HBS-SCD-3201
Stud Welding Unit (with wide range power supply) for CD stud welding and short cycle drawn arc stud welding according to current standards
Application
- Especially suitable for thin sheets (at least 0.5 mm), only CD
- Capacitor discharge and short-cycle drawn arc stud welding possible with one stud welding unit
Capacitor discharge – especially suitable for dia. 10 mm (collar stud) welding elements and problematic surfaces (e.g. galvanised sheets)
Short cycle drawn arc stud welding – requires only single-phase 85 to 265 V wide range power supply (no 460 V 3- phase current); for welding short cycle welding elements; best reproducibility of welds through storage of welding energy in capacitor battery prior to each weld;
Process variants
- Contact welding
- Gap welding
- Short cycle drawn arc welding
Equipment
- Welding with shielding gas (series)
- Automation (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
- Display of error codes – on LCD display
- Lift test – for gap welding guns and stud welding heads
- Library function – 8 programs (charging voltages) can be stored; library with stored welding parameters; additional customer-specific entries possible; user interface available in various languages; display of charging voltage in volts
- Process monitoring – recording and analysis of factors affecting the welding process by means of the process-
analysis factor (PAF); after each weld, the reference PAF value is compared with the actual value; display of the
actual and reference values; switchable automatic welding stop, if limits are exceeded; limits selectable in increments;
manual entry of PAF value possible (only CD) - RS232 interface – for data output; data and time of day are stored; welding parameters of each weld are logged (only CD)
Structure
- Extremely easy to operate
- Compact
- Robust – metal housing withstands rough treatment in shop and on site
- 115 V mains connection (instead of 460 V 3-phase current connection)
Safety
- With integrated mains filter (protection against voltage peaks)
- Use even with critical voltage supply
- 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 and internal temperature of stud welding unit- 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
