Magnetic Specialties Inc. shipped and commissioned two power supplies used in a continuous brazing furnace by a tool manufacturing company. The new power supplies, rated 125 kW and 100 kW, were designed as direct replacements for a pair of existing, obsolete power supplies that continuously failed. The brazing furnace has silicon-carbide heating elements, which increase in resistance as they age. To compensate for this, the output transformers feature a tapped secondary winding. These taps are connected to a rotary tap switch for easy tap changing. As the elements age, the tool manufacturer can select a higher output voltage range via the tap switch. They will use the metering feedback to know when the tap needs to be changed.

The utilization of electromagnetic induction for heat-treatment purposes is no longer a novelty. However, the current excitement associated with induction heat treatment may suggest otherwise.
