Keep your classic Lincoln SA-250 welder/generator running strong! This is a genuine Lincoln Electric replacement part: a set of two exciter brushes, part number T14875. These carbon brushes are critical for the electrical system, specifically for the exciter on machines powered by the Perkins 3.152 diesel engine. Over time, brushes wear down and need replacing to maintain proper electrical contact and welding output. This set is brand new, unused, and comes in its original Lincoln packaging. It's a straightforward maintenance item for anyone who owns or services these industrial welders. If your machine is having arc stability issues or not generating power correctly, worn brushes are a common culprit. A simple and affordable fix to restore your reliable SA-250 to full working order.
