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 diame-
ter 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 diameter. 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 diame-
ter. 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 counter-
clockwise decreases the force.
12. SPOOL GUN SWITCH - Pre-Installed switch permits either
spool gun welding with the Magnum 100SG or standard
welding with the Magnum PRO 100L.
