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

8

to change the welding polarity of the machine

depending on whether you are MIG welding or flux-

9

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. 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.
