THREADING WELDING WIRE THROUGH THE DRIVE MOTOR TO THE WELDING GUN
This welder uses only self shielding flux-core wire in either 0.030" or 0.035" size (0.8 or 0.9mm). To
install the welding wire follow the procedure outlined below:
1.
Turn the power switch to the off position and unplug the welder from the power supply.
2.
Remove the contact tip and nozzle from the end of the torch.
3.
Ensure that the drive roller is installed in the proper position for the wire size being used.
4.
Unlock the Pressure Adjuster
(FIG. C-C2)
and lift up on the Rocker Arm
(FIG. C-C3)
. Ensure that
the wire drive roller is appropriate to the welding wire size see the previous section describing the
installation of the drive roller. The drive roller comes installed for 0.030" (0.8mm) wire.
5.
Pull out the welding wire from the wire spool carefully.
NOTE:
Do not let go of the wire or the
entire spool could unravel.
6.
Cut off the small piece of the curved segment at the front of welding wire and straighten the
welding wire approximately 3.0" long.
7.
Thread the welding wire through the Guide Pipe
(FIG. C-C4)
and over the wire Drive Roller and
into the torch hole.
8.
Reattach the Rocker arm and reset the Pressure Adjuster.
9.
Turn on the machine and set the wire speed to about ‘5’.
10.
With the gun pointed away from you and others, depress the trigger to begin feeding wire.
NOTE:
Watch the drive roller to see if any slipping is occurring between the roller and wire, if so,
turn the machine off and tighten the Pressure Adjuster ¼ turn and test again.
11.
Once the wire exits the end of the torch, install the contact tip and nozzle. Cut the wire about
1/4" from the end of the contact tip.
OPERATION
Your Eastwood Flux Core 90 can be used to perform a large number of different types of welds, all of
which will require practice and testing before using on an actual project piece. This following welding
process is just a baseline to get you started.
1.
Connect your ground clamp to the work pieces that are to be welded. Make sure the ground
clamp contacts are placed on a clean piece of metal free of paint, grease, rust, oils, etc. It is
recommended to place your ground clamp as close to the weld area as possible.
2.
Assess your weld area and make sure the welding area is also cleaned of any paint, grease, rust,
oils, etc.
3.
Plug in the welder and switch to the ON position.
4.
Depress the Welding Gun trigger pointing the welding gun away from your body and then let go
of the trigger and cut the wire back to ~1/4" stick out length.
5.
Wearing your welding helmet, gloves, and long sleeve shirt and pants, put the end of the wire
sticking out of the gun into the joint to be welded.
6.
Position the Welding Gun so that it is perpendicular to the base metal with ~20° tilt back.
