Inverter Arc Stud Welder - IT 90

Application

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

Process Variants

Drawn arc with ceramic ferrule (ARC)
Drawn arc with shielding gas (ARC)
Short-cycle (SC)

Equipment

Inverter (2,000 A) with options for 4 outputs, process monitoring and shielding gas

Mild steel

Stainless steel

Aluminium

M3 to M24 - #4 to 1"

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 (optional)

Advantages
Structure Extremely easy to operate Compact / Mobile – highly mobile thanks to compact dimensions and low weight (50% weight savings in relation to 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 IP Code: IP 21
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
