Equipment: Inverter Stud Welders: Inverter IT 3002

General Information

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

Process Variants

• Short cycle drawn arc welding
• Drawn arc welding

Equipment

• Welding with ceramic ferrule (series)

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 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
