If there is wire already installed in
the welder, roll it back onto the wire
spool by hand-turning the spool
counter-clockwise. Be careful not
to allow the wire to come out of the
rear end of the gun without holding
onto it or it will unspool itself. Put
the end of the wire into the hole on
the outside edge of the wire spool
and bend it over to hold the wire in
place. Remove the spool of wire
from the welder.
Loosen the drive roller setscrew
and pull the drive roller off the drive

The drive roller has two wire
size grooves built into it.. When
installing the drive roller the
number stamped on the drive
roller for the wire size you are
using should be facing away
from you. If you can read the
wire size you are using on the
drive roller, it is installed
backwards. Use only the
proper size drive roller when
using your welder_
Find the side of the drive roller that
is stamped with the same wire
diameter as that of the wire being
installed (see Figure 4, and if in
metric, see DESCRIPTtON)_ Make
certain the spacing wast_er is still on
the motor shaft and push the drive
roller onto the motor shaft, aligning
the setscrew with the flat side of the
drive shaft. Make sure the side
stamped with the desired wire
diameter is away from you
