About Us

In 1942, as part of the emerging “Greatest Generation”, Carl Bertsche Sr. started Produciton Engineering. HE completed his engineering degree at the University of Cincinnati and was commissioned as 2nd Lt. in the U. S. Army. Carl faithfully served his country in Europe, and returned home after WW2. He began working for Precision Welder and Flexopress Company in Cincinnati, Ohio and soon became their chief engineer. 70 years later, we are still a family run company.  

Today we are the “One Stop Shop” for resistance welding equipment and supplies, including: controls, transformers, cables, holders, electrodes, weld caps, bar stock, chillers, weld checkers, nut feeders, electrode dressers, and much more. 

In addition, we represent several manufacturers that can provide design & build help for all types of production welding equipment, including: spot welding, projection welding, seam welding, GMAW work cells, laser welding, and electron beam welding. 

If you have reliable old equipment that needs a new control, or to be rebuilt, we can help to refurbish your old machinery.
