WELDING OPERATIONS
SEQUENCE OF OPERATION
Wire loading
Changed figures:
Changed text in right column:The welder is shipped from the factory ready to feed 12"
(305mm.) diameter spools with 4" (102 mm.) maximum width. These spools fit on a 2"
(51 mm.) diameter spindle that has a built in friction brake to prevent overrun of the
spool and excess slack in the wire. Adjust the brake tension with the thumbscrew on the
spindle hub, until the reel turns freely but with little or no overrun when wire feeding is
stopped. Do not overtighten.
To use 8" (200 mm.) diameter spools the S18221 Spindle Adapter must be mounted on the
spindle in between the 8" spool and the retaining collar. See Figure B.3a.
Refers to Figure B.2a and B.3a
Be sure that this stud engages
the hole in the wire spool.
