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 (with and without shielded gas); fine adjustment via arrow keys
Structure
- Extremely easy to operate
- Compact
- Mobile - highly mobile thanks to compact dimensions and low weight (50% weight savings vis-a-vis conventional stud welding units)
- 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%)
- 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
- Protection class IP 23
- Also permits operation outdoors
Welding
- 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
- 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
