WIRE FEEDER WELDERS (140, 180 MODELS)

(See Figure B.3)

8. WELDING GUN CONNECTOR BUSHING &

THUMBSCREW – Provides electrical power to the
welding gun. The thumbscrew holds the welding
gun into the connector block. (Front of Machine,
Side Door and Wire Drive Cover have been
removed for clarity of Items 8 and 9).

9. OUTPUT TERMINALS –These connections allow

to change the welding polarity of the machine
depending on whether you are MIG welding or flux-
cored welding.

(See Figure B.4)

10. WIRE SPOOL SPINDLE AND BRAKE – Holds a

4”(102mm) diameter spool. Use the 2”(51mm)
spindle adapter included with the machine to use
8”(203mm) diameter spools. The thumbscrew
sets the brake friction to prevent the spool from
over rotating when the trigger is released.

(See Figure B.5)

11. WIRE DRIVE & COMPONENTS – Feeds wire

from the wire spool through the drive and through
the welding gun to the weld.

a. Drive Roll – Drives the wire through the drive

system. The drive roll has a groove to match
the specific wire type and diameter. Refer to
Table B.1 for available drive rolls.

b. Liner & Outgoing Guide – The liner guides the

wire between the bearing on the Pivot Arm
Assembly and Drive Roll and through the outgo-
ing guide.

c. Drive Roll Tension Thumbscrew – Turning

clockwise increases the force on the drive roll
and turning counterclockwise decreases the
force.
