HFR generators for hardening

High-frequency and medium-frequency generators for induction hardening are based on the same design as high-power welding generators. The key technological requirement is parameter stability, above all of the output power and frequency during the induction heating process. For automated hardening processes in series production using hardening machines, another important criterion is the ramp-up time to the required power. HFR generators reach the required power within 100 milliseconds as standard, with any output inductor.
