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 is possible by reconnecting the 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
