Welding Wire Installation
The MigWeld140 welding machine can use wire spools up to 8" diameter (200mm) and a
maximum width under 2" (50mm). If you use the smaller 4" diameter (100mm) wire spools
the 2" (50mm) spindle adapter must removed.
For installation of a 8" (200mm) welding wire spool (See Figure D-1).
Install the 8" (200mm) welding wire spool on the wire spindle ○
spool spindle tab engages the hole in the wire spool. (Note: The wire spool will rotate
clockwise when wire is dereeled).
For installation of a 4"diameter (100mm) welding wire spool (See Figure D-2).
The 2" (50mm) diameter spindle must be removed ○
remove the outside plastic wire spool spindle ○
directly on a 5/8" (16mm) diameter shaft and held in place with the previously removed
