B. CONNECT LEADS AND CABLES ON
THE MACHINE
(See Figure B.7)
1. Open the case side door
2. Slide the connector end of the gun and cable
through the hole in the machine front and into the
gun connector bushing on the wire drive.

into the wire drive and tighten the molded hand
screw to secure the gun connector.
4. Plug the gun trigger lead connector into the 4 pin
gun trigger receptacle on the machine front.
5. Wire Drive Polarity. Flux cored welding requires
negative (-) polarity. Connect the short power
cable from the wire drive to the negative (-) output
terminal and tighten threaded knob.
6. Work Lead Connection. Slide the lugged end of
the work cable through the hole in the machine
front and place on the positive (+) output terminal
and tighten threaded knob.
C. LOAD WIRE SPOOL
(See Figure B.8)
1. Locate the blue labeled 4"(102mm) diameter
spool of .035”(0.9mm)NR-211MP flux-cored wire
and place onto wire spool spindle. Orient the
spool so that the wire feeds off the top of the
spool.
2. Secure spool in place by tightening the wing nut
against the against the spacer that holds the wire
spool on the spindle.
3. Open the pivot arm assembly by rotating the ten-
sion arm assembly down and lift pivot arm assem-
bly up.
4. Remove drive roll by turning the twist lock that holds
the drive roll on. Install the .030”/.045”(0.8mm/1.1mm)
