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 - RS232 interface – for data output; data and time of day are stored; welding parameters of each weld are logged
Structure
- Extremely easy to operate
- 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 – safe to operate with mains voltages ranging between 85 to 265 V (wide range power supply); 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
- Optimal protection against external interferences
Welding
- Display – infinitely adjustable power setting (charge reversal via set-point switch); easy monitoring of all functions via LCD display; user-friendly operation via large LCD display
- Powerful – built-in power reserves
- Electronic regulation of charging – allows high clock rates
- Trouble-free changing of welding voltage polarity possible by reconnecting welding current and ground cables
- Use of special capacitors (developed for stud welding)
- Capacitance switching – 66,000 F or 132,000 F
