Inverter Arc Stud Welder - IT 2002

General Information

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

Application

Especially suitable for thicker sheets of about .093 inches (2 mm) or higher
Especially suitable for welding of concrete anchors/shear connectors for job site applications
Suitable for through deck welding

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

Advantages
Structure Extremely easy to operate Compact / Mobile – highly mobile thanks to compact dimensions and low weight (50% less weight compared 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% 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 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 possible for 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 for welding process
