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
for changing 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 I.D. spindle
adapter included with the machine to use 8 inch
diameter spools. The Wing Nut 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. Top and Bottom Drive Roll – Drives the wire
through the drive system. The drive roll has a
groove to match the specific wire type and diam-
eter. Refer to Table B.1 for available drive rolls.
b. Inner & Outer Wire Guide – Guides the wire
between the Top and Bottom Drive Roll and
through the wire drive. The inner guide has a
groove to match a particular wire diameter.
Refer to Table B.1 for available wire guides.
c. Drive Roll Tension Thumbscrew – Turning
clockwise increases the force on the drive rolls
and turning counterclockwise decreases the
force.
12. SPOOL GUN SWITCH - Pre-Installed switch per-
mits either spool gun welding with the Magnum
100SG or standard welding with the Magnum
PRO 100L.
