Especially suitable for welding of concrete anchors/shear connectors for job site applications
Suitable for through deck welding

Process Variants

Equipment

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; fine adjustment via arrow keys
Extremely easy to operate
Mobile – highly mobile thanks to compact dimensions and low weight (50 % weight savings vis-à-vis conventional stud welding units)
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 – use even with critical voltage supply (- 10 % + 10 %)
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
EMC test
High-voltage test with log
IP-Code: IP 23
Also permits operation outdoors

Welding

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
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

Suitable Stud Welding Guns

Optional Accessories

A 22
Stud Welding Gun (damped) for ARC stud welding according to current standards

General Information
