6. Tighten the setscrew, while holding the drive roller in place.
7. Remove the screws that retain the inlet guide tube.
Replace the plastic inlet guide tube with the supplied brass
inlet guide tube. Secure screws.
Note: The tapered side of the brass inlet guide tube
should be as close to the rollers as possible without
touching.
• It is not necessary to reinstall the plastic inlet guide
tube when switching back to the standard drive
roller. However, if you experience some binding,
readjust the brass inlet guide tube slightly away
from the drive roller.

INSTALL THE WELDING WIRE

WARNING
Electric shock can kill! Always turn the POWER switch
OFF and unplug the power cord from the ac power source
before installing wire.
Be very careful when removing the welding nozzle. The contact
tip on this welder is electrically hot as long as POWER is turned
ON. Make certain POWER is turned OFF.
1. Remove the nozzle and contact tip from the end of the gun
assembly.
2. Make sure the proper groove on the drive roller is in place
for the wire being installed. If the proper groove is not in
place, change the drive roller as described above.
3. Unwrap the spool of wire then find the leading end of the
wire (it goes through a hole in the outer edge of the spool
and is bent over the spool edge to prevent the wire from
unspooling) BUT DO NOT UNHOOK IT YET.
4. Place the spool on the spindle in such a manner that when
the wire comes off the spool, it will look like the top
illustration in Figure 6. The welding wire should always
come off the top of the spool into the drive mechanism.

5. If you are installing a four-inch spool of wire, install the
drive brake hardware on the top of the spool of wire
according to Figure 7A. If you are installing an eight-inch
spool, install the spindle adapter and drive brake hardware
as shown in Figure 7B. The purpose of the drive brake is
to cause the spool of wire to stop turning at nearly the
same moment that wire feeding stops.

6. Once the drive brake hardware is installed, set the spool
tension. With one hand, turn the wire spool and continue
turning it while adjusting the tension on the spool. With
your free hand, tighten (turn clockwise) the wing nut that
holds the spool in place. Stop tightening when drag is felt
on the wire spool that you are turning, then stop hand
turning the wire spool.
