worldTRANSFORMER

For decades, NIMAK has been developing and building welding transformers ranging from individual customised solutions to standardised medium-frequency welding transformers in accordance with the relevant automotive standards. 

Regardless of whether you are looking for AC transformers, medium-frequency transformers, short-pulse transformers, DC transformers or transformers for KE applications, NIMAK has the right solution for every application. 

Before delivery, each transformer undergoes a 100 per cent quality check and is also available with UL certification on request. 

NIMAK transformers are characterised by a particularly high degree of efficiency and therefore contribute to energy efficiency in production. 

Thanks to optimised cooling water flow, the thermal load is reduced and the service life of the transformers is increased.
