My neighbor owns a Lincoln SA200 with a V4 Wisconsin, code 1667. One of
the brush holders broke and the parts lists on Lincoln Electric skips over
that code number. The part number for the brush holder is S6711A and it
takes a T7554 brush. Can this welder be updated with newer style brush
holders? Any help is appreciated.

There's a starter rebuilder - Schiroo Electric in Glencoe, MN. he can fix
anything with brushes 320-864-6200
