3.04 Installation Of Welding Wire Spool
Refer to Figure 3-1.
NOTE
The wire spool hub supplied with the unit is
provided for mounting a 12" diameter spool
of wire. Optional adapters are available
allowing an 8" diameter spool of wire or a 14
pound coil of wire to be used.
1. Remove the wire spool hub nut by turning
counterclockwise.
2. Orient and slide the spool of wire over the wire
spool hub so that the wire will feed off the bottom
of the spool as the spool rotates counter
clockwise. Make sure that the alignment pin on
the hub enters the hole in the backside of the wire
spool.
3. Replace the wire spool hub nut and turn clockwise
to a snug position.
NOTE
The wire must feed from the bottom of the
spool. If it comes off the top the spool will
have to be removed and turned around.
3.05 Adjustment Of Spool Tension
Adjust the wire spool tension so that the wire will feed
freely into the input wire guide. However, the spool of
welding wire must not “coast” when wire feeding stops.
To adjust the wire spool tension, tighten or loosen the
hub tension bolt accordingly (Refer to Figure 3-1).
NOTE
Excessive tightening of the hub tension bolt
will result in a shorter motor life
