 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 by reconnecting welding current & ground cables
  • Outstanding welding quality – very high arc stability even at weak welding currents
  • High process flexibility – high clock frequency (30kHz) of unit allows highly dynamic regulation of welding process
  • 2 in 1 – switchable from drawn-arc ignition to electrode welding
