5. Wire Drive Polarity. MIG welding requires Positive
(+) polarity. Connect the short power cable from
the wire drive to the positive (+) output terminal and
tighten wingnut.
6. Work Lead Connection. Slide the lugged end of the
work cable through the hole in the machine front
and route cable through the strain relief as shown in
figure B.14. Place lug on the negative (-) output ter-
minal and tighten wing nut.
D. LOAD WIRE SPOOL
(See Figure B.15)
1. Locate the sample spool of .025"(0.6mm) L-56 solid
MIG wire and place onto wire spool spindle. Orient
the spool so that the wire feeds off the top of the
