“FREAKING OUT IN RESISTANCE WELDING”

On February 11^th, Don DeCorte, Vice President of Resistance Welding Products at RoMan Mfg., gives a short 35-minute presentation on the effects of increasing primary frequencies in MFDC resistance welding controls and power supplies for use in automotive manufacturing. For many years, the “world standard” primary operating frequency for MFDC resistance welding controls and power supplies for use in automotive applications, has been 1,000 HZ. In recent years, a few Automotive OEM’s and Tier 1 suppliers have started to use MFDC resistance welding controls and power supplies operating at 1,200-2,000 HZ. Don explains the advantages, disadvantages, and practical limits, of increasing the operating frequency of the equipment.
