About Powertran Transformers
Powertran’s story begins in 1956, long before the era of global supply chains and automated design software—back when craftsmanship, engineering intuition, and hands-on problem-solving defined the manufacturing landscape. Born as an internal division of Weltronics, Powertran’s initial responsibility was to design and manufacture transformers needed for their automotive welding systems and controllers.
That mandate—build components that perform flawlessly—became a culture. A deep understanding of electrical behavior. A commitment to precision. And a belief that the best products come from designers and builders working side by side.
Through the 50s, 60s, and 70s, Powertran became one of Weltronics’ most trusted internal strengths, known for transformers that formed the backbone of demanding welding systems. These were years of iteration, craftsmanship, and industrial consistency—defining the reputation Powertran still carries today.
