WELDING OPERATIONS
SEQUENCE OF OPERATION
Wire Loading
Refer to Figure B.2 and B.3.
The machine power switch should be turned to the OFF (“O”) position before working inside the wire feed enclosure.
The machine is shipped from the factory ready to feed 8” (200 mm) diameter spools [2.2” (56 mm) max. width]. These spools fit on a 2” (50 mm) diameter spindle that has a
Note:When loading and removing the 8” Spools make sure that the wing nut (inside the wire spool spindle hub) is turned 90° from the wire spool spindle locking tab. If the wing nut is positioned in line with the locking tab, the tab cannot be depressed to load or unload the wire spool.

Be sure that this stud engages the hole in the wire spool.
To Wire Drive
Wire Spool must be pushed all the way on the spindle so that the spindle’s tab will hold it in place. The Wire Spool will rotate clock- wise when wire is dereeled.
Load an 8” (200 mm) diameter spool on the wire spool spindle shown in Figure B.2.
To use 4” (100 mm) diameter spools, the 2” (50 mm) diameter spindle must be removed (See Figure B.3). Remove the wing nut and spacer at the end of the shaft and remove the outside plastic wire spool spin- dle. The spindle can be stored in the wire feed com- partment. A 4” (100 mm) diameter spool is mounted directly on the 5/8” (16 mm) diameter shaft and held in place with the previously removed hardware. Also make certain the start end of the wire, which may pro- trude through the side of the spool does not contact any metallic case parts.

Note: The brake should be adjusted with a spool of wire installed. When properly adjusted it should move freely but not coast.
CAUTION
Some spools can have the start wire protruding from the side of the spool. This must be insulated from internal metal components otherwise electri- cal grounding faults will result and the machine will be seriously damaged.
Friction Brake Adjustments
1.With wire spool installed, check free movement and coast of the spool.
2.To tighten the brake turn the wing nut clockwise in 1/4 turn increments until coasting stops.
3.To loosen the brake turn the wing nut counter- clockwise in 1/4 turn increments until the wire spool moves freely without coasting.
