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
Process monitoring - recording and analysis of factors affecting the welding process; after each weld, the reference and actual values are compared; display of the welding energy input; switchable automatic welding stop if limits are exceeded
RS232 interface - for data output; data and time of day are stored; welding parameters of each weld are logged)
4 gun connections (optional)

Extremely easy to operate
Compact
Mobile - highly mobile thanks to compact dimensions and low weight (50% weight savings vis-à-vis conventional stud welding units)
Robust - metal housing withstands rough treatment in shop and on site

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

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, automation and process monitoring possible; digital display of current, welding and gas-preflow time (optional: pneumatic feed time for automation); 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
