FAQs

The IT 1002 AT is designed for industrial arc stud welding on thicker sheets, including applications involving mild steel, stainless steel, and aluminum. It also supports specialized welding of HexNut and MARC sleeves.

The IT 1002 AT supports automated production through compatible automatic welding heads, programmable welding parameters, process monitoring, and automation configurations. It can be integrated into production systems requiring repeatable stud placement and controlled welding cycles.

The IT 1002 AT delivers up to 1,000 A of welding current and supports Drawn Arc and Short Cycle processes. This combination provides the controlled energy and penetration required for stud welding on thicker metal sections.

Yes. The IT 1002 AT supports conventional stud welding as well as specialized applications using HexNut welding nuts and MARC sleeves. This makes the system suitable for varied fastening requirements within industrial manufacturing and fabrication.

The IT 1002 AT includes microcontroller-based control, function monitoring, lift testing, error-code display, library functions, and process monitoring. Welding current can be adjusted from 100–1,000 A, with welding time adjustable from 5–1,000 ms.

Yes. The IT 1002 AT is designed for welding on both perforated and non-perforated sheets. The appropriate welding process, stud configuration, and parameters should be selected according to the workpiece material and application.

The IT 1002 AT is compatible with welding heads including the PAH-1, KAH 412, and KAH 412 LA. Selection depends on stud size, feeding method, automation requirements, and whether mechanical length compensation is required.
