CDA 161

This is one of the new STUD Welding Machine products of CANAWELD which is a North American welding machine brands.

Stud Welding Unit For ARC stud welding and welding with Magnetic Rotating Arc according to current standards.

General Information

  • Especially suitable for thicker sheets of about 2 mm or higher
  • Welding of welding nuts type HexNut
  • For welding on perforated and non-perforated sheets

Process Variants

  • Short cycle drawn arc welding
  • Drawn arc welding
  • Welding with magnetic rotating arc


  • 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 exceed
  • 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 % weight savings vis-à-vis 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 % + 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 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-pre-flow 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
  • 2 in 1 – switchable from drawn-arc ignition to electrode welding
