3-phase direct current
The 3-phase DC technology is hardly used in new systems. In retrofit projects of existing systems, it can make sense and be economical to maintain the existing 3-phase transformer with rectifier unit and to replace only the welding control including the thyristor power section. HIE offers the right controls, power units and the necessary know-how for such projects across manufacturers. Talk to us if you are planning to retrofit your 3-Phase DC resistance welding machine. We are happy to help.
