AC Welding Control
KT-SST-AC0C4-230
Compact AC welding control unit with integrated transformer, designed for portable resistance welding applications powered from a standard 230 V single-phase outlet.

Description
The KT-SST-AC0C4-230 combines a 50 Hz AC welding control unit and welding transformer in a single compact, air-cooled housing. Operated through an integrated terminal with intuitive parameter control, it is the ideal entry-level solution for workshops, laboratories and field service applications where a full industrial inverter system would be oversized.
