For Toroidal Cores TCW Series will operate with a wide range of steel qualities, producing outside transformer core diameters ranging from 8 mm to 250 mm with a range of strip width from 3 to 100 mm. The machine will strictly adhere to the core winding specifications as it is manufactured to highest engineering parameters activating advanced electronics in logic control sequences. The integral welder is also under fully automatic control of the HMI and PLC that brought into operation at the beginning and end of the transformer core winding cycle. The welding system has been selected to complement the associated engineering standards of the TCW Series to give the highest degree of reliability.
