§4.3.3 Wire Installation and Set-Up Guide
The importance of smooth consistent wire feeding during MIG welding cannot be
emphasized enough. The correct installation of the wire spool and the wire into the wire
feed unit is critical to achieving an even and consistent wire feed. A high percentage of
faults with MIG welders emanate from poor set up of the wire into the wire feeder. The
guide below will assist in the correct setup of your wire feeder.
(1) Remove the spool retaining nut. (2) Note the tension spring adjuster and
