Transformers of inverter resistance welders

摘要

The present invention relates to a transformer of an inverter resistance welder. The transformer of an inverter resistance welder according to an embodiment of the present invention can comprise: a first cooling block (310) disposed between a first coil unit (102) and a second coil unit (104); and a second cooling block (320) disposed between the second coil unit (104) and a third coil unit (106). In the first and second cooling blocks (310, 320) of the transformer of the inverter resistance welder, a cooling medium is circulated to cool heat generated from the first, second, and third coil units (102, 104, 106).
