What to do if Miller Welding System brushes are damaged?
If the brushes of your Miller Welding System are damaged, replace them if they are chipped, broken, or have less than 1/4 in. (6.4 mm) of brush material remaining. Also, make sure to install the brush so that the curved surface on the end of the brush matches the curve of the motor, and secure it with a cap.
