Inverter Arc Stud Welder - IT 50

GENERAL INFORMATION

Application

Especially suitable for thicker sheets of about (2 mm) or higher

Process variants

Short cycle drawn arc welding
Drawn arc welding

Equipment

Welding with ceramic ferrule (series)
Welding with shielding gas (series)
Automation (series)
Process sequence control (series)

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
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 (series)

Advantages
Structure Extremely easy to operate Compact / Mobile – highly mobile thanks to compact dimensions and low weight (50% weight savings compared to conventional (like) 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, 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
