Thyristor Contactors for Resistance Welding Machines
Thyristor contactors of models KТ-07, КТ-11-1, and КТ-12-1 are designed to equip resistance welding machines, including spot, seam, and projection welding. These devices ensure reliable commutation and control of single-phase industrial-frequency current, making them indispensable for automating welding processes.
Advantages of Thyristor Contactors
-
Wide Compatibility:
The contactors are compatible with welding cycle controllers such as RKSM, RKSM Mini, RKSM-K, RKSM-502, RKSM-801, and RKSM-801M. -
Synchronous Activation of Welding Current:
The contactors operate within systems equipped with control units that provide synchronous activation of welding current, enhancing the precision and stability of the welding process. -
High Performance:
Control is achieved via synchronous regulators that generate unipolar symmetric pulses at a frequency twice that of the mains supply.
Thyristor contactors of the KТ-07, КТ-11-1, and КТ-12-1 series guarantee efficient and stable welding operations, making them ideal for various industrial applications.
