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 inch diameter spool. Use the 2 inch spindle
adapter included with the machine to use 8 inch
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.
