NOTE: The following procedure describes a

complete replacement of all primary and sec-

ondary transformer coils. Adapt the procedure

for the specific coils you may be replacing.

1. Apply a coating of Lincoln Electric E2547

Epoxy Mix along both sides of the bottom

iron (lamination) assembly in the areas where

the coil sides will be mounted. Coat the

areas no closer than .38 inches from the top

edge of the iron. See Figure F.27, arrows. Be

sure that none of the epoxy drips onto the

top of the iron assembly where it will meet the

top assembly.
