RoMan designs and manufactures three types of water-cooled transformers in a wide variety of models for the Automotive and Industrial Resistance Welding markets, they include MFDC, AC and DC/Low Frequency transformers. They are designed to meet any resistance welding application requirements—from small spot welds to large projection welds, and can be integrated with any brand of controls, weld-guns or robotic systems.
- MFDC Lightweight
- AC Transgun Type
- AC Fixture Type
- AC Machine Type
- Heavy Duty MFDC and Low Frequency DC Power Supply/Rectifiers
The products shown below feature our standard models. However, both the size and capabilities of our transformers and power supplies can be designed to meet specific applications. They are available in various primary voltages, various frequencies, and secondary voltages.
Size 6 MFDC Fast Rise Time (FRT) TDC-7537
Ideal for heavy gauge aluminum, steel, spot and projection welding. Alternative to capacitor discharge (CDW).
Reversing DC RDC-8030
Ideal for welding aluminum and special steel applications where polarity considerations are necessary.
AC Fixture Type Transformers
Ideal for multi-spot-welding fixtures. Available in multiple frame sizes.
AC Machine Type
Ideal for press, seam, rocker arm, cross wire and other welding applications. Available in multiple frame sizes.
Low Frequency DC Power Supply/Rectifiers
DC Power Supply/Rectifiers Ideal for ring projection, flash-butt and rim welding as well as corrosive plating environments.
Safety Ground Reactors
An important part of AC Resistance Welding, ensures safety during the welding process.
