CDA 221
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
Application
- Especially suitable for thicker sheets of about 2 mm or higher
- Especially suitable for welding of concrete anchors/shear connectors for job site applications
- Suitable for through deck welding
Process Variants
- Short cycle drawn arc welding
- Drawn arc welding
Equipment
- Welding with ceramic ferrule (series)
- Welding with shielding gas (series)
Advantages
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; fine adjustment via arrow keys
- Extremely easy to operate
- Mobile – highly mobile thanks to compact dimensions and low weight (50 % weight savings vis-à-vis conventional stud welding units)
- Compact
- 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 %)
- 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
- EMC test
- High-voltage test with log
- IP-Code: IP 23
- Also permits operation outdoors
Welding
- 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
- 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 (optional); digital display of current, welding and gas-preflow time; separate settings for welding current and welding time
