Note: 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 fac-
ing you. Use only the proper size drive roller
when using your welder.
Table 4 indicates which drive roller groove
should be used with each wire diameter size.

4. Find the side of the drive roller that is
stamped with the same wire diameter as
that of the wire being installed (see
Figure 6). Push the drive roller onto the
drive roller shaft, with the side stamped
with the desired wire diameter facing you.

5. Reinstall the Drive Roller Cap and lock in
place by turning it clockwise.
6. Close the door to the welder drive com-
partment.
SELECTING THE WELDING WIRE
This welder uses both four inch or eight inch
spools of 0.030 inch (0.8mm) or 0.035 inch
(0.9mm) self shielding flux-core wire. Steel
from 18 gauge up to 3/16 inch thick can be
welded with this wire.
NOTE:
•
Metal thinner than 18 gauge cannot be
welded with this machine. Attempting to do
12
Drive Roller Groove:
0.8
0.9
so will cause burn through (blowing holes)
in the metal you are intending to weld.
•
If a spool has developed heavy oxidation,
the only solution to the problem is to dis-
card the spool of wire.
If you have an oxidized spool of wire, do not
discard it until you have unspooled a few
turns of wire to see if the wire further down
on the spool is in usable condition, if not, –
discard the spool.
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.
Tech Tip: Before installing welding wire,
make sure that you have removed any old
wire from the Torch Assembly. This will help
to prevent the possibility of the wire jamming
inside the Torch Liner.
Be very careful when removing the welding
nozzle. The contact tip on this welder is elec-
trically hot whenever the torch trigger is
pulled. Make certain POWER is turned OFF.
1. Remove the nozzle and contact tip from
the end of the torch 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 and 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 7. The welding wire should always
come off the top of the spool into the
drive mechanism.
