Size 6 MFDC Fast Rise Time (FRT) TDC-7537

Ideal for heavy gauge aluminum, steel, spot and projection welding applications, RoMan’s Fast Rise Time MFDC power supply provides an alternative to traditional capacitive discharge welding (CDW), and it has proven to be less expensive in many applications when compared to the CDW process. While it can be used for all types of resistance welding applications, it is ideal for mass-produced projection/stud welded parts in the aerospace, appliance, automotive, medical, industrial, and many other markets.
